I have 4 run switches up in the same location. I use a small gauge wire to run to trigger relays. Works great for lockup switches, lights, nitrous, water/ meth, ect. Even kill switches.

I run a larger 12+v and bridge to all the switches. My set also requires a ground to get the LEDs to light up when on.

Hmmm... I cheated and used light duty cord... Like for small appliances its got a heavy jacket on it but it made the runs in the head liner easy and neat... I grab my camera and shoot a few pics of this cable... I used the same stuff for the overhead beacon light too..

Just a crazy idea to toss out on this...
