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 Ranger. 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 Ford Ranger Trailer Connector Kit (Part #BKDK58986) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Part 58986 is a custom wiring harness for trailer lights manufactured by Curt. It connects your truck's electrical system to a trailer's light connectors, allowing the trailer lights to function when towing. The harness includes a 4-flat connector for the trailer, a ground wire with ring terminal, and custom wiring with yellow and green connectors that integrate with your vehicle's existing electrical system.
The manual specifies this harness is designed for trucks with wiring locations designated T3 and T5 (behind the driver and passenger side rear bumpers). The manual does not list specific vehicle makes, models, or years. Consult the product listing or contact Curt Manufacturing to confirm fitment for your specific truck.
You will need: a drill, a 3/32" drill bit, a cutting tool, fish wire, a panel trim removal tool, and electrical tape. A test light or a properly wired trailer is also recommended to verify proper function after installation.
The harness includes a custom wiring harness with yellow and green connectors, a white ground wire with ring terminal, a provided ground screw, a 4-flat connector for the trailer, and a 4-flat dust cover. The manual does not specify whether additional fasteners or zip ties are included.
Yes. Step 1 requires you to locate the vehicle battery and disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery while completing the installation. Reconnect it after all installation steps are complete and items have been reinstalled.
The manual rates this installation as 'Easy' based on time and effort involved. However, the difficulty may vary depending on your expertise, your vehicle's condition, and whether you have the proper tools. The installation involves routing wiring through the vehicle frame, drilling a potential ground hole, and making electrical connections, so basic mechanical and electrical knowledge is helpful.
The yellow wire connector is inserted at the driver side rear bumper (location T3), between the separated connectors with the red external lock. The green wire connector is inserted at the passenger side rear bumper (location T5), also between the separated connectors. Both must be fully inserted with locking tabs in place. Loosen the red external lock before inserting and ensure the locking tabs are secure after insertion.
Route the harness as follows: (1) Begin at the driver side rear bumper (T3) on the outside of the frame rail. (2) Route along the rear bumper to the passenger side (T5), loosely zip tied. (3) Route to the passenger side, keeping above the frame and hitch. (4) Route to the rear of the outside of the vehicle frame rail. (5) On the driver side, route the 4-flat along and above the frame rail to just behind the driver-side front wheel, keeping clear of pinch points, moving and hot components. (6) Route along the frame rail up to the lower firewall, then along the firewall near the brake lines to the top of the engine compartment. (7) Mount the 4-flat in the front of the vehicle under the hood on the driver side inner fender.
Drilling may be required for the ground connection. You must locate an existing screw or bolt in the vehicle frame to use as a grounding point. If no suitable existing fastener is available, you will need to drill a 3/32" pilot hole. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it.
Use a 3/32" drill bit to create the pilot hole for the ground connection, if an existing fastener is not available.
Locate a grounding point such as an existing screw or bolt in the vehicle frame. If no existing fastener is suitable, drill a 3/32" pilot hole. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to remove any corrosion. Secure the white ground wire with the ring terminal to the existing fastener or use the provided ground screw. The manual does not specify a torque value for the ground screw.
The yellow wire connects at the driver side rear bumper (T3) and the green wire connects at the passenger side rear bumper (T5). These are the custom harness connectors that integrate with your vehicle's existing trailer light electrical system. The manual does not specify the individual functions of these wires beyond their connection locations.
Keep the wiring clear of pinch points, moving and hot components. Do not route the wiring too tightly, as this can cause breakage over time. Secure excess wire so it is not drooping or dangling, but with enough slack to prevent strain. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
After installation, verify that the harness 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 verify proper function.
After all wiring steps are complete: (1) Secure any excess wire so it is not drooping or dangling, but not so tight that it causes strain. (2) Tighten any zip ties and add as needed. (3) Use a zip tie to fasten any excess wire to a solid spot along the driver-side inner fender. (4) Reinstall all items removed during installation. (5) Reconnect the negative battery terminal if it was disconnected. (6) Install the provided 4-flat dust cover to help prevent corrosion. (7) Test for proper function using a test light or a properly wired trailer.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval or other maintenance procedures.
Yes. Install the provided 4-flat dust cover after completing the installation to help prevent corrosion of the 4-flat connector.
