How to Wire a Headlight Switch to the ISIS MASTERCELL...

Okay... here's another ISIS wiring example. It's hot off the press.

A lot of guys ask how to wire the headlight switch into the inputs on the ISIS MASTERCELL. It is pretty easy. Check out the application note here.



One of the biggest things that you will notice here is how small the wires are going to the switch. ISIS works differently from a traditional wiring harness. Instead of bringing power to the switch, the inputs need to be grounded. It takes less than 1 milliamp to turn on an input. This means that there is practically no current flowing through the switch, so the contacts will never wear. Additionally, you can use a very light gauge of wire to connect the switch to the MASTERCELL. All of our input wires are 22 AWG as compared to the 12 or 10 AWG wires that came on the OEM harness. This dramatically reduces the bulk of wire under the dash.
