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 2500 and 3500. 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 Ram 2500, 3500 Trailer Connector Kit (Part #BKDK58994) fits 2013-2018 Ram 2500 models. The 2018 model year is the last year covered by this part number. For newer models, check for an updated version.
The CURT Custom Towed-Vehicle RV Wiring Harness, Select Ram 2500, 3500 Trailer Connector Kit (Part #BKDK58994) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The 58994 is designed for trucks with accessible taillight housings on both driver and passenger sides and a rear bumper area. The manual does not specify vehicle makes, models, or years. Verify fitment by checking that your truck has taillight housings that can be accessed from behind and a rear bumper structure matching the wiring location guide shown in the manual.
You will need: ratchet, socket extension, panel trim removal tool, fish wire (or equivalent such as a cut-up wire hanger or stiff wire), T-25 Torx bit, and a cutting tool. An abrasive pad or paper is also needed to clean rust and paint from the grounding point.
Yes. Step 1 requires you to locate the vehicle battery and disconnect the negative battery terminal before beginning installation. On gas engines the battery is on the driver side; on diesel engines batteries are on both sides. Fasten the disconnected wire down and away from the battery during installation.
Drilling may be required. Step 5 instructs you to locate an existing screw or bolt in the vehicle frame for the ground wire, or drill a 3/32" pilot hole if no suitable existing fastener is available. Before drilling, check for hidden items behind or under any surface to avoid damage or injury.
Drill a 3/32" pilot hole if you do not have an existing screw or bolt to use as a grounding point. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it before securing the white ground wire with the ring terminal.
The harness includes a yellow wire (routed up to the driver-side taillight cavity), a green wire (routed to the passenger side along the rear bumper), a white ground wire (secured to a frame grounding point), and a 4-flat connector (routed to the front of the vehicle under the hood). The manual does not specify colours for the 4-flat connector wires.
The Curt 58994 is a trailer wiring harness that allows you to connect a trailer to your truck's electrical system. It routes wiring from the truck's taillights to a 4-flat connector mounted in the engine compartment, enabling the trailer lights to function when connected. The harness includes custom wiring that integrates with the factory taillight harnesses on both sides of the truck.
The manual rates the installation difficulty as 'Easy', based on time and effort involved. However, difficulty may vary depending on your experience level, the condition of your vehicle, and whether you have the proper tools. The installation requires disconnecting the battery, removing taillights, routing wiring through the vehicle frame and engine compartment, and securing a ground connection.
Yes. Step 2 instructs you to lower the tailgate before removing the taillight fasteners on both sides of the vehicle. This provides access to the taillight housings.
Lower the tailgate. Use a T-25 Torx bit to remove the taillight fasteners on both sides of the vehicle. Pull the taillight straight back out of the vehicle. Carefully separate the upper connectors, taking care not to damage the locking tabs. Set the taillight aside and repeat on the other side.
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 58994, you use fish wire to route the yellow wire from the bottom up to the driver-side taillight cavity, and later to route the 4-flat harness down the inner fender. Insert the fish wire through the blind hole, locate it on the other side, use tape to secure the harness to the fish wire, and pull back. 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.
On the driver side, use a fish wire to route the yellow wire up from the bottom to the taillight cavity. Install the custom wiring harness with the yellow wire positioned between the factory harness. Follow the fish wire technique described in the manual: insert the fish wire through the blind hole, secure the harness to it with tape, and pull back up. If the wire gets hung up, push back down, wiggle, or twist to loosen it.
Route the harness connector with the green wire to the passenger side of the vehicle along the rear bumper. Loosely secure it with zip ties, leaving room for adjustments until the harness has been fully installed to the factory harness. Then repeat the fish wire process on the passenger side (as described in Step 3) to install the harness into the factory wiring.
Locate a grounding point such as an existing screw or bolt in the vehicle frame. If no suitable existing fastener is available, drill a 3/32" pilot hole. 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. Before drilling, check for hidden items behind or under any surface to avoid damage or injury.
Route the 4-flat along the driver-side frame rail up to the rear of the front tire, loosely securing with zip ties. Once the harness is just behind the driver-side front wheel, route it to the rear of the driver-side wheel well. Using a fish wire, route the harness down along the inner fender and fire wall. From under the vehicle, pull back the inside of the wheel well lining and inner fender. Once the wire is at the bottom of the panel, pull the harness up into the engine compartment. Finally, route the 4-flat along the driver-side inner fender and mount it in the front of the vehicle under the hood.
No. During installation, loosely secure the harness with zip ties, leaving room for adjustments until the harness has been fully installed. Only after removing slack from the 4-flat wire and completing all routing should you tighten the zip ties and add additional ones as needed. 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.
After routing the 4-flat harness to the front of the vehicle under the hood, secure any excess wire so it is not drooping or dangling, but not so tight that it causes strain. Tighten any zip ties and add additional ones 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.
Once the RV harness is installed, verify that it is functioning by attaching the 4-flat connector 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. The manual does not specify an inspection interval. Install the provided 4-flat dust cover to help prevent corrosion.
Disconnect the negative battery terminal before beginning installation and fasten the disconnected wire down and away from the battery. Do not lay tools across the positive battery terminal (typically marked with red covers or a red '+' symbol), as this can cause a ground short, sparks, or electrical shocks. Before drilling, check for hidden items behind or under any surface to avoid damage or personal injury. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
Laying tools across the positive battery terminal (typically marked with red covers or a red '+' symbol) can cause a ground short, which can result in sparks and/or electrical shocks. Always keep tools away from the positive terminal during installation.
Secure excess wire so 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. During installation, use loose zip ties to allow for adjustments. Only tighten them after all routing is complete and slack has been removed from the 4-flat wire.
