2005 Ford F150 retaining dvd

if you contact Ford they should be able to get a wiring schematic for you.  I had a guy who owned an Expedition with factory TV and totaled it, and the insurance company replaced it with one without the TV.  The guy went to the junkyard and removed the tv, and brought me a print out of the wiring diagram.  I soldered on the power, ground, audio and video leads and was able to get it to work.  I think that it was an 04, but I think the 05 is the same.  One of my guys tried to replace the factory in dash on an 06 Navigator and keep the factory TV, but with no luck.  Aparently there is a digital turn on between the factory deck and TV on that model, at least that is what we were told.
