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 F150. 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 58970 Custom Towed-Vehicle RV Wiring Harness for Dinghy Towing, Fits Select Ford F-150 (Part #BKDK58970) is designed to fit the 2015-2018 Ford F-150.
The CURT 58970 Custom Towed-Vehicle RV Wiring Harness for Dinghy Towing, Fits Select Ford F-150 (Part #BKDK58970) fits 2015-2018 Ford F-150 models. The 2018 model year is the last year covered by this part number. For newer models, check for an updated version.
The CURT 58970 Custom Towed-Vehicle RV Wiring Harness for Dinghy Towing, Fits Select Ford F-150 (Part #BKDK58970) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 58970 is an RV harness designed for trucks. It integrates with your vehicle's factory wiring to enable towing functionality. The harness connects at the rear of the vehicle and routes a 4-flat connector wire to the front engine compartment for proper electrical integration.
The manual confirms the CURT 58970 is designed for trucks and references wiring locations T1–T5 (behind driver and passenger taillights, rear bumper areas, and center of rear bumper fascia). However, the manual does not list specific vehicle makes, models, or model years. Contact CURT Group or consult a fitment database to confirm compatibility with your truck.
You will need: a cutting tool, a panel trim removal tool, and fish wire. Fish wire can be made from a cut-up wire hanger, stiff wire, rope, or string, depending on what is needed for routing the harness through the fender well.
Yes. Step 1 requires you to locate the vehicle battery (consult your vehicle's owner's manual for location), disconnect the negative battery terminal, and fasten this wire down and away from the battery. Reconnect the negative terminal only after all other installation steps are complete.
The factory harness is located on the rear driver side between the frame rail and the spare tire. It will be similar in appearance to the new RV harness. You will separate it from its mating housing by releasing the locking tabs in Step 2.
Route the 4-flat wire above the frame rail on the driver side toward the front of the vehicle, securing it loosely with cable ties as needed (Step 4). Once the wire reaches just behind the front tire, use fish wire to route it through the inner and outer fender to the fender and wheel well area (Step 5). Attach the 4-flat to the fish wire and pull it up to the top of the engine compartment, routing it around the body mount and above the sub frame, then up between the inner and outer fender (Step 7). Finally, route the wire along the driver-side inner fender and under the air box mount, mounting the 4-flat just behind the driver-side headlight (Step 8).
Fish wire is a tool used to push or pull an electrical wire through a blind hole (a hole you cannot see through). For the CURT 58970, you insert the fish wire through the blind hole between the inner and outer fender, locate it on the other side, use tape to secure the harness to the fish wire, and pull it back up. If the fish wire or harness gets hung up, push back down, wiggle it around, or twist the wire to loosen it. Fish wire can be made from a cut-up wire hanger, stiff wire, rope, or string.
Secure excess wire so it is not drooping or dangling, but not so tight that it causes unnecessary strain, which could lead to breakage over time. Use cable ties to loosely secure the wire along the frame rail as needed during routing (Step 4), and 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 (Step 9).
After routing and securing the 4-flat wire, 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. Test the harness for proper function using a test light or by connecting a properly wired trailer.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Exceeding either limit may result in electrical failure or damage to your vehicle's lighting system.
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 exact interval; perform inspections regularly, especially before towing.
Check all wires and connections for visible damage (cuts, abrasions, or exposed conductors) and loose connections. Ensure that cable ties and fasteners are secure and that wires are not drooping, dangling, or under strain.
The manual rates the installation difficulty as 'Easy.' However, the installation involves routing a 4-flat wire from the rear of the vehicle to the front engine compartment using fish wire through the fender well, which requires careful attention to the routing steps and proper wire management.
