I have a 94 k-1500 sub. Does anyone know the wiring diagram for the trailer wiring harness? It already had the the 4-way harness for a trailer when I bought it. There's 2 other wires not being used and I wanted to know what would they be used for? The colors are red and blue and there about 12 gauge. Also I'm trying to figure out if the the 4-way harness I have is bad. The brake lights ,driving lights and the hazards work, but the turn signals will not flash when needed. can someone help me please?
