The Dakota Digital PAC-2800BT

Dakota Digital PAC-2800BT Cooling Fan Controller

This blog post is going to show you how to use the Dakota Digital PAC-2800BT to control your cooling fan with the Infinitybox system.  The PAC-2800BT is a powerful controller that lets you program the temperatures that turn on and turn off your cooling fans.  You have the flexibility to use any temperature sender, take in OBDII data from a modern ECU, even interface with the VHX & RTX gauges.  We’ve blogged before about wiring the VHX and RTX gauges with the Infinitybox system.  Click on the links to learn more.

There are multiple advantages to using the Infinitybox system with the Dakota Digital PAC-2800BT controller.  First, you can eliminate the external relay and the fuse.  These are built into the POWERCELL.  Next, you can streamline your wiring.  The PAC-2800BT would be located behind your dash, near the MASTERCELL.  The power for the fans comes from the front POWERCELL, which is located strategically where you need it in the car.  Lastly, the POWERCELL has the ability to soft-start the cooling fan.  This decreases the in-rush current to the fan and lets you drive a larger fan with a smaller gauge of wire.  You can read more about this at this link.

As always, we strongly encourage you to read and understand the manuals for anything that you are installing in your car.  Dakota Digital has a very detailed manual for the PAC-2800BT.  You can access it by clicking this link.  Also, this blog post is going to cover the wiring between the Infinitybox system and the PAC-2800BT.  This includes ignition power, the cooling fan triggers to the MASTERCELL and the cooling fan output from the POWERCELL.  Follow the Dakota Digital instructions for wiring battery power, ground, the temperature sender and the other optional features of the PAC-2800BT.

The following picture shows the connections between the Infinitybox MASTERCELL and the POWERCELL for the PAC-2800BT.

First, you need to get ignition or key-on  power to the PAC-2800BT.  This is going to come from the POWERCELL output for the ignition.  This is output 3, the light-green wire on the front POWERCELL in most systems, .  Please check your specific configuration sheet to confirm.  You can going to bring this ignition power to the IGNITION terminal on the PAC-2800BT module.  You are going to tap off your POWERCELL ignition output to get this power.  You can splice into this wire or you can use our Splice Saver kit to create an ignition junction point.

Next, you are going to connect your MASTERCELL cooling fan inputs to the triggers on the PAC-2800BT.  In most systems, your cooling fan is input 10, which is the blue wire with the green tracer.  Check your configuration sheet to confirm.  If you are using only one cooling fan, Dakota Digital tells you to use the FAN LOW terminal on the PAC-2800BT.  We strongly recommend that you install a diode in-line between the MASTERCELL and the PAC-2800BT.  This should be a 1N4001 diode that can be purchased easily from Amazon.  The orientation of this diode is critical and the system will not work correctly if it is wired backwards.  The diode lead on the side with the stripe should be connected to the PAC-2800BT.

Lastly, you are going to connect your POWERCELL output for the cooling fan to the wires on the fan motor.  The other wire on the fan motor should be connected to a good chassis ground.   This link will get you more details on wiring the cooling fan with the POWERCELL output.

The PAC-2800BT gives you the option to control two separate cooling fans.  If you want to use a second cooling fan, you would simply repeat wiring an unused MASTERCELL input to the PAC-2800BT and an OPEN POWERCELL output to your second cooling fan.  In most of our kits, output 8 on the front POWERCELL can be used as an auxiliary output.  You can use this one to power your second cooling fan.  See your specific configuration sheet for more details.

Here is how all of this works.  The PAC-2800BT takes in the temperature data from the temperature sender, the Dakota Digital gauge controller or the ECU via OBDII.  If the temperature it reads goes higher than the value that you programmed in it, it grounds the MASTERCELL input for the cooling fan.  This turns on the cooling fan input.  The MASTERCELL sends a command to the POWERCELL in the front of the car to turn on the output for the cooling fan.  When the temperature drops below the set point that you programmed in the PAC-2800BT, it turns off the MASTERCELL input for the cooling fan.  The MASTERCELL sends a command to the front POWERCELL to turn off the fan.  It is that easy.

If you choose the option to use two cooling fans, the PAC-2800BT will manage both fans together to control the engine temperature.

Wiring Dakota Digital RTX Gauges

Dakota Digital has been in the business of making advanced electrical products for the Automotive Aftermarket for a long time.  Their products include gauges, lighting, cruise control systems, gear indicators, linear actuators, climate control interfaces and other automotive accessories.  We’ve posted details before on how to wire their automatic door lock controller and their VHX series of gauges. They recently introduced their RTX gauge family.  These bring classic styling with modern features to any hot-rod, street rod, resto-mod or Pro-Touring build.  This blog post is going to walk you through the details of Wiring Dakota Digital RTX Gauges to our system.

Before we go too far, this post is only going to cover wiring primary power, ground, key-on power, gauge lighting and the signals for the indicators on the dash.  Their manual will cover the details for the rest of the wiring.  Carefully read and understand all of the details of the RTX instructions before you go any further.  You can get their manual by clicking this link.

This diagram shows an overview of the connections to the Infinitybox system for the RTX controller box.

Their RTX controller needs constant power from the battery.  Connect the 12 VDC CONSTANT terminal on their controller box directly to the positive terminal on the battery.  You must fuse this wire at the battery for safety.  You also have to connect the GROUND terminal on their controller box to a good chassis ground connection.  This must be a metal-to-metal connection that is free of paint, powder coating, dirt and debris.

Here are the connections that are specific to the Infinitybox system.

First, the RTX controller box needs ignition or key-on power.  This is what turns the gauges on when you turn the key in the car.  Your ignition output is going to provide this power.  In most systems, this output is number 3 on the front POWERCELL.  Check the configuration sheet that came with your kit to confirm.  This ignition output is going to power your engine management.  You are going to splice into this wire to connect to the IGNITION PWR terminal on the RTX controller box.  You can manage this splice a few different ways but our Infinitybox Splice Saver Kit is a great way to create a sealed junction point for everything in your car that requires ignition power.

Next, you need to connect your parking light output on the front POWERCELL to the DIM terminal on the RTX controller box.  This will turn on the illumination on the RTX gauges when you have your parking or headlights on.  Just like the ignition output, splice into the parking light output on your front POWERCELL and connect this to the DIM terminal.

Next you need to connect your dome light output to the EX terminal in the DOME INPUT section of their RTX controller.  You can use any of the OPEN outputs on your POWERCELLs as your dome light output.  This blog post will get you more detail on wiring your dome lights and pin switches on your 20-Circuit Kit.

Lastly, you need to connect the POWERCELL outputs for your turn signals and high-beam to their respective terminals on the RTX control box for the turn signal indicators and high beam indicators.  Just like the key-on power and parking lights, splice into the output wires for the left turn signal, right turn signal and high-beams and connect them to the LEFT, RIGHT and HIGH terminals, respectively.  When your POWERCELL is flashing the left turn signal, the indicator for the left turn signal will flash on the Dakota Digital gauges.  When you have your high beams on, your high beam indicator will light up on the gauges.

Our Infinitybox system can power any electrical system in your resto-mod, street rod, pro-touring build or race car.  Wiring Dakota Digital RTX Gauges is a great example of that.  You can download a PDF of this wiring diagram by clicking this link.

PAC-3500

The Infinitybox Intelligent wiring system can easily interface with any other electronics modules sold into the restoration and motorsports markets. By pairing our system with other popular accessories, you can enhance the features and functions of your resto mod, Pro-Touring build, street rod or race car. We had a customer call us today asking how he could get a speed sensitive electrical function on his car. This blog post covers that in detail.

This guy built a custom license plate holder for the back of his car. It has an electrically operated linear actuator and he’s using our inMOTION motor controller to raise and lower his license plate. He has one pair of inMOTION outputs wired to the linear actuator. He wants his license plate to be lowered when the car is moving and raise when the car stops. He wants to use this only for car shows and not when he is driving the car on the road.

He called us asking how he could get this speed sensitive control with our Infinitybox system. We recommended adding the Dakota Digital PAC-3500 Automatic Door Lock Controller to his system to get this to work. The PAC-3500 takes in the signal from his speedometer sender and uses that to control a lock and unlock input. When the vehicle is moving and the PAC-3500 is getting a speed signal, the module sends out a trigger on one wire. When the vehicle stops moving, the module sends out a signal on a different trigger wire. With the PAC-3500, our customer can easily switch his MASTERCELL inputs to lower his license plate when the car is moving and raise it when the car stops. This diagram shows how to wire the PAC-3500 to the Infinitybox System.

The PAC-3500 needs fused constant power from the battery and a connection to the chassis to ground. It also needs a ignition signal which would come from the ignition output on your POWERCELL. Next, you connect the SPD terminal on the PAC-3500 to the output from your speed sender. Lastly, you connect your MASTERCELL inputs to the LOCK and UNLOCK terminals on the PAC-3500. You must isolate the MASTERCELL from the PAC-3500 using diodes. We recommend a 1N4001 diode. The orientation of these diodes is critical so note their orientation in the wiring diagram.

Whatever MASTERCELL input that you have connected to the LOCK terminal on the PAC-3500 will turn on when the vehicle is moving. Whatever MASTERCELL input that you have connected to the UNLOCK terminal will turn on when the car stops moving. You can set the vehicle speed that turns these on and off by following the instructions in the manual from Dakota Digital. This link will take you to the manual for the PAC-3500.

With the PAC-3500 and our Infinitybox system, you can get speed sensitive control of your electrical system. Raising and lowering this license plate is just one example. You could also use this to lock and unlock your doors with our inMOTION cell. We could set your system to turn off power to your electrical power steering assist above a specific speed. We could use this to raise a wing on the back of the car when you exceed a specific speed. Your options are limitless.
