Wiring the Holley HP EFI System

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.

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

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

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.

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.

System Current Draw

When you wire your car or truck with our Infinitybox system, you are adding a powerful electrical management system to your build.  We do so much more than a traditional wiring harness.  Our system has the power and intelligence to get you modern electrical control of your muscle car, restoration, street-rod, hot-rod, resto-mod, pro-touring car or race car.  Your Infinitybox system is awake and alive continuously so that it can respond immediately when you want to start the car, pop your trunk from our inLINK key fobs or control the system from your smart phone.

Wiring your car with the Infinitybox system gets you features that you cannot get from any traditional wiring harness but it does require more care & feeding.  Our system does have a parasitic draw on your battery when the car is sitting idle.  This is different than a traditional box of fuses and relays that has no active electronics in it.  We strongly recommend that you have a way to manage your battery for when you are not driving your car or truck.  There are three ways you can do this.

First, we always recommend a disconnect switch at the battery.  This is a quick and reliable way to disconnect the battery from your car’s electrical system.  This is a good idea for any car, even if you are not using the Infinitybox system to wire your car.  Other electronics systems that you add to your car, like electronic fuel injection systems, stereo equipment, will have parasitic draws from the battery.  A disconnect will help to keep your battery voltage up when you’re not driving the car.

Second, we always recommend some kind of trickle charger or maintainer for your battery for when your car is sitting idle.  This is true for any car, not just cars wired with our Infinitybox system.  You have many options for maintainer chargers from brands like Battery Tender, CTEK  and Schumacher.  Battery maintainers keep your battery voltage at its optimum level when the car is idle.  This will dramatically increase the life and reliability of your battery.

Lastly, our Infinitybox system has a unique accessory called inRESERVE.  inRESERVE is our active battery management feature.  The core of inRESERVE is a special latching solenoid that connects to a POWERCELL output.  The Infinitybox system is always watching and monitoring the battery voltage.  If the system sees the voltage start to get low, the POWERCELL sends a pulse to the special inRESERVE solenoid and disconnects all of the drain from the battery.  We build a lot of safety features into this system.  inRESERVE actively does its job if the battery drops below 12.3 volts, with the ignition off and stays at that level for 15 minutes.  This video talks through inRESERVE in more detail.

inRESERVE also gets you the disconnect feature that we mentioned in our first point above.  You can simply press the button included with your inRESERVE kit to disconnect the battery.  This adds a great security feature and lets you shut down power if the car is going to be sitting for extended periods of time.

We get a lot of questions about how much current the different components in the Infinitybox system draw when idle.  The MASTERCELL, POWERCELL and inMOTION cell each draw approximately 30 milliamps (0.03 amps) when they are powered up.  Adding the inLINK option adds approximately 10 milliamps to the MASTERCELL draw.  inVIRONMENT is in the range of 25 milliamps.  inTOUCH NET will draw 200 to 250 milliamps.

Please contact our team with any questions about the idle current draw of our Infinitybox system.  You can call us directly at (847) 232-1991 or you can click here to contact our team directly.

 

Jeep CJ7 Wiring Series- POWERCELL Locations

Over the next few videos, we’re going to continue our theme on good planning.  Specifically, we’re going to talk about picking the best locations for the major components that come with your Infinitybox system.  We’re installing our 20-Circuit Kit with inLINK and inRESERVE in our 1979 CJ7.  To get the most out of our install, we want to pick the best locations for the MASTERCELL, the front & rear POWERCELLs, the MEGA fuse holder and the inRESERVE solenoid.  We’ve broken this up into 5 different videos, talking about what you need to consider for each part.  This video covers picking the best locations for your front & rear POWERCELLs.

Side View of the Infinitybox POWERCELL

Side View of the Infinitybox POWERCELL

You get two POWERCELLs in your 20-Circuit Kit.  One for the front of your car and one for the rear.  The POWERCELLs are the remote fuse & relay boxes for your system.  They get commands sent to them from the MASTERCELL and they do the actual switching for all of your lights, ignition, starter, fuel pump, cooling fan, horn and other accessories.  You can learn more about the POWERCELL by clicking this link.

There are two important things to consider when you’re picking the best locations for your POWERCELLs.  First, you want the POWERCELLs as close to your electrical loads as possible.  This keeps the wiring short and makes it easy to install.  Your front POWERCELL is going to power your headlights, high-beams, turn signals, parking lights, ignition, starter, horn and dash.  You want to keep the front POWERCELL close to these loads to keep the wiring short.  Your rear POWERCELL is going to power your brake lights, turn signals, reverse lights, running lights, fuel pump and any audio that you have in the back of your car.

The other thing to consider when you pick your POWERCELL locations is that your POWERCELLs are the remote fuse boxes.  You need to have reasonable access to the POWERCELL to remove the protective cover and change the fuses.

In our 1979 Jeep CJ7, we’re going to mount the front POWERCELL on the inner driver’s fender.  There is a nice flat spot there to make mounting easy.  It is accessible for maintenance.  The 8-AWG power cables can be easily routed across the firewall to connect to the battery and the runs of wires to the loads are all relatively short.  Check out more detail on the location in this video.

We’re going to mount the front POWERCELL inside the rear passenger fender.  We will fabricate an enclosure inside the fender that is outside the travel for the suspension.  We’ll make a sealed cover over the enclosure so we can get to it easily for maintenance.  We can easily run the 8-AWG power feeds and the CAN cable down the passenger side of the Jeep.  Finally, the runs of wires to the brake lights, turn signals, running lights, reverse lights and fuel pump are all relatively short.  Check out more detail on the location in this video.

We created this simple diagram to show the POWERCELL locations in the Jeep plus the primary power cables from the battery, through the inRESERVE solenoid and through the Mega fuse holders.  You can download a PDF copy of this diagram by clicking this link.

Infinitybox CAD Models

Our customers are a unique breed of builder and fabricator.  They wire their cars and trucks with our Infinitybox system for a lot of different reasons.  To start, our system lets them simplify their wiring.  More importantly, our customers want more than just a plain, basic electrical system.  They want the same electrical features in their project that they have in their new, daily driver.  Our Infinitybox system lets them do that.  Since our customers are tinkers, makers and builders, they are using the latest solid modeling technology to virtually mock up their cars and trucks to make the project go more smoothly.  We get a lot of requests for CAD models for our cells, so we’ve made them available to our customers.

The introduction of on-line CAD tools like Audodesk’s Fusion 360 gives anyone in their garage access to very powerful and intuitive solid modeling tools.  You can import the CAD models for the Infinitybox MASTERCELLPOWERCELL and inMOTION cells into your projects.  You can check fitment, verify wire routing and make sure that you can access the cells, all in the computer before you cut any metal.

We have the solid models for the MASTERCELL, POWERCELL and inMOTION cells available in STEP and IGES formats.  Click on this link to contact our technical support team and we will send you the models.

Setting Infinitybox Address Jumpers

Our Infinitybox system is very flexible.  You can scale it from a very simple wiring system to one that is very complicated.  Our standard 20-Circuit Kit includes one MASTERCELL and two POWERCELLs.  You can add more POWERCELLs to expand the number of outputs in your system.  Every POWERCELL you add gives you 10 more outputs.  You can also add the inMOTION cell to control things like your power windows and power locks.  For all of these cells to work correctly on our Infinitybox CAN network, they each need their own address.  This is a unique name given to each cell so that it knows who it is and what commands it should listen to.  This blog post is going to go through setting the Infinitybox address jumpers.

There are address jumpers located under the clear covers of the POWERCELL and the inMOTION cell.  Setting the Infinitybox address jumpers is done in exactly the same way for both the POWERCELL and inMOTION.  The following illustration shows where the address jumpers are located under the POWERCELL cover.

POWERCELL Address Settings

POWERCELL Address Settings

The cells use BCD to set their address.  With BCD, you can use a small number of pins to set a large number of options.  In the case of our POWERCELLs and inMOTION cells, there are 4 sets of pins.  Each of these pins has a numerical value.  Going from left to right, these pins are 1, 2, 4 and 8.  When the cell power up, it looks at those pins to get its address.  It adds up the value of the pins that do not have a jumper on them.  For example, if there was no jumper on the first set of pins, that would be a value of 1.  If there was no number on the second set of pins, that would be a value of 2.  If there were no jumpers on the first and second set of pins, that would be a value of 3 (1 + 2).  The follow illustration shows the combinations of jumpers to get the most popular addresses used with our Infinitybox system.

How to set the address jumpers on the Infinitybox POWERCELL

How to set the address jumpers on the Infinitybox POWERCELL

In all standard 20-Circuit Kits.  The front POWERCELL is addressed as 1 and the rear POWERCELL is addressed as 2.  If you add inMOTION, that is addressed as 3.

The cells only learn their address the instant they are powered up.  If you change the address while the system is powered up, the cells will not change their address.  You should disconnect power from the system before you change any address headers.

When you are first setting up your 20-Circuit Kit.  You need to make sure that you have the POWERCELL jumpers set to the correct addresses for their location in your car.

1955 Chevy Bel Air: Great 8 Winner at 2020 Detroit Autorama from eclassicautos on Vimeo.

Bob’s team started with our Infinitybox 20-Circuit Kit to wire the car.  From there, they added inMOTION to control their power locks and power windows.  They added inLINK for remote control from a key fob.  inRESERVE for active battery management.  inTOUCH NET so they can control the car from a tablet or smart phone.  And inVIRONMENT so they can control their Vintage Air Gen-IV from their touch screen.  They have the cells strategically located in the car to optimize the wiring harness and get them the most features.

We had a chance to talk to Chris Brown of Brown Auto Design at the Autorama.  Chris is the mastermind behind the design of this car.  He mentioned to us that he had very limited room to run wires in the car.  Using the Infinitybox system made wiring the car much easier for him and his team.
