Towing your vehicle behind your RV is a great way to experience more of the adventure on your cross-country excursions. Whether you're towing a compact car or a full-size truck, CURT has the perfect solution to help you Bring It! CURT towed-vehicle RV harnesses are a vehicle-specific, plug-and-play solution to wiring your vehicle for dinghy towing. They use original-equipment-compatible connectors to plug into your vehicle's wiring system without any cutting, splicing or soldering required. They provide a standard 4-way flat connector to plug into the RV socket and synchronize the vehicle's tail lights, turn signals and brake lights with the RV's. Because each towed-vehicle RV harness has a vehicle-specific design, installation is fast and easy. This particular RV dinghy towing wiring harness is designed for specific years of the Chevy Tahoe and Chevy Suburban (see application info to verify fitment). CURT RV harnesses are also built to provide long-lasting operation. They feature integrated block diodes that protect the vehicle's circuits from the RV signals. They isolate the sensitive vehicle electronics, keeping them from overheating and short circuiting. Every CURT towed-vehicle RV harness comes ready to install with all necessary hardware included. They also come with a 4-way flat extension to provide plenty of length to plug into the RV socket, as well as a connector mounting bracket to mount the connector on the vehicle.

The CURT Custom Towed-Vehicle RV Wiring Harness, Select Chevrolet Tahoe, Suburban Trailer Connector Kit (Part #BKDK58966) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 58966 is a custom RV harness wiring kit designed for SUVs and Vans. It provides a 4-flat connector interface to allow your tow vehicle's taillights to function in sync with trailer lights when towing.
The CURT 58966 is designed for SUVs and Vans. The manual does not specify exclusions by model year, body style, cab configuration, or drivetrain. Consult the product fitment database or contact CURT directly to confirm compatibility with your specific vehicle.
You will need: a drill, a 3/32" drill bit, a panel trim removal tool, and a cutting tool. The manual lists these as required for the installation.
The manual shows an 'Included Parts' section on page 1 but does not list the specific contents. Based on the installation steps, the kit includes a custom RV harness with connectors (green and yellow wire connectors), a 4-flat connector, cable ties, a ground screw, a ring terminal, and a 4-flat dust cover. Contact CURT or check the product packaging for a complete parts list.
Yes. Step 1 requires you to locate the vehicle battery in your owner's manual, disconnect the negative battery terminal, and fasten this wire down and away from the battery. The negative terminal must be reconnected after installation is complete.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This is especially important when drilling the 3/32" pilot hole for the ground wire in Step 4.
The harness is routed in stages: (1) Begin at the rear corner under the vehicle on the driver side with the yellow wire connector installed in the factory harness (Step 2). (2) Route along the rear bumper to the passenger side (Step 2). (3) Route the 4-flat along the fuel fill tube and above the frame rail to the rear of the fuel tank (Step 5). (4) Route above and along the frame rail to just behind the driver-side front wheel (Step 6). (5) Route to the rear of the driver-side wheel well (Step 7). (6) Feed the 4-flat up into the engine compartment below the brake master cylinder and left of the main fuse block (Step 8). (7) Route along the secondary battery box up to the radiator support (Step 9).
In Step 3, route the custom RV harness to the rear corner of the vehicle on the passenger side. Separate the connectors carefully without damaging the locking tabs. Install the connector with the green wire, adjust the harness as needed, and tighten the cable ties so the harness is firmly in place.
In Step 2, begin at the rear corner under the vehicle on the driver side. Separate the connectors carefully without damaging the locking tabs. Install the custom RV harness with the yellow wire in-between the factory harness. Route the harness along the rear bumper to the passenger side and use the provided cable ties to loosely secure the wiring as needed.
Drilling may be required. In Step 4, you must locate a grounding point near the rear corner box. If an existing screw or bolt is not available in the vehicle frame, you will need to drill a 3/32" pilot hole. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it before securing the white ground wire.
Use a 3/32" drill bit to create the pilot hole for the ground wire, if an existing fastener is not available. The hole is drilled in the vehicle frame near the rear corner box in Step 4.
The harness includes: a yellow wire connector (installed in the factory harness at the driver-side rear corner in Step 2), a green wire connector (installed at the passenger-side rear corner in Step 3), and a white ground wire with a ring terminal (secured to the frame in Step 4). The 4-flat connector is routed from the rear to the engine compartment.
The 4-flat connector is routed in the following sequence: (1) Along the fuel fill tube and above the frame rail to the rear of the fuel tank (Step 5). (2) Above and along the frame rail to just behind the driver-side front wheel (Step 6). (3) To the rear of the driver-side wheel well (Step 7). (4) Up into the engine compartment below the brake master cylinder and left of the main fuse block (Step 8). (5) Along the secondary battery box up to the radiator support (Step 9). Use cable ties to loosely secure the wire along the frame rail as needed.
In Step 4, locate a grounding point near the rear corner box, such as an existing screw or bolt in the vehicle frame. If one is not available, drill a 3/32" pilot hole. Clean the area of rust, dirt, and paint using an abrasive pad or paper. Secure the white ground wire with the ring terminal to the existing fastener or use the provided ground screw.
After installation, verify that the harness is functioning by attaching the 4-flat connector to any vehicle with functioning trailer lights. The taillights on the tow vehicle should function along with the taillights on the towing vehicle. This test confirms proper wiring and connection.
After installation: (1) Tighten any zip ties and add as needed to secure excess wire so it is not drooping or dangling, but not so tight that it causes strain and breakage (Step 10). (2) Reinstall all items removed during installation. (3) Reconnect the negative battery terminal if it was disconnected. (4) Install the provided 4-flat dust cover to help prevent corrosion.
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; perform checks as part of routine vehicle maintenance or before towing.
Yes. The provided 4-flat dust cover should be installed to help prevent corrosion. This is done as the final step of installation (Step 10).
The CURT 58966 is designed for SUVs and Vans. Confirm fitment with the product database or contact CURT, as the manual does not list specific model years or exclusions.
You need a drill, 3/32" drill bit, panel trim removal tool, and cutting tool. Professional installation is not required; the difficulty level is listed as Easy.
Yes, disconnect the negative battery terminal before starting installation and reconnect it after completion. Fasten the wire down and away from the battery during installation.
Drilling may be required. If an existing fastener is not available for the ground wire, drill a 3/32" pilot hole in the vehicle frame. Always check for hidden items before drilling.
The harness includes yellow and green wire connectors for the rear lights, a white ground wire with ring terminal, and a 4-flat connector routed to the engine compartment.
Attach the 4-flat connector to a vehicle with functioning trailer lights. The tow vehicle taillights should function along with the trailer lights, confirming proper installation.
