Truck listed above is a 1500 Laramie. Someone previous messed the harness...well they all worked until I change burned out bulbs and now I don't know. There is a spliced wire into one that went directly into bulb socket and there are repeat colour wires on each side so I'm at a loss when looking at wiring diagram....

Hi,

I suspect someone wired in trailer lights or something similar. As far as the wiring, I attached the wiring schematics below for the exterior lights. I had to cut the pic in half to make it readable, but I did overlap them so you can follow from one to the next. If you look in pic 2, I circled the rear lighting section.

Here is a link you may find helpful when working on this:

I hope this helps. Let me know if you have other questions or need anything.

Take care,

Joe
