The Curt 56375 is a custom wiring connector that provides a 4-flat trailer connector interface for your vehicle. It connects to the vehicle's existing wiring connector located along the rear bumper and allows you to connect a trailer with proper lighting control. The connector includes relays that must be installed in the vehicle's fuse panel (positions K2 and K3) to manage signal and tail/running light circuits.
Yes, the Curt 56375 is designed for Chevrolet Equinox SUVs, Mini & Full-Sized Vans (S). The connector mounts behind the center of the rear bumper. If you have a different vehicle model or year, contact the manufacturer or consult a fitment database to confirm compatibility.
You need a flat blade screwdriver and a cutting tool. The screwdriver is used to remove the fuse panel cover, and the cutting tool may be needed during installation. The manual does not specify additional tools or whether professional installation is recommended.
The kit includes the custom wiring connector, two relays (for installation in fuse panel positions K2 and K3), a 4-flat dust cover, and cable ties for securing loose wires.
The vehicle wiring connector is located along the rear bumper, behind the center. It will be similar in appearance to the custom wiring connector included in the kit. You will separate this connector from the weather seal connector as the first step of installation.
1. Locate the vehicle wiring connector along the rear bumper. 2. Carefully separate the vehicle connector from the weather seal connector, taking care not to damage the locking tabs. 3. Insert the custom wiring connector end into the vehicle connector. 4. Ensure the connectors are fully inserted with locking tabs in place. The connectors must be fully seated for proper function.
The two relays must be installed in the vehicle's fuse panel in positions K2 and K3. To access the fuse panel: 1. Open the vehicle tailgate. 2. On the driver side, locate the fuse access panel cover on the side trim. 3. Remove the fuse panel cover. 4. Install the relays in positions K2 and K3 as shown on the fuse cover. 5. Reinstall the fuse panel cover.
When in use, route the 4-flat out from the vehicle. When not in use, roll it up and store it in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent damage and maintain a neat appearance.
The provided 4-flat dust cover helps prevent corrosion of the connector. Install it after the custom wiring connector is fully connected to the vehicle connector. The manual does not provide specific installation details beyond this instruction.
