CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Hyundai Palisade, Hyundai Santa Fe, Hyundai Tucson, Kia Telluride and Kia Carnival (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

The CURT Custom Wiring Harness, 4-Way Flat, Select Hyundai, Kia, Tow Package Needed Trailer Connector Kit (Part #BKDK56420) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
CURT part 56420 is designed for SUVs and vans classified as S-series vehicles. The manual does not list specific vehicle makes, models, or years. Contact CURT or consult a fitment database to confirm compatibility with your exact vehicle before purchasing.
CURT 56420 is a custom wiring harness for SUVs and vans that connects the vehicle's factory electrical system to a trailer connector. It includes a converter box, 4-flat connector, fuse holder, and cable ties. The harness allows you to power trailer lights and signals from your vehicle's existing lighting circuits.
You will need: a ratchet, a 14mm socket, a socket extension, a panel trim removal tool, and a cutting tool. These are the minimum tools required for installation.
Yes. Step 1 requires you to locate the vehicle battery on the driver side in the engine compartment and disconnect the negative terminal. Fasten this wire down and away from the battery during installation. Reconnect it in Step 5 after all other work is complete.
The battery connection must be fuse-protected with a maximum of 15 amps. The fuse is provided in the kit and must be installed into the fuse holder in the custom wiring harness during Step 3. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
The manual does not provide a specific torque value for the 14mm bolts. It states only that the 14mm nuts on the shroud are push nuts and should be tightened so they do not cause noise. Contact CURT for the exact torque specification.
Signal circuits are rated at 5.0 amps per side. Tail and running circuits are rated at 7.5 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
The wiring harness is installed behind the driver side rear bumper (location S5). The converter box is adhered to a flat spot near the factory harness area using provided double-sided tape. The 4-flat connector is routed along the back of the vehicle to the hitch.
In Step 3, remove the dust cover from the harness without damaging the locking tabs. Insert the custom wiring harness end into the OEM (factory) harness. Make sure the connectors are fully inserted with locking tabs in place. Then install the provided fuse into the fuse holder in the custom wiring harness.
In Step 2, locate the plastic shroud below the driver-side rear bumper cover. Remove three push fasteners and two 14mm bolts (which are attached to the shroud). These bolts are push nuts and should be tightened so they do not cause noise when reinstalled.
In Step 4, route the 4-flat connector along the back of the vehicle to the hitch. Secure any loose wires with the provided cable ties to prevent movement and damage.
The black converter box is part of the CURT 56420 harness assembly. In Step 4, locate a flat spot near the factory harness area and adhere the converter box using the provided double-sided tape. This box converts the vehicle's factory lighting signals to the 4-flat trailer connector format.
Do not lay tools across the positive terminal (typically labeled with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks. After disconnecting the negative terminal in Step 1, fasten this wire down and away from the battery during the entire installation.
After installation, test for proper function by using a test light or connecting a properly wired trailer. This will verify that all signal and running circuits are functioning correctly before towing.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Install the provided 4-flat dust cover to help prevent corrosion.
The kit includes a custom wiring harness with connector, a converter box, a 4-flat connector with dust cover, a fuse (15-amp max), a fuse holder, double-sided tape, and cable ties. All components are needed for proper installation.
CURT 56420 is designed for SUVs and vans (S-series vehicles). Consult a fitment database or contact CURT to confirm compatibility with your specific vehicle make, model, and year.
Yes. Disconnect the negative battery terminal before starting installation and reconnect it after all work is complete.
No drilling is required. The converter box is adhered using provided double-sided tape, and the harness connects to the factory connector without drilling.
Do not exceed the product rating or tow vehicle lamp load rating. Do not lay tools across the positive battery terminal, as this can cause sparks or electrical shocks.
Periodically inspect all wires and connections for visible damage or loose connections. Install the provided 4-flat dust cover to prevent corrosion.
