The VaporWorx Fuel Pump Controller

Wiring VaporWorx Fuel Pump Controller

We always say that our Infinitybox system plays nicely with other electrical accessories in your car.  This blog post is another great example of that.  We got a call from a customer asking about wiring the VaporWorx Fuel Pump Controller with his Infinitybox 20-Circuit Kit.  He was worried about having to wire in additional relays and run a lot of wire.  In reality, wiring the VaporWorx Fuel Pump Controller is simple and easy with the Infinitybox system.

The VaporWorx guys make some very cool products.  Click here to get to their website.  You have to appreciate a company with the tagline “We Give You Gas”.  Their core products improve the delivery of fuel in your resto-mod, street rod, hot-rod or Pro-Touring build.  They have been innovating products for reliable fuel delivery in cars with EFI systems since 2009.

Their core products are designed for returnless fuel systems.  There is only one fuel line going from the in-tank pump to your fuel rail.  There is no fuel regulator on the rail and no return line that brings excess fuel back to the tank.  Their Fuel Pump Controller mounts in the rear of the car, near the fuel pump.  It actively monitors the fuel pressure in the line at the outlet of the pump.  Using pulse-width modulation (PWM), they vary the pump power to keep the fuel pressure within a tight window.  This reduces dead-heading of the fuel pump and also reduces the amount that the fuel gets heated.  We use PWM to control things like fan speed and light dimming from our POWERCELLs and have blogged about how that works before.  Click on this link to learn more about PWM.

This blog post is going to walk you through wiring the VaporWorx fuel pump controller with our Infinitybox system.  We are only going to cover the connections from the battery, from the POWERCELL and to ground.  See their manual for more details on the rest of the sensor wiring required for their controller.  You can access the manuals and installation instructions for their products by clicking this link.

Just like any other blog post where we talk about integrating the Infinitybox system with other products, please carefully read and understand all of the steps required to install the VaporWorx Fuel Pump Controller.  You are messing with flammable fuel and electricity.  Make sure you are completely comfortable with doing this job.

For the sake of this blog post, there are three connections that we are going to cover: primary power from the battery, the fuel pump trigger from the POWERCELL and the grounds.

The primary power for the fuel pump controller is going to come directly from the battery.  This should be a simple connection since the controller should be mounted close to the pump in the tank and most guys are relocating their batteries to their trunks.  Follow the recommendations from VaporWorx for the gauge of wire going from the positive terminal on the battery to the BAT+ terminal on their module.  It is very important that this gauge of wire is sized correctly and that it is fused as close to the battery as possible.

Next, the fuel pump controller and the fuel pump need to be grounded.  The VaporWorx team recommends that you ground their pump controller and the fuel pump directly to the negative terminal of the battery.  This should be easy in most installs since guys are relocating the batteries to their trunks.

Last, the VaporWorx controller needs a fuel pump enable signal from the ECU.  When wired with the Infinitybox system, this signal is going to come from the fuel pump output on your rear POWERCELL.  In most 20-Circuit Kits, this is the TAN wire on the rear POWERCELL but check your configuration sheet for details on this output.  The POWERCELL output is going to connect to the blue wire in the GT150 connector.

The advantage of using the POWERCELL to supply the fuel pump enable signal is that you do not need to add any additional wiring.  You already have the POWERCELL located in the rear of your car.  You do not need to run a wire from the front of the car to the back.  You can simply use the POWERCELL to supply this signal.

Once you have power, ground and the fuel pump enable signal wired, you need to wire your EFI system to your Infinitybox MASTERCELL.  This is how the POWERCELL knows when to turn on the output for the fuel pump enable signal.  To do this properly, you need to understand if your EFI system uses a ground trigger for the fuel pump or a positive signal for the fuel pump.  The wiring diagram for your EFI system will define this.  Alternately, we have wiring diagrams for all of the popular EFI systems in the Resources section of our website.

If your EFI system sends a ground trigger for the fuel pump enable signal, you can wire the MASTERCELL fuel pump input to the EFI system’s fuel pump output.  We strongly recommend wiring a diode in series to buffer the MASTERCELL from the ECU.  As an example, the FAST XFI 2.0 sends a ground trigger for the fuel pump enable signal.  You can see how the recommended diode is wired at this link.

If your EFI system sends a positive trigger for the fuel pump enable signal, you need to flip this to a ground trigger.  You can use one of our inVERT Mini Buffers to do this easily.  The Holley Sniper EFI System uses a positive trigger for the fuel pump enable signal.  You can see how to wire in the inVERT Mini at this link.

This wiring diagram shows you all of the connections between our Infinitybox system and the VaporWorx Fuel Pump Controller.  You can download a PDF version of it by clicking this link.

inMOTION Video

We just released a new video that covers the features and benefits of our inMOTION Motor Controller Cell.

Infinitybox inMOTION Motor Controller Cell

inMOTION is a unique module that connects to the CAN network of your 20-Circuit Kit.  It looks like a POWERCELL but acts differently.  Instead of turning 10 things on and off like a POWERCELL, it reverses the polarity to 5 things.  We originally designed inMOTION to control power windows and power lock actuators.  Instead of relying on a switch, inMOTION has special h-bridge relays that reverse the polarity.  This lets you change direction of things like power windows, power locks, linear actuators and valves.

That is just the beginning.  inMOTION is smarter than a POWERCELL which means that you can get express features on your windows with no limit switches.  You can also get wireless control through inLINK or a smart phone attached to inTOUCH NET.

Check out this video for a deeper dive into what inMOTION can do.

We have the solid model for the inMOTION cell available to our customers to help with their planning and mocking up process.  Click on this link to get more details.

1970 Mustang Wired with the Infinitybox System

1970 Mustang Infinitybox Wiring

Here’s another great example of a customer car wired with our Infinitybox system.  Paul L. wired this beautiful 1970 Mustang with our 20-Circuit Kit, inLINK and inMOTION.  Paul just sent us pictures showing off the finished car and how he installed his Infinitybox system.

This picture shows the center console of his car.  You can see the MASTERCELL and the inMOTION cell located in the frame of the center console.  The MASTERCELL connects to all of his switches.  The inMOTION cell controls the motion of his power windows and door locks.

He relocated the battery to the trunk of the car.  He used this space for his ignition system and his front POWERCELL.  This POWERCELL location is great because it makes most of his front wiring short and easy to install.  His headlights, high-beams, turn signals, running lights, starter solenoid, ignition power, cooling fan and horn are all powered from this location.

His rear POWERCELL is located in the trunk.  This makes wiring his brake lights, turn signals, rear running lights, fuel pump, trunk popper and other accessories very easy.

We did some simple customization of this code to get him extra features.  He’s controlling his door locks from outputs on inMOTION.  His doors lock and unlock when he enables and disables security from his inLINK key fob.  He is also using a POWERCELL output to operate a solenoid to pop his trunk.  We programmed a button on his inLINK key fob to pop the trunk.  He also wanted an output on his rear POWERCELL to turn on with ignition.  These are all very simple changes to our system.

The finished wiring is simple and elegant.  We thank Paul L. for sending these pictures.  We’re proud to be a part of his project.

Fingernail for 2019 Infinitybox Introductory Video

Infinitybox Introductory Video

Infinitybox is excited to announce a new series of videos going through the details of our Infinitybox system.  We’ve shot them in a very simple and effective way to get the point across.  Jay Harris, the president of Infinitybox, will take you through every piece of our system.  He will also walk you through the process to wire your car with our Infinitybox system.

In this introductory video, Jay describes how our Infinitybox system works and how it is different from traditional wiring harnesses.  Until Infinitybox came onto the scene in 2009, little had changed in the way you wire a car since the Model T.  Our system revolutionized the way restorations, kit cars, resto-mods, street rods, hot rods, race cars and Pro-Touring cars were wired.  Instead of a single, central box of fuses and relays, the Infinitybox gives you separate modules that you put in the car where you need them.  The separate Infinitybox modules are connected with a simple and thin data cable.  You can watch the introductory video here.


This is the first video in the series.  There are more coming that go through each of our specific products.  Be sure to subscribe to our YouTube channel Infinityboxllc and click on the bell icon to get notified when we post new videos.
