I'm wiring my truck (92 Dakota) for pulling a trailer. I won't be using trailer brakes because it's just a small utility trailer.
I've got a 6 way plug that I'm using. I've found a wiring diagram online, but I'm confused about a couple things. The truck previously had a plug wired in, but was removed at some point. All the spliced in wires are still there though.
I've got three wires on the truck.
Wire 1 is hot when: left turn, headlight, brake
Wire 2 is hot when: right turn, brake
Wire 3 is never hot, but shows resistance. I'm assuming this is ground.
I'm confused because the wiring diagram I've got shows a separate wire for tail lights.
I'll keep googling, but any help is much appreciated. Thank you!
