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 Chevrolet Equinox and GMC Terrain (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.

Part 56429 is a custom wiring harness for SUVs and vans. It connects your vehicle's electrical system to a trailer via a 4-flat connector mounted near the hitch. The harness provides signal circuits (7.5 amps per side) and tail/running circuits (7.5 amps total) to control trailer lights.
Part 56429 is designed for SUVs and vans. The wiring connector is located behind the center of the rear bumper (location S6). Check your vehicle's owner's manual to confirm your vehicle has a rear bumper-mounted connector location. If your vehicle does not have a connector in this location, this product may not be compatible.
You will need a flat blade screwdriver and a cutting tool. You will also need a test light, 4-flat tester, or a functioning trailer to verify the harness is working after installation.
Yes. Before beginning installation, locate your vehicle battery using your owner's manual and disconnect the negative battery terminal. Fasten this wire down and away from the battery during installation. Reconnect it after all other installation steps are complete.
1. Locate the vehicle wiring connector along the rear bumper (it will look similar to the custom connector end). 2. Separate the vehicle connector from the weather seal connector carefully, taking care not to damage the locking tabs. 3. Insert the custom wiring connector end fully into the vehicle connector, ensuring the locking tabs are in place. 4. Zip tie the harness into place and mount the 4-flat connector near the hitch.
After connecting the harness, reinstall all items you removed during installation. If you disconnected the negative battery terminal at the start, reconnect it now. Install the provided 4-flat dust cover to help prevent corrosion. Then verify the harness is functioning by connecting the battery and testing with a test light, 4-flat tester, or a functioning trailer.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific lamp load rating.
Signal circuits are rated at 7.5 amps per side. Tail and running circuits are rated at 7.5 amps total.
After reconnecting the battery, verify the harness is functioning by using a test light, 4-flat tester, or by connecting a properly wired trailer. This confirms all signal and running circuits are working correctly before towing.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. This helps prevent electrical failures and corrosion.
The 4-flat dust cover is a protective cover provided with part 56429. Install it on the 4-flat connector after completing the wiring harness installation to help prevent corrosion of the connector.
Mount the 4-flat connector near the hitch after zip tying the harness into place.
You need a flat blade screwdriver, cutting tool, and a test light or 4-flat tester to verify installation. A functioning trailer can also be used for testing.
Yes, disconnect the negative battery terminal before starting installation and reconnect it after completing all other steps.
Signal circuits: 7.5 amps per side. Tail/running circuits: 7.5 amps total.
