2003 Expedition Overhead DVD Not Working w/New Radio

I have a 2003 Ford Expedition Eddie Bauer (with the Overhead DVD Player)

Recently my stock head unit when bad and I had it replaced at a shop. Now my DVD player does not work at all. Is there any way/suggestions on how to re wire it so it will work? I figure I can just wire it into the 12volt system, switch it, and use a LOC on the sound wires and have it goto a 3.5mm (my HU has an input). My question is, before I take it down, can any one tell me if the wires are marked and or what colors are what? Thanks.

any suggestions on other ways to make it work would be apprecated :)

There's a wire in the radio harness that has to see +12V to turn on the rear DVD.  I think it's light GREEN/ black.

Audio should be :

Left pos - white

left neg - light green

right pos - red

right neg - black

Those are low level, you shouldn't need an LOC.  All these wires are in a separate plug in the radio harness bundle. 

Metra makes a plug to integrate the factory DVD with an aftermarket stereo, model number is 70-5520AV.  With that you wouldn't have to do any splicing or cutting of the factory harness.  Their website says it works to retain factory DVD players on 03-06 Fords.  Sounds like just what you're looking for.  That would take all the guess work out and save you some time and headache.

If you can't get your hands on one of those, then the way you described should work to acheive the same results. 

Thanks. I'll read up on that

The GREEN/ black will power up the DVD, but the headphones won't work.  You need to pull the DVD down and access the gray plug behind it . Connect the following

Pin 7 red to pin 5 white

Pin 17 white to pin 15 green

Pin 8 orange to pin 6 red

Pin 18 pink to pin 16 black.

Use a short piece of wire and jump them together. This will make the headphones work.  To get a video signal, look at the plug on the side of the DVD console. There are two wires twisted together, yellow and black. Yellow is the positive signal and black the neg.

when you say pull down the dvd player, what kind of screw driver do I need? I cant see up there to figure it out.
