Wiring any switch into the Infinitybox system is really easy. You just have to remember that the MASTERCELL input wire needs to get connected to ground to turn something on. In most cases, you can simply connect the MASTERCELL input to one side of the switch and ground the other. When you close the switch, the MASTERCELL input gets connected to ground and the output turns on.
With most OEM switches and the original switches that are in your car, you can connect the battery feed from the switch to ground. Then you connect the MASTERCELL input wire to the terminal on the switch that powered the original function. Here’s a good example for a GM Ignition Switch. This GM Ignition Switch was used in most Chevrolet and Pontiac cars from 1969 through 1994.
You connect the original battery feeds for the GM ignition switch to ground. You then connect the MASTERCELL intput wires for the ignition and starter to their respective terminals on the switch. When you turn the key to the ignition position, the switch connects the MASTERCELL input wire for the ignition to the ground through the battery terminal. This sends a signal to the POWERCELL to turn on the ignition output. The same thing happens when you turn the key to the starter position. We created a simple wiring diagram showing you how to wire this GM ignition switch.
