Wiring for 2005 Chevy Uplander - which wire goes where?

Question:

I believe the black wire going to the tail lights is ground, dark green must be right turn signal, brown must be tail lights break lights? and what is the light green wire...left turn?

We have a T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, part # 118396, for the 2005 Chevy Uplander that would make installation a breeze. If you are hard wiring in a wiring harness, you can use a circuit tester like part # PTW2993, to identify each wire. Be very careful in making sure the wiring harness you have is correct for your vehicle, as using an incorrect one could damage the electrical system and possibly the computer in your vehicle.
