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 Focus. 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 58944 Custom Towed-Vehicle RV Wiring Harness for Dinghy Towing, Fits Select Ford Focus (Part #BKDK58944) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
CURT 58944 is designed for passenger cars with trunk-mounted factory taillight connectors. The installation requires access to the vehicle's factory wiring harness connectors located behind the taillight housings (inside the trunk area). If your vehicle has these connectors and a trunk you can access, the product should fit. Check your vehicle owner's manual or contact the vehicle manufacturer if you are unsure whether your car has the required factory connectors.
The CURT 58944 includes an RV harness with a 4-flat connector, a 4-flat bracket, two screws for the bracket, one screw for the ground wire ring terminal, a white ground wire with ring terminal, a 4-flat dust cover, and cable ties. The manual shows an "Included Parts" section on page 1, though the specific image is not detailed in the text extraction.
You will need a fishwire, utility knife, and flathead screwdriver. The manual also recommends having a drill with a 3/32" bit, sealant, and zip ties (though zip ties are not explicitly listed as required, they are referenced in the installation steps). Proper tools will improve the quality of installation and reduce the time required.
Open the trunk and remove the floor cover. Remove the two push pins on both sides of the threshold and remove it by pulling up. Remove the foam insulation on the left side of the trunk and set aside. Read all instructions thoroughly before beginning. The manual emphasizes that all steps must be followed to ensure the product will function properly.
Pull back the trunk liner to locate the vehicle's factory wiring harness connectors behind the taillight housing. Starting on the driver side, carefully separate the connectors from the taillight housing without damaging the locking tabs. Route the RV harness end with the yellow wire up behind the felt liner and insert it between the separated connectors. Repeat on the passenger side with the RV harness end containing the green wire, routing it along the bottom of the side wall panel and up behind the passenger side panel. Make sure both connectors are fully inserted with locking tabs in place.
Remove the rubber grommet in the trunk area near the felt liner. Cut the cable ties on the 4-flat portion of the RV harness. Route the 4-flat through the grommet opening, then remove the grommet and cut a slit large enough for the RV harness wiring to pass through. Reseat the grommet and use sealant to seal the cut and around all wires. Underneath the vehicle, route the 4-flat wire over the driver side near the rear wheel well and secure it. Continue routing to the front either behind the side trim plate or along brake line brackets. In the engine compartment, use a fishwire down through the front wheel well to pull the 4-flat up and into the engine compartment, positioning it near the front of the vehicle.
Yes, drilling is required in two locations. First, you must drill a 3/32" pilot hole for the ground wire screw at a suitable grounding point near the connector on the vehicle frame. Second, you must drill two 3/32" holes on the frame behind the driver-side taillight to mount the 4-flat bracket. Before drilling, check for miscellaneous items hidden behind or under any surface to avoid damage and personal injury. Take care not to drill through the vehicle body or any exposed surface.
Yes. Remove the rubber grommet in the trunk area near the felt liner, then cut a slit large enough to route the RV harness wiring through. After routing the 4-flat through the grommet opening, reseat the grommet and use sealant to seal the cut in the grommet and around all the wires to prevent water intrusion and corrosion.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Locate a suitable mounting location for the 4-flat bracket on the frame behind the driver-side taillight. Using the bracket as a template, mark two holes and drill two 3/32" pilot holes. Attach the bracket using the two remaining screws provided. Take care not to drill through the vehicle body or any exposed surface.
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.
Signal circuits are rated at 7.5 amps per side. Tail and running circuits are rated at 7.5 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for more information about your vehicle's lamp load capacity.
Avoid areas that contain moving parts or could cut, pinch or burn the wires when routing the 4-flat harness to the front of the vehicle. Failure to follow these warnings may cause property damage, personal injury or loss of life. Before drilling anywhere, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. Do not drill through the vehicle body or any exposed surface.
After installation, test for proper function by using a test light or by connecting a properly equipped tow vehicle. All steps must be followed to ensure the product will function properly. Once tested, 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. Install and maintain the provided 4-flat dust cover to help prevent corrosion. Register your purchase at warranty.curtgroup.com/surveys to receive product updates and warranty information.

Ensure the locking tabs on both the factory connectors and the RV harness connectors are properly aligned and fully inserted. The manual emphasizes that connectors must be fully inserted with locking tabs in place. If they still do not seat, check that you have separated the factory connectors correctly and that the RV harness connectors match the factory connector type. Do not force the connectors, as this may damage the locking tabs.
The manual requires that you use sealant to seal the cut in the grommet and around all the wires after routing the 4-flat through. If water is leaking, the sealant may not have been applied properly or may have degraded. Inspect the grommet area and reapply sealant around the cut and all wires passing through the grommet to prevent water intrusion and corrosion.
