All Hardware and Installation Instructions Included!
Whatever the next item is on your to-do list -- whether it's arriving at the jobsite before dawn or getting your travel trailer set up in time to see the sunset -- CURT class 4 trailer hitches offer greater towing power to let you Bring It. These custom receiver hitches are built to tackle bigger jobs and bolder adventures, all while giving you a custom fit for your vehicle. Class 4 hitches are available for a variety of makes and models, from pickup trucks and SUVs to full-size and commercial vans. This particular class 4 hitch fits certain years of the Ford F150 (to verify vehicle compatibility, see application info). It provides a weight carrying capacity of 10,000 lbs. GTW and 1,000 lbs. TW. It can also accept a weight distributing hitch, offering a maximum WD capacity of 12,000 lbs. and a WDTW of 1,200 lbs. CURT class 4 tow hitches are as much suited for work as they are for play. With their high load capacities, they are typically used for towing larger trailers, including everything from a double-axle utility trailer or livestock trailer to a full-length camper or large boat trailer (NOTE: Never exceed the lowest weight capacity of any towing component). All CURT class 4 receiver hitches come with a 2" receiver tube opening and all the necessary hardware for a complete installation. From light-duty to heavy-duty, every CURT custom hitch is engineered to be vehicle-specific, using actual vehicles to create the optimal design. We then combine high-strength steel, precise welding and a co-cured finish of liquid A-coat and durable black powder coat to provide you with a hitch you can depend on. To prove it, we test all our hitches in accordance with SAE J684 for safety.
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Ford F-150 with LED taillights (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

All 5/8" fasteners (the carriage bolts and hex flange nuts) must be torqued to 210 lb-ft. Use a torque wrench to ensure this specification is met.
Fishwiring is a technique used to thread fasteners through the frame rails where direct access is not available. In step 2, you thread the forward-most fishwires through a rectangular spacer on each side, then thread all fishwires through their appropriate mounting holes. In step 3, you fishwire 2 carriage bolts and spacers through either an access hole or the end of the frame rail, leaving them in the frame with the fishwires attached. In step 4, you pull the fishwires to position the bolts, then carefully remove the fishwires.
1. Remove the grounding cable from the passenger side frame rail if present, and lower the spare tire. 2. Tape U-shaped spacers into the recess in the frame at the rearward-most holes, and thread fishwires through rectangular spacers and mounting holes. 3. Fishwire carriage bolts and spacers through access holes or frame rail ends on both sides. 4. Raise the hitch into position, pull fishwires to position the bolts, remove fishwires, and loosely install hex flange nuts. Reinstall the grounding cable with the M8 fastener. 5. Torque all 5/8" fasteners to 210 lb-ft and raise the spare tire back into position.
After installation, verify that all fasteners are tight and all structural components are sound. Periodically check the receiver hitch to ensure all fasteners remain tight and all structural components remain sound during the life of the product.

The Curt 56481 is a powered converter wiring harness that converts vehicle taillight signals to a 4-flat trailer connector. It allows you to connect a trailer with functioning lights to your truck, so the trailer lights operate in sync with your vehicle's brake, turn, and running lights. The system includes a converter box, wiring harness with color-coded wires (yellow for left turn, green for right turn, red for brake, brown for taillight), and a 4-flat connector for the trailer.
The Curt 56481 is designed for trucks and is compatible with 12-volt negative ground electrical systems only. The manual shows wiring locations for trucks (T1–T5) behind taillight housings and rear bumper areas. However, the manual does not specify compatibility by year, make, model, bed length, cab style, or drivetrain. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle.
No. The Curt 56481 is designed for 12-volt negative ground systems only. Do not use this converter on 24-volt systems or positive ground systems.
You will need: ratchet, drill, 8mm socket, 3/32" drill bit, socket extension, fishwire (or equivalent such as a cut-up wire hanger, stiff wire, rope or string), and a cutting tool. Proper tools will improve installation quality and reduce time required.
The kit includes: a powered converter box, color-coded wiring harness (yellow, green, red, brown, white), a 4-flat connector with dust cover, double-sided tape for mounting the converter box, cable ties (zip ties) for securing wires, a ground screw with ring terminal, a fuse holder with 10-amp fuse, and butt connectors. Refer to the Hardware Photo on page 1 for visual identification.
Yes. You must disconnect the negative battery terminal before beginning installation. Locate the battery in the engine compartment on the passenger side, disconnect the negative terminal, and fasten the wire down and away from the battery. Reconnect the negative terminal only after all other installation steps are complete and before installing the 10-amp fuse.
Yes. You must remove both taillights to access the taillight wiring connectors. Open the tailgate and use an 8mm socket to remove the two bolts securing each taillight in place. Carefully remove each taillight straight back from the vehicle, locate the wiring connectors, and separate them from the taillight housing without damaging the locking tabs. Set the taillights aside in a safe place.
Fishwire is a method to push or pull electrical wire through a blind hole. Make sure the wire is long enough to stick out on the other side. Insert the fishwire through the blind hole and locate it on the other side. Use tape to secure the harness to the fishwire and pull back up. If the fishwire or harness gets hung up, you may need to push back down, wiggle it around, or twist the wire to loosen it. Fishwire can be anything from a cut-up wire hanger, stiff wire, rope, or string depending on what is needed.
1. Drop the fishwire down into the taillight cavity opening on the driver side. 2. From under the vehicle, attach the custom wiring end with the yellow wire to the fishwire and pull up into the taillight cavity. 3. Attach the custom wiring harness to the vehicle taillight harness. 4. Attach the factory harness to the taillight and the T-end in the custom wiring harness. 5. Route the green wire over to the passenger side, zip-tying as needed along the rear bumper. 6. Repeat the process on the passenger side using the green wire.
Locate a flat spot on the vehicle and adhere the black converter box using the provided double-sided tape and/or zip ties. The manual does not specify exact mounting locations, so choose a protected area away from heat sources, moving parts, and moisture.
Locate a grounding point such as an existing screw or bolt in the frame of the vehicle. If no suitable point exists, drill a 3/32" pilot hole. The area must be free from rust, dirt, and paint—use an abrasive pad or paper to remove rust and paint. Secure the white ground wire with the ring terminal on the existing fastener or with the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Route the 4-flat along the rear bumper, using cable ties as needed to secure any loose wires. Mount the 4-flat near the receiver tube. Install the provided 4-flat dust cover to help prevent corrosion.
Drilling is required only if you do not have an existing screw or bolt suitable for grounding the white ground wire. You will need to drill a 3/32" pilot hole in the vehicle frame. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area must be free from rust, dirt, and paint.
Drill a 3/32" pilot hole for the ground screw. The area must be free from rust, dirt, and paint—use an abrasive pad or paper to clean it. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
No permanent modifications are required. The converter box is mounted using double-sided tape and/or zip ties. The only drilling required is a 3/32" pilot hole for the ground wire, which is a minor modification. All other components are routed along existing surfaces (rear bumper, taillight cavities) without cutting, trimming, or welding.
Signal circuits (left and right turn): 5.0 amps per side. Tail/Running circuits: 7.5 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Use an 8mm socket to remove the two bolts securing each taillight in place. A socket extension may be helpful depending on the taillight design.
Yellow = Left turn signal. Green = Right turn signal. Red = Brake signal. Brown = Taillight (running light). White = Ground. These color-coded wires connect to the corresponding circuits in your vehicle's taillight harness and the trailer connector.
Route the black 12-gauge power wire from the converter to the vehicle battery location, taking care to avoid pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges. Connect the power wire to the positive (+) battery terminal using a ring terminal and butt connector. The battery connection must be protected by a 10-amp fuse (installed in the fuse holder after all other steps are complete). Disconnect the negative battery terminal before wiring the power wire.
Use a 10-amp fuse maximum. The battery connection must be fuse-protected with a 10-amp max fuse. Install the fuse after all other installation steps are complete. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
T1: Behind driver side taillight housing. T2: Behind passenger side taillight housing. T3: Behind driver side rear bumper. T4: Behind center of rear bumper fascia. T5: Behind passenger side rear bumper. These locations are where you will find the vehicle's taillight wiring connectors to connect the Curt 56481 harness.
If the converter is used as a powered module for a two-wire system, the red brake wire must be grounded. Consult the converter documentation or contact Curt Manufacturing for specific instructions on two-wire system configuration.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges. Route the power wire to the battery location taking care to avoid pinch points and hot or rotating components. Disconnect the negative battery terminal before wiring the power wire. Do not exceed the product rating or tow vehicle lamp load rating. Secure the power wire to the vehicle chassis using the provided cable ties.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. The manual does not specify a maximum lamp load rating for the converter itself. Consult your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating.
Once the custom harness is installed, verify that it is functioning by attaching the 4-flat connector to any trailer with functioning lights. The taillights on the vehicle to be towed should function along with the taillights on the vehicle that is powering them. You can also use a test light to verify proper function of each circuit (left turn, right turn, brake, and running lights).
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the 4-flat connector and dust cover regularly to prevent corrosion. Inspect cable ties and mounting tape to ensure all components remain secure.
Yes. Install the provided 4-flat dust cover to help prevent corrosion. The dust cover protects the connector from moisture and environmental damage.
