How to wire a DVD player into the dome light of our chevy venture van?

We just got a DVD player that mounts to the center dome light in our 04' Chevy Venture, the only problem is that we aren't sure which wires go to which wires. The instructions don't tell us and we can't find any diagrams for the wiring in the venture. Do the red, yellow, and black wires on the DVD player go to the purple, gry and black wires in the dome light or what? What color goes to what color?|||You should only have two wires to the dome light, a positive and a negative. You can tell them apart by one gets grounded by the screw that attaches the light to the roof. Or if you cant figure that one out you will need to buy a light tester.|||Gray/Black is the circuit for the dimmed courtesy lights when shutting doors.

Purple is the switched power feed from your interior light switch

Solid black is ground.



Typically, on aftermarket electronics with wire colors you've described, you want red to be on a permanent power supply, for memory reasons. Yellow will be your switched on power, and black will be ground. ( I could have red and yellow reversed in that analogy, been a long time since I did electronic installs. )



From what I see, you shouldn't be wiring this to the dome lights, unless you constantly run around with your dome lights switched on, because thats the only time the purple wire sees any power.
