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 Venue (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 Venue Trailer Connector Kit (Part #BKDK56451) Typical installation time is 60-90 minutes. Basic hand tools are typically all you need.
Part 56451 is designed for SUVs and Vans (S-series vehicles). The manual does not list specific vehicle models or years. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make and model to confirm compatibility.
No. The converter system is designed only for 12-volt negative ground electrical systems. Do not use it on 24-volt systems or positive ground vehicles.
The 56451 is a wiring converter system that integrates trailer lighting into your vehicle's electrical system. It connects to your vehicle's taillight wiring and provides a 4-flat connector for trailer use. The system includes a converter box, custom wiring harness with colour-coded wires (yellow for left turn, green for right turn, red for brake, brown for taillight), and a powered lead that connects to your vehicle battery.
You will need: ratchet, 10mm socket, socket extension, cutting tool, wire crimper, wire stripper, flathead screwdriver, heat gun, drill, 3/32" drill bit, and a trim panel removal tool. Proper tools will improve installation quality and reduce time required.
The kit includes: a black converter box, custom wiring harness with yellow, green, red and brown wires, white ground wire with ring terminal, black power wire, 4-flat connector, provided screw for ground connection, double-sided tape for mounting the converter box, cable ties for securing loose wires, 10-amp fuse holder with fuse, and a 4-flat dust cover.
Yes. You must disconnect the negative battery terminal before beginning installation. Disconnect it in Step 1 and keep the wire fastened down and away from the battery. Reconnect it only after all other installation steps are complete and the fuse has been installed.
The installation difficulty is rated as Moderate. This is based on time and effort involved and may vary depending on installer expertise, vehicle condition, and availability of proper tools and equipment.
The taillight wiring connectors are located behind the side trim panels. On the driver side, remove the 10mm bolts securing the side trim panel and use a trim panel removal tool to loosen it. The connectors will be similar to those on the custom wiring harness. Repeat on the passenger side. Take care not to damage alignment tabs or fasteners when removing panels.
Separate the vehicle taillight connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring end with the yellow wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Route the custom wiring end with the green wire to the passenger side along the back of the hatch. Repeat the process on the passenger side using the wiring end with the green wire.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The area should be clean and suitable for mounting.
You may need to drill a 3/32" pilot hole for the ground screw, depending on your vehicle. Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, drill a 3/32" pilot hole. The area must be free of rust, dirt and paint. 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 new grommet, or use silicone to protect the power wire from sharp edges. This prevents damage to the wire insulation and potential electrical hazards.
Signal circuits are rated at 6.0 amps per side. Tail and running circuits are rated at 3.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Use 12 GA (gauge) wire or larger for the power connection from the vehicle battery to the converter. Route the 12 GA wire to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components.
The custom wiring harness uses the following colour code: Yellow = Left turn signal, Green = Right turn signal, Red = Brake, Brown = Taillight. The white wire is the ground wire.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Install the fuse after all other installation steps are complete. Exceeding this rating can cause loss of warranty, overheating and potential fire.
Use a ring terminal for the battery connection. Route the black power wire to the positive battery (+) terminal. The white ground wire should be attached to the vehicle body using the provided screw (drill a 3/32" hole if necessary). Disconnect the negative battery cable before wiring the power wire, and reconnect it only after all other steps are complete and the fuse is installed.
When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Route the 12 GA power wire to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties. 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.
Once the 12-volt power wire is connected to the harness, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. This should be done before final use.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. This helps maintain proper function and safety of the converter system.
The 56451 is designed for SUVs and Vans (S-series). Confirm compatibility with your specific vehicle year, make and model using a fitment database or by contacting Curt Manufacturing.
No. The 56451 works only on 12-volt negative ground electrical systems.
Yes. Disconnect the negative battery terminal before starting installation and reconnect it only after all steps are complete and the fuse is installed.
