Default 2002 rear wiring diagram and colors

Hi All
I am looking for a wiring diagram for the rear taillight harness.
My new to me tow truck is a 2002 GMC 3500 and someone has done a butcher job on the wiring for the wrecker deck.
I want to clean it up and would like to get a diagram or at least a description of what each color wire is supposed to do.Right now when use one of the turn signals it flashes both sides,but use the other side and it works fine.I would like to have all OEM wires doing what they are supposed to do,plus be able to hook up a brake controller.
Thanks for the help
Thomas

Maybe one of these is the one you're looking for?

Thanks that helps some.
I was hoping to find a breakdown on the different colors in the rear harness and what they do.
This was a dually P/U but the rear junction block has been removed and the harness has been spliced into.An Aftermarket junction box had been used on the wrecker deck,which has been damaged and there are way to many wires clumped together that don't really need to be there.
