Truck side trailer wiring problem
Hello all, I have a 2004 GMC Sierra 1500 Z71 crew cab.
My truck is used mainly for towing my trailer and not driven much otherwise and my 10 month old Lab puppy chewed the harness a bit for the 7pin trailer wiring plug on my truck.
I re-connected all the wires by matching the colored wires to one another but have one blue wire left over with no match for it. There was two blue wires, do a couple of them get combined up? The only think on my trailer that isnt working is the electric brakes.
Anyone have a photo of theirs or a diagram? thanks, Im hoping to use my trailer tomorrow.
