NGX Configuration Sheet- POWERCELL Outputs

December 2, 2024/0 Comments/in Wiring /by admin

We have completely re-engineered our Infinitybox system to bring the latest in wiring and body control technology to anyone wiring a hot rod, street rod, resto-mod, kit car, race car or Pro-Touring build. We have also re-engineered the NGX configuration sheet for this system. This new configuration sheet format makes it easier to read, gives more detail and gives all of the wire colors needed to connect to your switches and your accessories in your car or truck. This is the standard configuration that comes loaded on all new IPM1 kits. With our inCODE NGX programming tool, you can modify this configuration to meet the needs of your unique project.

This link will take you to the Front Engine configuration for our IPM1 kit. Watch the resources section of our website for other setups including the Rear Engine configuration. This blog post will walk through the details for the POWERCELL output assignments and the outputs on the MASTERCELL NGX. Watch out blog for details on the inMOTION NGX inputs and outputs.

To start, the configuration sheet is broken down into the different cells in the Infinitybox NGX system. This includes the front & rear POWERCELLs and the different inMOTION NGX cells for the doors (driver, passenger, driver rear & passenger rear). Our IPM1 kit comes standard with one MASTERCELL NGX and two of our POWERCELL NGXs. You can add as many inMOTION NGX door modules as you need for your car or truck. Most customers will add 2 or 4 inMOTION MGX modules to their system as accessories depending on if they are working on a 2 or 4 door car. Since the MASTERCELL NGX has low-current outputs to drive indicators on the dash, we added a page that details the wiring for these. Lastly, we added pages that detail all the wires in the MASTERCELL A & B connector harnesses.

For the front & rear POWERCELL pages, we’ve reorganized the columns to make this easier to read. The first column lists the function assigned to each POWERCELL output. This includes things like turn signals, ignition, starter solenoid, lights, cooling fans and fuel pumps. Any output that is labeled as OPEN is an auxiliary. There is no set function assigned to the output. Its corresponding input will turn it on and off.

The next column gives the address of the POWERCELL. By default, the front POWERCELL is addressed as 1 and the rear POWERCELL is addressed as 2.

The next column lists the POWERCELL output by number for the function. There are 10 outputs on a POWERCELL and they are listed in numerical order. Some functions list multiple outputs. Examples include the 4-ways and the One-Button Start. In these cases, the function uses two different outputs. The 4-ways use the left and right turn signal outputs. The One-Button Start function uses the outputs for both the ignition and starter.

The next column gives you the POWERCELL output connector that the output is connected to. The manual for your IPM1 kit has a diagram that identifies the A & B output connectors on the POWERCELL. Please pay attention to this diagram carefully. The A & B connectors are interchangeable on the POWERCELL.

The next column defines the “personality” assigned to the POWERCELL output and its corresponding input. The personality is how the output behaves when it is turned on. The most basic and common personality is “track”. Outputs assigned the track personality turn on when the input is turned on and turn off when the input is turned off. The input tracks the state of its input. You can learn more about the other available personalities by clicking this link.

The next column lists the wire color for each output on the POWERCELL output harness. Please note that the output harness colors for the outputs are the same for the front and rear POWERCELLs. Pay attention to the POWERCELL address to make sure you are connecting to the right output.

The last three columns tell you the details for the MASTERCELL inputs that are controlling each POWERCELL output. The input number, the MASTERCELL connector (A or B) and the wire color are listed.

After the POWERCELL details, the next page details the low-current outputs on the MASTERCELL NGX. These outputs give you easy access to low-current outputs to drive indicators on your dash. There are 8 of these outputs. The first 4 are assigned to the left-turn signal indicator, the right-turn signal indicator, the high-beam indicator and the illumination for your gauges. The next 4 are auxiliary outputs and can be set up as an advanced feature of the MASTERCELL NGX. Contact our tech support team for details.

Dakota Digital GSS-3000

May 31, 2022/0 Comments/in Wiring /by admin

This blog post will show you the connections that you need to make between your Infinitybox 20-Circuit Kit and the Dakota Digital GSS-3000 Universal Gear Shift Sender. The GSS-3000 is designed to drive the gear selector indicators on your dash from any automatic transmission. Their kit has a rotary potentiometer that connects to the shift linkage on the transmission. It learns the position of the different gears and sends signals to indicators on your dash to show you what gear you are in. It is a simple and clever product. The Dakota Digital GSS-3000 has contacts that are designed to drive your back up lights when you have the transmission in reverse. It also has a set of contacts for a Neutral Safety Switch. This sends out a signal when the transmission is in park or neutral and it is safe to start the engine. Your Infinitybox system can take in these two signals to easily drive your back up lights and manage your Neutral Safety Switch. Keep reading to learn more.

Before you go any further, it is important that you read and carefully understand the instructions for your Dakota Digital GSS-3000 Universal Gear Shift Sender. You can download these instructions from their website by clicking here. This blog post is only going to cover the ignition power to the GSS-3000, the neutral safety signal and the connection to the back up lights. Please follow their instructions for the rest of the wiring to the module. This picture will show the wiring diagram for the connections to the GSS-3000.

Picture of Infinitybox Wiring Diagram for the Dakota Digital GSS-3000

First, you need to provide key-on ignition power to the module. When the key is in the run position, the module will get its power. You’re going to tap into the ignition output on your front POWERCELL. Check your configuration sheet for the wire color for your ignition output. You can splice into this wire directly or you can use one of our Splice Saver Kits to make a simple and clean connection for ignition power.

Next, you can take their Back Up signal and use it to control the back up lights in the back of you car. The advantage of doing it this way is that you’re running less wire. The signal will come from the GSS-3000 in the front of the car and connect to the MASTERCELL, also in the front of the car. The back up lights will get their power from the rear POWERCELL. You are not running a wire all the way from the GSS-3000 in the front of the car to the back up lights in the rear of the car. The GSS-3000 puts out a positive signal for the back up lights. You need to use one of our inVERT Minis to flip this to a ground signal. See the details in the wiring diagram for how to make these connections.

Lastly, you can use the Dakota Digital GSS-3000 to send the MASTERCELL the signal for the Neutral Safety Switch. The MASTERCELL needs to see a ground signal through the input for the Neutral Safety Switch. Check your configuration sheet for specifics on the wire color for your system. This blog post will get you more details on the Neutral Safety Switch input. In a lot of transmissions, there is a switch built into them that will give you this signal for when it is safe to start the engine. If your transmission does not have a built-in safety switch, you can use the signal from the GSS-3000. This is a ground signal from their SAFETY terminal. We recommend wiring a 1N4001 diode in series with the MASTERCELL input to isolate the MASTERCELL from the GSS-3000. This blog post will get you more details about wiring this diode in line. When you have the transmission in the park or neutral position, the MATERCELL will get the signal that it safe to start the engine.

The is an important consideration here regarding using the GSS-3000 neutral safety signal and the Infinitybox built-in One-Button Start feature. This feature will not work if you are taking the neutral safety signal from the GSS-3000. Since the GSS-3000 is getting its power from the ignition output from your POWERCELL, the module will not trigger the neutral safety signal in time for the MASTERCELL to process this. You will need to use an external neutral safety switch if you want to use our One-Button Start feature and the GSS-3000.

Soldering Components In-Line

May 27, 2022/1 Comment/in Wiring /by admin

Okay… we do our best to not take things for granted. In all of our blog posts, we always try to give you as much fundamental information on the material that we are presenting. Every once in a while, we get called out by our customers for not explaining something thoroughly. This post is intended to fix this. In a lot of our blog posts and wiring diagrams, we show components installed in-line with a MASTERCELL input or a connection to ground.

In our last blog post, we showed wiring a 10K pull up resistor on a brake-pedal switch. You can see that blog post here. In other blog posts, we’ve shown wiring diodes in-line between a trigger on an ECU and a MASTERCELL input. You can click here to see a recent example blog post. Someone just asked us an obvious question on our last blog post. “How do I install the diode or the resistor in the wire”. We’ll show you how. This isn’t the only way to do this but it is our recommended way to do this.

There are three important factors to consider when installing an in-line component in a wire. First, you need to have good electrical connection. Second, you need to protect it mechanically. Lastly, you need to protect the joint from the environment.

These steps will show you how to solder an axial, leaded component in-line with a wire. A leaded part has metal terminals coming off its ends. An axial part has the leads running along the axis of the component. This picture shows you a good example of an axial, leaded diode.

Example of a simple diode

Speaking of diodes, remember that they have a direction to them. Check our wiring diagram for proper orientation of the diodes. Resistors do not have a direction so you can install them either way in your wiring harness.

The first step is to strip back the insulation on the wire you’re connecting to your component.

Next, you want to twist the strands of the copper wire together. This will make the next steps easier by keeping the strands together.

Next, twist the strands of the wire with the lead coming from your component. We recommend leaving some length of the lead at the end as shown in this picture.

The next step is to make a good electrical connection between your wire and the lead on your component. This needs to be soldered. A good soldering iron and electrical solder will make this job easy. You want to make sure that you are heating the joint thoroughly and that the solder is flowing between the copper wire and the lead on your component. When you’re finished, the joint should be shiny. If your joint looks grey or dull, you need to apply more heat and solder. We also recommend keeping the solder on the joint between the copper wire and the lead on the component. You do not want the solder to wick up the copper wire under the insulation. This will make the joint inflexible and it could fail over time.

Once you have the joint soldered, clip off the extra length of lead on the component.

Repeat this process for the other side of your component.

Now you have a good electrical connection between your wires and your component. The next step is to protect the component mechanically and from the environment. To do this, we recommend a good quality heat shrink tubing. Heat shrink tubing does what its name suggests. It shrinks around a joint when you heat it. Cut a length of heat shrink tubing that is slightly larger in diameter than the component that you soldered in line. You want the length of this tubing to extend past the exposed area of your joint by about 1/2″ on both sides.

Use a hot air gun to heat the tubing and shrink it over the component and the joints. We know that a lot of guys like to use lighters or torches to do this but we really recommend a hot air gun for better control and safety.

The heat shrink tubing is going to do two important things. First, it is going to mechanically strain relieve your joints. This will keep the joints from failing due to vibration of mechanical stress. We recommend that you zip tie these components in the harness to minimize any bending or movement as an added precaution. Secondly, the heat shrink tubing is going to protect the joints from exposure to moisture, dirt and other chemicals in your car.

Soldering in-line components in your harness is a simple thing to do. If you have any additional questions about this, please click on this link to contact our technical support team.

+12 Volt Brake Light Signals

May 24, 2022/1 Comment/in Wiring /by admin

Our MASTERCELL uses ground switching to control all of the electrical functions in your car. There are many advantages to ground switching. You need less wire, you are only triggering a signal so the there is less current flowing through the switch and you can get the ability for combinational logic easily. This link will take you to a good description of how the MASTERCELL inputs work and how you should wire the switches connected to your Infinitybox system. Your brake pedal switch is no different. You run your MASTERCELL input for your brake lights to the switch on the pedal. You connect your brake lights to the outputs on your rear POWERCELL. When you step on the pedal, the MASTERCELL tells the rear POWERCELL to turn on the brake lights. It’s pretty simple. This blog post will get you more details on wiring your brake lights. Normally, you’re going to use ground switching between your brake pedal switch and your MASTERCELL. There are some times when you need a positive 12-volt signal from your brake pedal to interface with other electrical systems. This blog post is going to show you a few easy options to get this +12 volt brake light signal.

There are several external electrical systems that need a positive signal from the brake pedal. Examples of these systems include transmission controllers to manage the torque converter lock up. Other examples include cruise control systems to disengage the system when you step on the brakes. Another example is an external PKE system with one button start. You must step on the brake pedal to safely start the car. In a typical Infinitybox wiring set up, there is no battery voltage at the brake pedal switch. An option to get this +12-volt signal would be to tap off the brake light on the rear POWERCELL. This requires that you run a wire from the back of the car up to the front. This may also be an issue if you’re using out 1-filament brake light set up. We’re going to give you a few simple options to get this +12 volt brake light signal from the pedal to keep the wiring in your car short.

Before we get too far, you need to carefully read and understand the instructions for the electrical system that you’re interfacing with your Infinitybox system. Make sure you know exactly what signal you need from your brake pedal switch. Some systems need a +12-volt signal when you step on the brakes and a ground signal when your foot is off the pedal. Other systems need a 12-volt signal when you’re foot is off the pedal and ground when you step on the pedal. Make sure you understand what you need. The following examples will show you how to accommodate any of these options.

The next thing that we need to review is the difference between Normally Open and Normally Closed switches. These designations describe what the contacts in the switches are doing when the switch is in its normal state. A Normally Open (NO) switch is off when you are not pushing it. You have to push the switch to turn the switch on. A Normally Closed (NC) switch is on when you are not pushing it and off when you push it. The majority of the switches in your car are Normally Open (NO) but there are a few exceptions.

There are a few different types of brake pedal switches. Two terminal switches are the most common. There are also 4-terminal switches. Within the 4-terminal switches, most of these have a set of Normally Open (NO) contacts and a set of Normally Closed (NC) contacts.

Let’s start with the 2-terminal switches. These have a set of Normally Open contacts. The switch is off when you are not pressing the brake pedal. When you step on the pedal, you close the contacts. This makes an electrical connection between the two terminals on the switch. In a normal Infinitybox set up, you ground one of the terminals on the switch and connect the second terminal to the MASTERCELL input for your brake lights. When you step on the brake pedal, you make an electrical connection between the MASTERCELL input and ground. This is a very simple set up, however you don’t have +12 volts at the switch.

This diagram shows you how to wire your 2-terminal brake pedal switch to get a +12 volt signal and a ground signal for the MASTERCELL. It uses an Infinitybox inVERT Mini to flip the 12-volt signal from the switch to ground the MASTERCELL input.

Instead of grounding one terminal on the brake pedal switch, connect it to the ignition output on your front POWERCELL. When the ignition is on in the car, you will have voltage on this terminal on the switch. You can splice into the ignition output wire on the POWERCELL or you can use one of our Infinitybox Splice Saver kits to make this connection. You will then connect the second terminal on the brake pedal switch to your controller that needs the +12-volt signal when you step on the pedal. On this second terminal, you will also connect the input wire for the inVERT Mini. The black wire on the inVERT Mini gets connected to ground and the output wire connects to the MASTERCELL input for your brake lights. It’s pretty simple. You can download a PDF copy of this wiring diagram by clicking this link.

Another option is if you have a 4-terminal brake pedal switch. These have two pairs of terminals. Usually, the pair of terminals closest to the switch plunger are the Normally Open contacts. They close when you step on the brake pedal. The set of terminals furthest from the plunger is Normally Closed. These contacts open when you step on the brake lights. These diagrams assume that your switch has a Normally Open and a Normally Closed set of contacts. Please confirm the type of switch that you have by checking resistance between the terminals with a multimeter. You are going to use the Normally Open terminals to ground your MASTERCELL input for the brake lights. Ground one of these terminals and connect the second terminal to the MASTERCELL input.

On the Normally Closed set of terminals, you are going to connect one of these to ground. You then connect one end of a 10K (10,000 ohm) resistor to the second Normally Closed terminal. The other end of the resistor should get connected to the ignition output on your front POWERCELL. This resistor should be rated for at least 1/4 (0.25) Watts. You can buy these easily from Amazon. Just search for “1/4 watt 10k resistor”. This picture will show you the connections that you need to make to your brake pedal switch.

When you are not stepping on the brake pedal, the brake signal wire terminal is pulled to ground by the fact that the terminals are closed. The 10K resistor limits the amount of current flowing through the switch to less than 2 mA (0.002 amps). When you step on the brake pedal, these contacts open and the brake signal wire is pulled up to the battery voltage through the 10K resistor. You can download a PDF copy of this wiring diagram by clicking this link.

There are some scenarios where you need +12 volts when you foot is not on the brake pedal and ground when you step on the pedal. This picture will show you how to wire the switch.

You are going to wire the MASTERCELL input and its ground the same way that you did for the other example. Then connect one of the NC terminals on the switch to the ignition output on your POWERCELL. Connect the second NC terminal on the switch to your brake signal connection. Lastly, connect a 10K resistor (just like in the previous example) between the brake signal wire and ground. When you foot is off the pedal, you’ll have 12-volts on the brake signal wire. When you step on the pedal, the contacts in the switch open and disconnect the brake signal wire from ignition power. The 10K resistor pulls the brake signal wire to ground. You can download a PDF copy of this diagram by clicking this link.

Wiring the Holley HP EFI System

May 20, 2022/0 Comments/in Wiring /by admin

This blog post goes through the details of wiring the Holley HP EFI System with our Infinitybox 20-Circuit Kit. We will show you the ease and simplicity of wiring your EFI system with Infinitybox. The wiring is simple and short and you can eliminate the need for external relays. We’ll go through the key steps and give you a wiring diagram that shows you all the details to wire your Holley HP EFI Engine Management System with our Infinitybox system.

Before we get too far, you must thoroughly read and understand the instructions that came from Holley to install the HP EFI system. Please consult their website to get the instillation instructions. The other important thing to consider here is that we are going to show you how to connect your Infinitybox wiring system to the Holley HP. This will include wiring the key-on ignition power, the cooling fan trigger and the fuel pump trigger. Consult the Holley manual for all details regarding primary power from the battery, coil wiring, injector wiring, sensor wiring and grounds. This diagram shows you the connections between your Infinitybox system and the Holley HP ECU.

Picture of wiring diagram showing how to wire Holley HP EFI system with the Infinitybox wiring system

Your Infinitybox 20-Circuit Kit powers the key electrical systems in your car. We’re going to provide the key-on ignition power to the Holley HP system. You are going to connect your POWERCELL ignition output to the 12V Switched wire in the Holley Harness. This is their Red/White wire. In most Infinitybox configurations, your ignition output is the light-green wire on your front POWERCELL but we encourage you to always use your configuration sheet to confirm wire colors in your specific kit. You can get more details on your configuration sheet by clicking this link. When you turn on your ignition switch, the POWERCELL will provide the key-on ignition power that the Holley HP needs to run. You can learn more about wiring your ignition switch to your MASTERCELL by clicking this link.

You can use an output your Infinitybox rear POWERCELL to provide the power to your fuel pump. There are several advantages to using the fuel pump output on your POWERCELL. First, you do not need to use a relay. The POWERCELL has the capability to control 25-amps to your fuel pump directly without a relay. The second advantage is that you can power the fuel pump from the POWERCELL in the back of your car. This keeps your wiring short and easy to install. The Holley HP ECU has a fuel pump trigger that you can connect into the MASTERCELL input for your fuel pump. The Holley fuel pump signal is +12 volts so you must use one of our inVERT Minis to flip this to a ground trigger to go into the MASTERCELL. You can learn more about the inVERT Mini at this link.

You can also use an output on your Infinitybox front POWERCELL to power your cooling fan. You get same benefits with your cooling fan as you do your fuel pump. Your wiring is shorter and you do not need to use an external relay to control the fan. You can either use a thermostatic switch on the engine or you can have the Holley HP ECU send the MASTERCELL the signal to control the fan. This link will show you how wire in a thermostatic switch. The Holley HP ECU has programmable outputs that can be used to signal the MASTERCELL input for the cooling fan. You need to use one of their “G” or ground switched outputs and need to configure this within their software tool. You must use a diode to isolate the output on the Holley HP from the MASTERCELL. See the details in our wiring diagram.

Those are all of the connections that you need to make between your Infinitybox 20-Circuit Kit and the Holley HP EFI system. You can download a PDF of this wiring diagram by clicking this link.

Haltech ECU Wiring Diagram

February 24, 2022/1 Comment/in Wiring /by admin

Here’s the answer to a question that we get asked a lot. Will the Infinitybox system work with my ECU or EFI system? The answer is always, YES. We play nicely with everyone’s fuel injection system. We recently received this question related to the Haltech Elite 950 ECU. This blog post is going to show you how easy it is to wire this EFI set up with our Infinitybox system.

Just like anything else, please start by reading the instructions. This blog post is going to cover the details of wiring the Haltech Elite 950 ECU with the Infinitybox 20-Circuit Kit. We’re going to assume that you’re running our Front-Engine configuration. If you’re running our Rear-Engine configuration, check your configuration sheet for the specific locations of the inputs and outputs referenced in this blog post. The Haltech part number for this ECU is HT-150700 and you can get to its details at this link. Read and understand their instructions before you get into wiring.

This blog post is going to show you how to get ignition power to their ECU. It will also show you how to take the cooling fan and fuel pump triggers from the ECU into the MASTERCELL. Lastly, this blog post will show you how wire in the power to the injectors and coils so you can eliminate the need for external relays.

This diagram will show you the connections that you will make between your Infinitybox system and the Haltech ECU harness.

Haltech ECU Wiring Diagram with Infinitybox Control

To start, the ECU needs to be grounded. You need to take the black wire going to terminal 10 on the 34-pin connector and ground that. This should be through a metal-to-metal connection to the chassis. There should be no dirt, grease, oil, paint, rust, powder coating or anything else in this connection.

Next, the ECU needs key-on-power. This power should be on when the key is in the run and start position. You are going to get this power from the Ignition output on your POWERCELL. In most kits, this is output 3, the green wire, on the front POWERCELL. Check your configuration sheet for the wire colors for your specific kit. Since your POWERCELLs manage all of the high-current switching in your electrical system, you do not need external relays to control your fuel injection system. Connect your Ignition output from your POWERCELL to the “12V ECU” wire going to terminal 26 on the ECU harness. This is the red wire with the blue tracer.

You can bring ignition power to the coils and the injectors from the Ignition output on your POWERCELL. You can splice these wire together, use a terminal block or use our Splice Saver kit to make a reliable and sealed connection. This diagram will show you how to connect the Splice Saver kit to your ignition output, the coils and the injector.

Infinitybox wiring diagram showing Haltech Key-On Power Wiring Details

Next you are going to connect the outputs on the Haltech ECU for the fuel pump and the cooling fan to their inputs on the MASTERCELL. Haltech dedicates DPO 5 for the fuel pump. You can connect that to your MASTERCELL Input for your fuel pump. We strongly recommend isolating the MASTERCELL from the ECU with a 1N4001 diode. The orientation of this diode is very important. Refer to the diagram above to show proper orientation of the anode and cathode of this diode.

You can use any of the other digital outputs on the Haltech ECU to trigger the MASTERCELL input for the cooling fan. You must isolate the ECU from the MASTERCELL using a 1N4001 diode like the fuel pump. We chose DPO 2 in our diagram. You can use any of the available digital outputs however you must set them up correctly in their programming application.

Please note that you cannot pulse the DPO signal from the ECU that goes into the MASTERCELL for the fuel pump or the cooling fan. These should be on and off signals to turn the pump and fan on and off.

Reverse Lockout Solenoid

September 25, 2021/0 Comments/in Wiring /by admin

A customer just sent us pictures showing how he wired a switch into his transmission shifter to control his reverse lockout solenoid. He wanted to make sure that he couldn’t accidentally shift into reverse when he was in the upper gears. By using our Infinitybox wiring system, he was able to easily control this solenoid.

Ed K. is building a 1968 Pro-Touring Mustang fastback. He has transplanted a Coyote engine from a 2014 Mustang and mated it to a Tremec T56 6 speed transmission, feeding a Ford 9 inch rear end for the drivetrain. He is using our 20-Circuit Kit with inLINK, inRESERVE and inMOTION to wire his car.

The Tremec transmission is outfitted with a solenoid lockout feature that further pre-loads an already compressed spring acting on the shift gate to prevent accidentally engaging reverse while downshifting from 6th gear to 5th gear, which would be catastrophic. In order to engage reverse, when desired, this solenoid must be energized to remove this extra spring pre-load. Typically, this solenoid is energized by a body controller when the car is moving at 5 miles per hour or less to allow a shift into reverse. Ed wanted a simpler way to engage this reverse lockout solenoid in his 1968 Mustang.

Ed modified the shift lever to add a microswitch to it. When he pulls up on the shifter handle, the switch closes. He can use this switch to control his reverse lockout solenoid.

Ed picked the OPEN output on his front POWERCELL to power his reverse lockout solenoid. The OPEN outputs on your configuration sheet can be used for practically anything. They are auxiliary outputs for any additional electrical accessories that you may have on your car. Click on this link to learn more about OPEN outputs.

Ed connected this open POWERCELL output wire to the solenoid, then grounded the other side of the solenoid wiring.

Next, Ed found the MASTERCELL input that corresponds to the OPEN output that he used. Your configuration sheet shows you which input and output wire colors go together. Ed connected this MASTERCELL input to the normally open terminal on his shifter switch. Then he connected the common terminal of the switch to ground. When he pulls up on the reverse handle, the switch closes. This connects the MASTERCELL input to ground. The MASTERCELL sends a command to the front POWERCELL to turn on the output, which energizes the reverse lockout solenoid. This pulls back the reverse gate, which lets him shift into reverse. Here is a simple wiring diagram showing how this was connected.

Ed was able to wire his reverse lockout solenoid easily with our Infinitybox system. He didn’t have to add any relays to his car to do this. He was able to use the flexibility and expandability of our system to get what he needed in his car.

Race Car Replicas SL-C Steering Column Wiring

May 11, 2021/0 Comments/in Wiring /by admin

This blog post is going to give you the details for wiring the steering column connector on your Race Car Replicas Superlite Coupe. Fran and his team at RCR have been engineering and manufacturing one of the highest performance and most complete kits to build super cars. Their chassis are engineered to perfection, the body styling is top notch and they give you everything that you need to build you own masterpiece.

They include a General Motors steering column with each kit. This post and wiring diagram are specific to the Oldsmobile column. If you have the older Cadillac steering column with power tilt & telescoping, give our team a call for specifics on the wiring

There is a connector on the Oldsmobile column that interfaces with the multi-function turn signal stalk. This has the signals for the parking lights, head lights, high-beams and turn signals. The connections between the steering column connector and the inputs on your MASTERCELL are simple. Here are the details.

First, you need to have a good way to make the connection between our MASTERCELL inputs and the wires going to the steering column. You could cut off the connector on the column and splice these wires together. We recommend a much easier way. You can purchase the mating connector and terminals to make this connection. You can purchase these components from Mouser. These parts are made by Aptiv, formerly Delphi. The part number for the connector is 12092248 and the terminals is 12092345. You will need 9 terminals.

You will need to splice the MASTERCELL input wires for your grounds, turn signals, parking lights, head lights and high beams to these terminals and insert them into the corresponding cavities on the mating connector. The cavity letters are molded into the plastic on the side of the connector. For your grounds, you can use the black ground wires in the MASTERCELL input harness. This list shows you which wire colors correspond to the different mating connector cavities.

Grounds- Black Wire- Cavities D, Q, X & Z

Right Turn Signal- Yellow/Red Wire- Cavity F

Left Turn Signal- Yellow/Black Wire- Cavity G

High-Beam- Blue/Red Wire- Cavity K

Head Light- White/Green Wire- Cavity L

Parking Lights- Blue/Black- Cavity R

It is also important that you install a diode between the inputs for the head lights and high-beams. This should be a 1N4001 diode which can be purchased from Amazon or any other on-line electronics store. The orientation of this diode is very important. The cathode or the stripe on the diode must be connected to the high-beam input going to the MASTERCELL. This is the blue/red wire going into cavity K. You can crimp the leads of this diode to the terminals with the MASTERCELL wires to make this easier.

That is all you need to know to connect your MASTERCELL input wires to your steering column connector for your Race Car Replicas SL-C.
