If your taillight harness has been hacked this info is no good but the standard colors at your truck should be as follows.

Brown-----Tail Light
Yellow-----Left Turn/Brake
Dk Green---Right Turn/Brake
Lt Green---Reverse
Black------Ground

Your new lights more than likely grounded through the mounts but with out pics of what lights you have IDK. This will leave you with one wire being tail, one being turn/brake, and one being reverse.

If you have different colors you'll have to start some investigation with a test light.
