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 Hyundai Palisade (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.

The CURT Custom Wiring Harness, 4-Way Flat Output, Select Hyundai Palisade 56491 (Part #BKDK56491) Typical installation time is . Basic hand tools are typically all you need.
Part 56491 is a wiring location guide and powered converter module system for SUVs and vans. It provides instructions for routing trailer wiring through the vehicle and includes a converter module that manages signal and power circuits for trailer lights. The system is designed to work with 12-volt negative ground electrical systems.
Part 56491 is designed for SUVs and vans with 12-volt negative ground electrical systems. The manual does not specify which vehicle makes, models or years are compatible. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle.
No. The converter system is designed only for 12-volt negative ground systems. Do not use it on positive ground vehicles.
You will need: ratchet, 10mm socket, 14mm socket, socket extension, cutting tool, wire stripper, wire crimper, flathead screwdriver, panel trim removal tool, and electrical tape. A fish wire (or substitute such as a cut-up wire hanger, stiff wire, rope or string) is also required to route the harness through blind holes.
The kit includes a custom wiring harness with yellow and green wire housings, a white ground wire with ring terminal, a converter module, two-sided tape, zip ties, a ground screw, a fuse holder with 10-amp fuse, and cable ties for securing the power wire to the vehicle chassis.
Yes. You must disconnect the negative battery terminal in the engine compartment on the driver side before beginning installation. Fasten this wire down and away from the battery while completing the installation process.
Yes. You must remove both the driver side and passenger side taillights. Use a panel trim removal tool to remove the taillight fastener covers, then use a 10mm socket to remove the bolts securing each taillight. Pull the taillight straight back and separate the connectors carefully without damaging the locking tabs.
Fish wire is a tool used to push or pull an electrical wire through a blind hole. It can be a cut-up wire hanger, stiff wire, rope or string. Make sure it is long enough to stick out on the other side of the hole. 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 up. 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.
Starting on the driver side, locate the housing with the yellow wire on the custom wiring harness. From under the vehicle bumper, attach this to the fish wire and pull the harness up to the taillight cavity. Attach the custom wiring harness to the vehicle factory wiring and attach to the taillight. Set the taillight inside the taillight cavity but do not reinstall with hardware yet. Route the housing with the green wire above the bumper and along the bumper to the passenger side of the vehicle, using zip ties as needed. Repeat the process on the passenger side using the housing with the green wire.
Locate a mounting spot for the module and secure it to the vehicle using the supplied two-sided tape and/or zip ties. The manual does not specify a particular location, so choose a spot that is accessible and protected from moisture and damage.
You should first locate an existing grounding point such as an existing screw or bolt in the frame of the vehicle. If no suitable existing fastener is available, you may drill a 3/32-inch pilot hole. Before drilling, the area must be free from rust, dirt and paint—use an abrasive pad or paper to clean it. Always check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and personal injury.
Drill a 3/32-inch pilot hole if an existing grounding point is not available. Before drilling, ensure the area is free from rust, dirt and paint by using an abrasive pad or paper. Always check for hidden items behind or under any surface before drilling.
The wiring harness uses the following color scheme: Yellow = Left turn, Green = Right turn, Red = Brake, Brown = Taillight, and White = Ground. The converter module also includes a black wire that connects to the positive battery terminal and a white ground wire with a ring terminal.
Route a 12-gauge wire or larger 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 black wire to the positive battery terminal using a ring terminal. Secure the power wire to the vehicle chassis using the supplied cable ties. Do not install the fuse until all other steps are complete.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Signal circuits are rated at 3.0 amps per side. Tail and 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.
Disconnect the negative battery terminal before beginning installation. Do not lay tools across the positive battery terminal (typically noted with red covers or a red '+' symbol), as this can cause a ground short resulting in sparks and/or electrical shocks. When routing the power wire, 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. Always check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and personal injury. Do not exceed the product rating or 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 check for proper function.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections.
Part 56491 is designed for SUVs and vans with 12-volt negative ground electrical systems. Confirm compatibility with your specific vehicle make, model and year by contacting Curt Manufacturing or checking a fitment database.
Yes. Disconnect the negative battery terminal in the engine compartment before beginning installation.
Drilling is required only if no existing grounding point is available on the vehicle frame. If drilling is necessary, drill a 3/32-inch pilot hole in a clean, rust-free area.
Use 12-gauge wire or larger to route power from the converter to the vehicle battery.
Signal circuits are rated at 3.0 amps per side; tail and 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.
