Trailer 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

Connecting color-to-color is like building an airplane
out of bamboo in hopes another will land... cargo-cult
electrics. 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:

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.

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:

True enough, but the color codes I listed below came directly off the
instructions included with the factory pigtail for our Grand Cherokee.
The colors do match what the OP listed for his XJ, so I assume they
are correct.
