Installing 4-Pole Trailer Connector on 2000 Chevy Slilverado

Question:

Ive wired a set of TL8RK trailer lights on my small trailer. Now trying to come off the back of the truck I have four different connectors all located on a center plate under by the spare. I have 2- Lt blue wires, 2-green wires, a brown and white striped wire, brown wire, dk blue, and black. Which wires do I connect the four trailer wires to.

Are you speaking of the wiring harness located above the spare tire? The harness is wrapped in wire loom, and should contain a yellow wire (left turn/brake), dark green wire (right turn/brake), brown wire (running lights) and a white ground wire. Peel back a bit more of the loom, and you should find a light blue and a light green wire. The light blue provides a signal for a third brake light if you installed a camper shell and the light green wire is for the reverse lights.

A typical 4 pole connector like part # 18002 uses the yellow wire for the left turn/brake, green wire for the right turn/brake, brown wire for the running lights and the white wire for ground. You might also be interested in a bracket, part # 18144.
