i have a 93 Ranger, that i need to put a trailor wiring harness on. The harness was on it when i got it but had bad connectors and a bad ground, because the connectors were not weather tight. The harness is still good, but has no labels as to what color wire goes where on the truck. I didnt label them when i took it off because i wasnt planning on using the truck for pulling a trailor. Now i need to so i need to reinstall the plug. It has a flat 4 prong plug with 5 wires going to the truck. Brown, White, Yellow, Green, and Red. I know the white is the ground but need help after that. The truck has amber turn signals so it has to be wired for those plus the stop lights.
