Hyundai Tucson (SUVs, Mini & Full-Sized Vans category).
The Curt 56348 is a custom wiring harness that integrates with your Hyundai Tucson's factory taillight wiring to provide trailer lighting connections. It includes a converter box, wiring with colour-coded ends (yellow, green, and white), a 4-flat connector, cable ties, double-sided tape, a ground screw, and a dust cover.
You will need: ratchet, 10mm socket, Phillips screwdriver, wire stripper, wire crimper, and cutting tool. You may also need a drill with a 3/32" bit if a suitable existing grounding point is not available.
The harness includes colour-coded wiring (yellow, green, white), a black converter box, a 4-flat connector, cable ties, double-sided tape, a ground screw with ring terminal, and a 4-flat dust cover.
Signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.

Yes, disconnect the negative battery terminal before starting installation.
Open the tailgate to access the taillight assembly. On the driver side, remove the two fasteners securing the taillight assembly, then gently pull the taillight rearward and out. Behind the taillight, you will find the vehicle taillight wiring harness connectors. Separate these connectors carefully, taking care not to damage the locking tabs.
Route the custom wiring harness end with the yellow wire from underneath the vehicle through the opening under the taillight. Insert this harness end between the separated factory connectors, ensuring the connectors are fully inserted with locking tabs in place. Repeat the process on the passenger side using the harness end with the green wire.
Drilling is required only if a suitable existing grounding point is not available near the taillight connector. If needed, drill a 3/32" pilot hole in a clean area 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.

Mount the black converter box on a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Use the provided double-sided tape to adhere it. Mounting the box in a protected area is critical; failure to do so can cause loss of warranty, product failure, overheating, and potential fire.
