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 Ram 1500. 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.

Ratchet, socket extension, cutting tool, Torx T-20 bit, fish wire (or stiff wire/rope), panel trim removal tool, and electrical tape. An abrasive pad or paper is also needed to clean the grounding surface.
Yes. Disconnect the negative battery terminal at the start of installation and fasten the wire down and away from the battery. Reconnect it after all wiring is complete.
Drilling may be required for the ground wire. If no existing screw or bolt is available near the taillight box, drill a 3/32" pilot hole in the vehicle frame. Before drilling, check for hidden items behind or under any surface to avoid damage.
Verify the harness functions by attaching the 4-flat connector to any vehicle with functioning trailer lights. The taillights on both the tow vehicle and towing vehicle should function. Perform periodic inspection of all wires and connections for visible damage or loose connections.
CURT 58975 is a custom wiring harness that connects your truck's factory taillights to a 4-flat trailer connector. It allows your trailer lights to function when towing. The harness includes yellow and green wire housings for driver and passenger sides, a white ground wire, and a 4-flat connector for the trailer.
The harness includes: yellow wire housing (driver side), green wire housing (passenger side), white ground wire with ring terminal, 4-flat connector, ground screw, and 4-flat dust cover. The manual does not specify quantities or additional hardware.
The manual does not specify compatible vehicle makes, models, or years. It is designed for trucks with factory taillights accessible from the tailgate and an inner fender suitable for 4-flat mounting. Verify fitment with CURT or your retailer before purchase.
The manual rates the installation as 'Easy' but does not provide a specific time estimate. Installation time depends on your familiarity with vehicle wiring, access to the taillight and engine compartment, and whether drilling is required.
The manual rates installation as 'Easy' and does not require professional installation. However, if you are unfamiliar with vehicle wiring, electrical connections, or drilling, professional installation is recommended. All steps must be followed to ensure proper function.
Open the tailgate. Use a panel trim removal tool to remove four push fasteners and four T-20 Torx bit screws (two per side) mounted near the taillight in the sidewall covered by the closed tailgate. Carefully remove the taillight straight back and out of the vehicle.
Separate the factory harness connectors from the taillight housing, taking care not to damage the locking tabs. Attach the yellow wire housing (driver side) and green wire housing (passenger side) to the respective factory connectors, ensuring each connector is fully inserted with locking tabs in place.
Fish wire is a tool to push or pull electrical wire through blind holes. It can be a cut-up wire hanger, stiff wire, rope, or string. Insert it through the blind hole until it protrudes on the other side. Secure the harness to the fish wire with tape and pull it back through. If it gets hung up, push back, wiggle, or twist to loosen it.
Route the 4-flat along the driver-side frame rail, securing with loosely-fastened zip ties. Route between the frame and fuel tank to the front of the vehicle and up to the rear of the front tire. From under the hood, use fish wire to pull the harness up between the inner and outer fender to the top of the engine compartment.
Mount the 4-flat to the driver-side inner fender between the fuse panel and the headlight. Route the wire along the driver-side inner fender under the trim cover, then to just behind the passenger-side headlight and mount to the inner fender.
Use zip ties to secure the harness along the frame rail and inner fender, keeping it away from hot spots, pinch points, and moving objects. Loosely fasten zip ties initially, then tighten after removing slack. Do not over-tighten, as this can cause wire breakage. Secure excess wire so it is not drooping or dangling.
If no existing fastener is available, drill a 3/32" pilot hole in the vehicle frame near the taillight box for the white ground wire. Before drilling, check for hidden items behind or under any surface to avoid damage.
Locate a grounding point near the taillight box, such as an existing screw or bolt in the vehicle frame. Clean the area of rust, dirt, and paint using an abrasive pad or paper. Secure the white ground wire with its ring terminal to the existing fastener or to the provided ground screw.
Yellow wire housing connects to the driver-side taillight. Green wire housing connects to the passenger-side taillight. White wire is the ground wire that must be secured to a clean, rust-free point on the vehicle frame.
The 4-flat connector is the trailer connector that mounts to the vehicle. It connects the truck's taillight wiring to a trailer's lights. After installation, verify function by attaching it to any vehicle with functioning trailer lights. A dust cover is provided to prevent corrosion.
The manual does not specify a weight or towing capacity. It states: do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Refer to CURT's product specifications or your vehicle owner's manual for capacity details.
Disconnect the negative battery terminal before starting. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury. Ensure the ground wire is secured to a clean, rust-free, paint-free surface. Do not over-tighten zip ties, as this can cause wire breakage.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Install the provided 4-flat dust cover to help prevent corrosion. Check connections regularly, especially before towing.
Verify the harness is functioning by attaching the 4-flat connector to any vehicle with functioning trailer lights. The taillights on both the tow vehicle and towing vehicle should function. If they do not, check all connections for proper seating and locking tabs.
1. Verify the 4-flat connector is fully seated and locked to the trailer connector. 2. Check that the yellow and green wire housings are fully inserted into the factory taillight connectors with locking tabs in place. 3. Ensure the white ground wire is securely fastened to a clean, rust-free point on the vehicle frame. 4. Inspect all wires and connections for visible damage or loose connections. 5. Test with a properly wired trailer to confirm function.
Secure excess wire so it is not drooping or dangling by using zip ties to fasten it to a solid spot along the driver-side inner fender or frame rail. Do not over-tighten the zip ties, as this can cause wire breakage. Ensure the harness is routed away from hot spots, pinch points, and moving objects.
The manual warns to take care not to damage the locking tabs when separating the factory connectors. If tabs are damaged, the connector may not seat properly and the harness will not function. Contact CURT or a dealer for a replacement factory connector or harness.
