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 Ford F-150 with backup sensors (not compatible with LED taillights). 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.

Yes, the CURT Custom Towed-Vehicle RV Wiring Harness for Select Ford F-150 with Backup Sensors Trailer Connector Kit (Part #BKDK58989) is designed to fit the 2021-2023 Ford F-150.
The CURT Custom Towed-Vehicle RV Wiring Harness for Select Ford F-150 with Backup Sensors Trailer Connector Kit (Part #BKDK58989) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Part 58989 is a Curt Manufacturing RV harness (trailer wiring harness) that allows you to connect a trailer to your truck. It routes power from your truck's taillights to a 4-flat connector at the front of the vehicle, enabling your trailer lights to function when towing.
The manual does not specify which vehicle makes, models, or years are compatible with part 58989. Contact Curt Manufacturing or your retailer with your vehicle's year, make, model, and bed length to confirm fitment before purchasing.
The manual does not address compatibility with factory-integrated towing packages or trailer brake systems. Contact the manufacturer to confirm whether the 58989 can be used alongside or instead of factory towing equipment on your specific vehicle.
You will need: a ratchet, an 8mm socket, a socket extension, a drill with a 3/32" drill bit, a cutting tool, and fish wire (or a stiff wire, rope, or string to route wires through blind holes). Proper tools will improve installation quality and reduce installation time.
The manual confirms that a ground screw, a ring terminal for the white ground wire, a 4-flat connector, and a 4-flat dust cover are provided. The harness includes yellow, green, and white wires for taillight and ground connections.
Yes. Step 1 requires you to locate the vehicle battery and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation to prevent accidental reconnection.
Yes. Step 2 requires you to open the tailgate to access the two 8mm bolts that secure each taillight in place. You will repeat this on both the driver and passenger sides.
Open the tailgate. Use an 8mm socket and ratchet to remove two bolts securing each taillight in place. Then pull the taillight straight back. Carefully remove the connectors, taking care not to damage the locking tabs on the back. Repeat on the other side of the vehicle.
Fish wire is a tool used to push or pull an electrical wire through a blind hole. Insert the fish wire through the hole and locate it on the other side. Use tape to secure the harness to the fish wire and pull back up. If the wire gets hung up, push back down, wiggle it, or twist it to loosen it. Fish wire can be a cut-up wire hanger, stiff wire, rope, or string.
Beginning on the driver side, drop a fish wire down inside the box where the taillight was removed. From under the vehicle, attach the yellow wire to the fish wire and pull it up into the taillight opening. Attach the RV harness to the taillight, then re-attach the factory harness to both the taillight and the RV harness. Route the green wire over to the passenger side, zip-tying it as needed to the rear bumper, then repeat the process with the green wire on the passenger side.
Locate a grounding point such as an existing screw or bolt in the vehicle frame, or drill a 3/32" pilot hole if needed. The area must be free from rust, dirt, and paint—use an abrasive pad or paper to clean it. Secure the white ground wire with the ring terminal on the existing fastener or with the provided ground screw.
Drilling is required only if you do not have an existing screw or bolt in the vehicle frame to use as a grounding point for the white ground wire. If drilling is necessary, use a 3/32" drill bit to create a pilot hole. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Use a 3/32" drill bit to create a pilot hole for the ground screw if an existing fastener is not available.
Route the 4-flat harness above the frame and below the bed of the truck along the driver-side frame rail to the front. Once the harness is just behind the driver-side front wheel, route it to the rear of the driver-side wheel well, then over to the driver-side rear inner wheel well. From the engine compartment on the driver side next to the hood hinge, run a fish wire down between the inner and outer fender. Pull the wheel well panel back, locate the fish wire end, attach the 4-flat to it, and pull it to the top of the engine compartment. Finally, route the 4-flat along the driver-side inner fender and under the air intake to the front of the truck.
Secure any excess wire so that it is not drooping or dangling, but not so tight that it causes unnecessary strain to the wire, which could lead to breakage over time. After removing slack from the 4-flat wire, tighten any zip ties and add as needed. Use a zip tie to fasten any excess wire to a solid spot along the driver-side inner fender.
Reinstall all items removed during installation. If the negative battery terminal was disconnected at the beginning, reconnect it. Install the provided 4-flat dust cover to help prevent corrosion.
The manual states: Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. However, the specific amperage or wattage rating for the 58989 is not provided in the manual. Contact Curt Manufacturing for the exact product rating.
Do not lay tools across the positive terminal (typically noted with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks. When you disconnect the negative battery terminal in Step 1, fasten this wire down and away from the battery to prevent accidental reconnection.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and/or personal injury. This is especially important when drilling the 3/32" pilot hole for the ground wire.
Once the RV harness is installed, verify that it is functioning by attaching the 4-flat to any vehicle with functioning trailer lights. The taillights on the tow vehicle should function along with the taillights on the towing vehicle. You can also use a test light to check for proper function.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Install the provided 4-flat dust cover to help prevent corrosion.
The manual does not list specific vehicle compatibility. Contact Curt Manufacturing or your retailer with your vehicle's year, make, model, and bed length to confirm fitment.
You need a ratchet, 8mm socket, socket extension, drill with 3/32" bit, cutting tool, and fish wire (or stiff wire/rope). All tools are listed in the manual's Tools Required section.
Yes. Disconnect the negative battery terminal in Step 1 and fasten it away from the battery. Reconnect it after all wiring is complete.
Drilling is required only if you do not have an existing screw or bolt in the vehicle frame for grounding the white wire. If drilling is needed, use a 3/32" drill bit and check for hidden items first.
The manual does not provide a torque specification for the 8mm bolts securing the taillights. Consult your vehicle's service manual or contact the manufacturer for the correct torque value.
