I just picked up an '05 Silverado Crew Cab. I have a roof mount DVD player that would work great for the rear passengers. I popped out the dome light and see the wiring to it is: red (or orange), black, and gray. For the DVD player, I need to wire in +12V, ACC, Ground, and possibly Door (the roof mount DVD player has dome lights built in). I figure I can get the +12V, Ground, and Door from the existing dome light wiring. I think I'll then have to fish a wire through the headliner to get to ACC. Does this sound right? Any thoughts or advice would be appreciated. Thanks.
