most dont come with a wiring harness for trailer but if you look under the driver side of the truck under the bumper you will see a bundle of wires and there should be a paper located on the wires to match up a wiring harness. The ground is a large white wire and hook up other wires color to color. Most wiring harnesses are 4 wire but you should have enough for a 6 wire on the truck but only use 4. I just wired mine up last week!

If all you want to do is change a bulb, you pull the license plate off to gain access to the wiring harness. After you twist the harness counter clockwise to loosen the harness, let it drop down and access it to change the bulb from underneath the car.
