Go to www.installdr.com and search through the diagrams in there, the site is easy to use, all you need is acrobat reader installed on your computer to use the site, it has a full explanation on every wire color and what it is

SOURCE: need wire diagram to hook up trailer lights, truck not factory equipped w/harness,

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location
