Trailer Harness Help
Recently my trailer lights on the passenger side stopped working, Checked for broken wires, all is good. Went to the plug itself on the X, Left side has power but not the passenger side.... lights work on the X no problem there.
could there be a fuse that controls trailer plug output?? Driver side and passenger side.... Or is this a case of back tracing all the wires???
Any thoughts and suggestions greatly appreciated... Thanks

On a 7-pin trailer connector pin #3 provides power for all the running lights - left & right.
Pin #5 is power for the left turn signal and brake light.
Pin #6 is power for the right turn signal and brake light.
Are you having a problem with the running lights or the turn signal/brake?
In 2002, fuse 2.6 in the CJB provides power for both trailer turn signals, there are separate relays for the R & L turn signals.
The Right turn signal relay, K352 is in Aux Relay box 4.
