in case it moves before you get a chance to see it. DirToyBoy found this:

I believe there is a Bat connection that carries the load of the compressor so the Ign. wire only powers the relays and solenoids.
You can connect that to almost any circut that is controlled by the IGN. switch. Or tap into the IGN wire comming off the key switch so long as there is an in line fuse and I remember there being one.
The illumination only lights up the switches so you can see them in the dark. So find a wire that goes to your instrument panel you can tap into for this. Maybe you have a light in the ash tray?
BTW, that ARB harness has more wires than I have in the Mammoth.
