does anyone have a wiring diagram for a f250 03 7.3l crewcab king ranch dually. i specifically need the diag that shows the tralier wiring that controls the idiot light in the instrument cluster when a trailer is connected and disconnected.

 

nevermind i figured out what the guy's problem was it was his blue trailer brake wire shorting to the frame due to the insulation being rubbed through. lol he told me he's taken it to ford 4 times to try and get it fixed because they installed it and they just ended up cutting the wire where it was spliced into the factory harness cause they couldnt figure it out.

this thread can be deleted now thanks.
