All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Hyundai Tucson and Kia Sportage (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 525 lbs. TW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
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 Kia Sorento and Sportage (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.

Part 56474 is designed for SUVs and Vans with 12-volt negative ground electrical systems. The manual does not list specific vehicle makes, models, or years. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your vehicle before purchasing.
Part 56474 is a wiring harness and powered converter system for SUVs and Vans that provides trailer lighting connections. It includes a converter box, harness connectors with yellow, green, white, and black wires, hardware, double-sided tape, zip ties, and a ground screw. The system converts 12-volt vehicle power to trailer lighting signals.
No. Part 56474 is designed only for 12-volt negative ground systems. Do not use it on positive ground vehicles, as it will not function correctly and may cause electrical damage.
Required tools are: ratchet, wire crimper, 10mm socket, cutting tool, socket extension, wire stripper, panel trim removal tool, electrical tape, and flathead screwdriver. You will also need a fish wire (or substitute such as a cut-up wire hanger, stiff wire, rope or string) to route the harness through blind holes between the bumper and vehicle body.
Yes. You must disconnect the negative battery terminal before beginning installation and fasten this wire down and away from the battery while completing the installation process. This prevents accidental shorts and electrical shock.
The power source for the T-connector power wire connects at the fuse panel on the driver side under the hood. The vehicle battery is internal on this vehicle type. Route 12 GA wire or larger from the converter to the battery location, taking care to avoid pinch points and hot or rotating components.
Open the rear hatch and locate the taillight fastener covers. Use a panel trim removal tool to open the covers. Use a 10mm socket to remove the two bolts securing the taillight in place. Remove the taillight by pulling straight back. Locate the vehicle taillight wiring connectors, which will be similar to those on the custom wiring product. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Repeat on the other side of the vehicle.
Fish wiring is a method to push or pull an electrical wire through a blind hole. For part 56474, route a fish wire down between the rear opening of the bumper cover and body of the vehicle. From under the vehicle bumper, attach the harness connector with the yellow wire to the fish wire using tape and pull the harness up to the taillight cavity. If the fish wire or harness gets hung up, you may need to push back down, wiggle it around, or twist the wire to loosen it. Fish wire can be a cut-up wire hanger, stiff wire, rope or string depending on what is needed.
Route the housing with the green wire above the bumper mount and along the bumper to the passenger side of the vehicle. Zip tie as needed along the bumper. Route above the passenger-side bumper mount. Repeat the fish wire process (Steps 3 and 4) to install the housing with the green wire on the passenger side.
Not necessarily. On the driver side, locate an existing grounding point such as a screw or bolt in the vehicle frame. If no suitable existing fastener is available, you may drill a 3/32" pilot hole. The area should be free from rust, dirt, and paint; use an abrasive pad or paper to remove rust and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. Secure the white ground wire with the ring terminal on the existing fastener or with the provided ground screw.
If an existing grounding point is not available, drill a 3/32" pilot hole. Before drilling, ensure the area is free from rust, dirt, and paint by using an abrasive pad or paper. Always check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and personal injury.
Locate a flat spot on the vehicle. Adhere the black converter box using the provided double-sided tape and/or zip ties. The converter should be mounted in a location where it is secure and protected from moisture and heat.
The wire colors in part 56474 are: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight (running lights), White = Ground, and Black = Power (positive battery connection). The yellow and green wires are housed in separate connectors that attach to the vehicle taillights.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed this rating. The fuse should be installed after all other installation steps are complete. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Signal circuits (left turn, right turn, brake) are rated at 3.0 amps per side. Tail/Running circuits are rated at 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Use 12 GA (12-gauge) wire or larger to route from the converter to the vehicle battery location. Route the wire 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 power wire from sharp edges.
Use a ring terminal for the battery connection. Route the black power wire to the positive battery (+) terminal. The battery connection must be fuse-protected with a 10-amp max fuse. Install the fuse after all other installation steps are complete. Disconnect the negative battery (-) cable before wiring the power wire to avoid shorts.
Disconnect the negative battery terminal and fasten it down and away from the battery. Do not lay tools across the positive battery terminal (typically noted with red covers or a '+' symbol) as this can cause a ground short, sparks, and/or electrical shocks. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. Route the power wire 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 it from sharp edges.
Once the custom harness is installed, verify that it is functioning by attaching the 4-flat connector to any trailer with functioning lights. Test for proper function using a test light or by connecting a properly wired trailer. Ensure all signal circuits (left turn, right turn, brake) and tail/running lights operate correctly.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the battery connection, ground wire, and all harness connectors regularly. Verify that the converter box remains securely mounted and that all zip ties are intact.
The installation difficulty level is rated as Easy. However, installation difficulty levels are based on time and effort involved and may vary depending on the installer's level of expertise, condition of the vehicle, and proper tools and equipment. Before you begin installation, read all instructions thoroughly. Proper tools will improve the quality of installation and reduce the time required.
Part 56474 is designed for SUVs and Vans with 12-volt negative ground systems. Confirm compatibility with your specific vehicle make, model, and year before purchasing.
Yes, disconnect the negative battery terminal before installation and keep it fastened away from the battery throughout the process.
Drilling is optional. You can use an existing ground point on the vehicle frame. If no suitable fastener exists, drill a 3/32" pilot hole for the ground wire. Always check for hidden items before drilling.
The battery connection must use a 10-amp maximum fuse. Do not exceed this rating to prevent overheating and fire.
Use 12 GA (12-gauge) wire or larger to route from the converter to the battery.
