If you are looking for the custom adapter for the Curt Reflex Trailer Brake Controller # C51130, you will need the Universal Wiring Adapter for Curt Trailer Brake Controllers # C51515.

Unfortunately, no factory plug is present under the dash on your truck, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash. It is a two foot long wire. These are twelve gauge wires with a protective coating to prevent damage, called a wire loom. There is a tag on it that shows you the colors and where they do attach. The black is the battery power, white is the ground, red is the brake signal, and blue is the electric brake feed to the trailer.

If you also need a 7-way connector at the back of your truck, use part # PK11898 as long as there is a round connector to plug it into. The connector will likely have a cap on it. If you don't have that connector and instead have a bundle of wires above the spare tire use part # 30955.
