I have a 2007 GMC Sierra Crew Cab-Diesel
Problem #1
I installed an over head DVD unit. I tried to use the existing wiring but I think that I blew a fuse, but I can't find which one ... Please help

Problem # 2
The DVD unit has dome lights, But I can't seen to get them to work when the door is open. Ithink that it may have something to do with negative switching (that's what the DVD unit is )

Please help...again!
