Car Forum / Jeep / June 2005Trailer Wiring Problem
Hey All, I have a 90 XJ with a stock Class 4 Hitch. The stock plug has 7 wires blue, yellow, green, brown and red 14? gauge and black and white 10? gauge.Trailer has 5 wires brown & green for right tail/brake and brown &yellow for the left tail/brake and a white ground. when hooked up color to color exept for white (white trailer wire grounded to XJ), black, red and blue. The left turn signal doesn't flash, right turn flashes both sides, brake lights up both correctly. I can't figure it out, any help will be appreciated. Thanks > Hey All, I have a 90 XJ with a stock Class 4 Hitch.

Don't do this again, for anything except house wiring... you're lucky you didn't see smoke. Here's a link to a diagram for your connector: http://dodgeram.org/tech/mods/electric/trailer_wire.htm Reese makes adapters that will plug your two units together... they're not very cheap, especially for the honking 7-conductor unit you've got. What I did for mine like that was to buy the plug and create my own adapter... if you just need to do this once, you can create jumpers out of crimp-on connectors, or, just cram stripped wires into the holes and tape... yes, I know, but it works, and it will get you home. __ Steve . >Hey All, I have a 90 XJ with a stock Class 4 Hitch.

Thanks 1 = White = Ground 2 = Blue = Trailer Brakes 3 = Green = Tail Lamps 4 = Black = 12-volts DC 5 = Red = Left Turn & Brake 6 = Brown = Right Turn & Brake 7 = Yellow = Backup Lamps Unfortunately every vehicle manufacturer uses their own color coding system for trailer wires. This has been a pet peeve of mine for years, but anyway, this should fix you up: The taillight wires on the trailer harness are brown, they should both go to the green wire on the vehicle. The left turn wire on the trailer is yellow and should go to the red wire on the vehicle. The right turn wire on the trailer is green and should go to the brown wire on the vehicle. Here is a pretty decent site for all the color codes: http://www.etrailer.com/faq/wiring.asp Chris > >Hey All, I have a 90 XJ with a stock Class 4 Hitch.

The colors do match what the OP listed for his XJ, so I assume they are correct. Dick >Unfortunately every vehicle manufacturer uses their own color coding system >for trailer wires.
