Back to the wiring, I will only use covered connectors as shown. These connectors take quite a bit of abuse with out shorting your wires. You will only need one female and one male for this install, as the reverse lights already have connectors attached to them. For this reason these connector are not listed on the parts needed. The set of connectors will be placed on the license plate light in case it ever has to be replaced. On the license light I bought there was already a connector for a GM product. Clip this connector off and replace it with the new male connector.

On the left side harness you need to run a short piece of black wire, with one end being soldered and heat shrunk to the black (running lights) of the 3 pin connector and the other having a new female connector to mate to the license plate light connector. Next, on both harnesses solder and heat shrink the 2 pin connectors to their respective wires on the 3 pin connectors, making sure to leave enough length for the wires to span the distance between the rear light and the running light. I use mini zip ties for stress relief. This should be done on each side of a solder joint, to prevent the joint from breaking. The harnesses are done for now. We will get back to them after disassembling the factory lights.

Remove the lenses from your existing tail lights, 4 phillips screws per light. Remove the 3 bolts per light that hold them to the tub. Pull the wiring through the hole in the tub so that you can reach and disconnect the original harness. The right side is different from the left side so keep them separate and know which one goes where. Clip the wires of the existing tail light close to the light. You will also have to strip back the protecting cover on this wire harness. The purple wire will need to be soldered and shrunk to the positive wire for your reverse lights. The wire length will vary depending on where you located your reverse lights. The black wire on this harness will be soldered and shrunk to the black wire of the LED harness. Use hook joints for these connections. Form each end in the form of a “J” then pull them together such that they interconnect and pinch them together. Then solder and you will have a nice/strong connection. Next I added some length to the ground wire on the LED harness, this is the white wire on this harness. I added about 6” of black 14 gauge wire and then used a ¼” eye connector, I crimped this wire and the ground from the reverse lights together to give me one ground connection I had to make. Again the length of your ground wire will vary depending on where your reverse lights are mounted. Now, the only thing left is soldering and shrinking the turn signal wires. The original wire harness that was cut from the factory lights will have a brown wire for the right hand light and a green wire for the left hand light. You need to solder and shrink these wires to their respective red wires on the LED harnesses.
