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 Buick Encore (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 harness is rated for Signal Circuits at 3.0 amps per side and Tail/Running Circuits at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
You will need a panel trim removal tool. A drill with a 3/32" bit may be needed if you do not have a suitable existing screw with nut for the ground wire attachment point.
Yes. Step 1 requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before beginning installation.
The yellow wire end connects to the driver side taillight wiring harness connectors. Insert it between the separated connectors and ensure the connectors are fully inserted with locking tabs in place.
The green wire end connects to the passenger side taillight wiring harness connectors. Route it behind the removed scuff panel and repeat the same connection procedure as the driver side (Steps 4-6).
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole. Clean the area of rust, dirt and paint, then secure the white ground wire using the ring terminal and provided screw.
Drilling is not always required. You may use an existing screw with nut in the vehicle frame as a grounding point. Drilling is only necessary if no suitable existing fastener is available. If drilling is needed, a 3/32" pilot hole is required for the provided ground screw.
Drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.

When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or by connecting a properly wired trailer. All installation steps must be followed to ensure the wiring harness functions properly.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire.
Exceeding the product rating (Signal Circuits 3.0 amps per side, Tail/Running Circuits 6.0 amps total) or your tow vehicle's lamp load rating, whichever is lower, can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or the 10-amp maximum fuse protection.
Remove the two 10mm bolts and cargo fasteners on each side of the rear scuff panel. Pull out on the bottom and then up to remove it. Take care not to damage the alignment tabs on the back. The panel is removed to access the wiring harness routing behind it.
Yes. Step 2 requires you to open the vehicle tailgate and remove all trunk floor coverings and storage trays to access the rear scuff panel and wiring harness routing areas.
Remove the plastic access cover from the interior trim panel to locate the vehicle taillight wiring harness. Carefully move the lower interior trim panel to be able to route the custom wiring harness.
Locate the vehicle taillight wiring harness connectors. Separate them from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow for driver side, green for passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
