If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Chevy G10, G20 and G30 and GMC G1500, G2500 and G3500 (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

The kit includes a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, and a provided screw for grounding. A panel trim removal tool is required but the manual does not specify whether it is included in the kit.
You will need a panel trim removal tool to access the taillight wiring. A drill may be required if a suitable existing grounding point is not available. A test light, 4-flat tester, or functioning trailer is needed to verify proper function after installation.
Yes. Step 1 requires you to locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation.
1. Locate the vehicle's taillight wiring harness on each side behind the taillights. 2. Disconnect the vehicle harness connectors on the driver side. 3. Position the custom wiring end with the yellow wire between the separated vehicle connectors. 4. Firmly press the connector ends together until the locking tabs engage, taking care not to damage the alignment tabs. 5. Repeat on the passenger side using the custom wiring end with the green wire.
Route the custom wiring end with the green wire out from under the trim panel and along the threshold to the passenger side of the vehicle. The yellow wire end connects on the driver side and the green wire end connects on the passenger side.
Not necessarily. First, locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt, and paint. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Drill a 3/32" pilot hole if an existing grounding point is not available. The area should be free of rust, dirt, and paint before securing the white ground wire using the ring terminal and provided screw.
After reattaching the battery, verify the harness is functioning by testing with a test light, 4-flat tester, or a functioning trailer. The manual does not provide specific test procedures or expected results.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. The manual does not specify the product's rating or capacity. Consult the product documentation or Curt Manufacturing for this specification.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval.
Yes. Open the rear doors of the vehicle and temporarily remove the inner trim panels on each side near the rear doors. This exposes the taillight wiring access ports and the threshold trim plate along the floor across the door opening.
