My 04 F 150 Lariat was an early build in 10/03. When I look at the overhead rail system DVD units both Ford and Myron & Davis they say for use in 04 builds after 12/03. Does this mean my truck can not have a rail DVD that will work? What did they change the wiring in the trucks after December. With the rail system I can't fit a drop down overhead screen unless its on the rail system. I could put a seperate headrest system in but the rail system would be easier. Anyone have in sight on this?

 

I believe it simply has to do with the fact that the late model 04s had the wiring harness in the headliner already.

Im sure you can get a wiring harness and cable and install it yourself. It isn't that hard.
