Here’s where we are in our project installing our Infinitybox system in a 1967 Mustang. We mounted our primary fuses, ran power to the battery, mounted the MASTERCELL and POWERCELLs, ran power to the POWERCELLs and routed the CAN cable through the car. Now it is time to start wiring inputs to the MASTERCELL from your switches and connecting the outputs from the POWERCELL. Before you get too far, let’s talk about the Configuration Sheet that comes with your kit.
The Configuration Sheet is your roadmap to wiring the car. Tells you the wire colors that connect to your switches and to your switched outputs. This is a really important document so let’s spend a few minutes reviewing it.
All of the MASTERCELL input wires and POWERCELL output wires are color coded. The same is true for the inMOTION output harnesses. You are going to use the Configuration Sheet to pair these input and output wires to their switches and the outputs.
Depending on the kit that you ordered and the accessories that you have, your configuration sheet is going to be unique to your system. Likewise, if we did custom programing for your system, you’ll have a configuration sheet that is specific to you. We also have different configuration sheets for where the engine is located in the car. The Front-Engine configuration is our most common and is probably the most self-explanatory. This is used for cars where the engine is in the front of the car. The outputs for the ignition and starter are on the front POWERCELL.
If you are building a mid-engine or rear-engine car, you’d use the Rear-Engine configuration. The outputs for the ignition and starter are on the rear POWERCELL.
We also have specific configurations for component cars made by Factory Five. These include kits specifically configured for the Hot Rod, the GTM and the 818. These are based on things that we have learned from hundreds of systems that we sold into guys building these cars. If you’re building the MK4 Roadster or the Type 65 Coupe, you’d use the standard Front-Engine configuration.

Let’s take a look at an example. This picture from a configuration sheet showing the details for the Headlights. Click on this image to blow it up to see the detail.
The first column is Function. This describes what is being controlled. You’ll see that there are rows for your ignition, starter solenoid, head lights, parking lights, high-beams, horn, cooling fan, turn signals, 4-ways and brake lights. There are also rows that marked as OPEN. These are generic and can be used for any other accessory that you have in your car.
The next column is Switch Input. This is the number that we use to identify the MASTERCELL inputs. There are 48 inputs on a MASTERCELL. Please note that the input number does not line up with the cavity marking on the input connectors. Click on this link to get a document that connects the MASTERCELL input number to the cavity marking on the connector. The MASTERCELL input wires are going to connect to the switches in your car. We’ll talk about that in a later post.
The next column is MASTERCELL Connector. There are two input connectors for a MASTERCELL, each has 24 inputs. The majority of your inputs will be on the A connector which plugs in the socket above the MASTERCELL screen. For systems with accessories like inMOTION and additional POWERCELLs, you will be using the B connector which is located below the MASTERCELL screen. Some kits do not come with this MASTERCELL B harness.
The next column is POWERCELL Address. This tells you which POWERCELL has the output that will turn on with that input. In the case of our headlight example, the POWERCELL address is 1. This means that the headlight output is on the front POWERCELL. You will see that there are some rows with POWERCELL address that say 1:2. This means that outputs on both POWERCELL 1 and POWERCELL 2 will turn on with this input. Examples include parking lights, turn signals and 4-ways.
The next column is POWERCELL Connector. Just like the MASTERCELL, there is an A & B output connector on the POWERCELLs. In the case of our headlight example, the headlight output is on the B POWERCELL connector. Your manual will show you which output harness plugs into which socket on the POWERCELL.
Next you get the Personality column. This describes how the output will act when the input is turned on. This separate blog post will get you more information on output personalities. Click here to see it. In the case of the headlight example, the output will track the input and it will soft-start.
Next you get the POWERCELL Output column. This describes the number of the output on the POWERCELL that is turned on with the input on that row. For our headlights, that is output number 5.
The last two columns are the most important and most practical. Ignoring everything to the left, these two columns tell you the MASTERCELL input wire color and the POWERCELL output wire color. For the headlights, you are going to connect the White wire with the Green tracer to the headlight switch. You are going then take the White wire from the POWERCELL and connect that to your headlights. When you turn on the headlight switch, the White-Green wire will get grounded by the switch. The MASTERCELL sees this input turn. It sends a command to the POWERCELL to turn on the headlight output. This is the white wire.
This is one of the areas where our Infinitybox system is dramatically different from a traditional wiring harness. Your switches connect to the MASTERCELL. Your lights, fans, pumps, ECU’s, starter solenoid and other outputs connect to the POWERCELL.
There is a video on our YouTube channel that goes through the configuration sheet in more detail. You can catch this video below.
