I have a 03 excursion 7.3lwith no factory DVD player I picked up a DVD player and screen from a Local junkyard that came from an 05 excursion. Does anyone know if my 03 is already wired for the DVD player, being that it was a factory option? If not does anybody know where I can get a wiring diagram for an 05 that would identify the connections to the DVD player that I have? Any help would be greatly appreceiated

I have been running my own biodiesel in the 03 for about 15,000 miles with great sucess, ifanyone hasany questions about running biodiesel feel free to ask.
