    On my new truck I have a switch right in the middle of the truck, just about on the roof. In the book it says it's an optional emergency light switch that can be wired up by a GM factory authorized mechanic. I was wondering if anyone knows where those wires come down to. I hope it's as simple as Ford with their switch board, but I doubt it.

    I think they put the wires in the headliner above the drive towards the back for you to connect a light.

    Some have said on the 2011's the headliner doesn't need to come down.

    I can tell you in 2010s, the wires (hot and ground blunt cut) was bundle up in the roof console where the switch is, pull the console down (remove ligth cover, remove 2 screws from there, then just pull down), run a fish line in from the third brake light, and you can run the wire out there for a roof light, never having to touch the headliner.
  6. Just did mine the other night it should be right above the interior lights and switch itself. Real easy to get at just drop lense to interior light,remove screws and pop plastic down. You will find it all wrapped up right there. Good luck
  7. Oh yeah green is power and black is the ground. Also it is rated at 30 amps
