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 Kia Niro (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 Niro (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.

Yes, the CURT 13329 is designed for 2017-present Kia Niro CUVs. This is a weight-carrying hitch with a maximum trailer weight capacity of 3,500 lbs. and a tongue weight capacity of 525 lbs. Always verify that your vehicle's towing capacity meets or exceeds these limits before towing.
Yes. The CURT 13329 is compatible with 2017-present Kia Niro models, which includes 2020 and later model years.
The CURT 13329 is rated for a maximum trailer weight of 3,500 lbs. and a tongue weight of 525 lbs. when used as a weight-carrying hitch. You must not exceed your vehicle manufacturer's recommended towing capacity.
You will need: a ratchet, torque wrench, 6-inch socket extension, 12mm socket, 16mm socket, 11/16-inch socket, masking tape, aviation shears, and safety glasses. Proper tools will greatly improve the quality of the installation and reduce the time required.
No. The CURT 13329 requires no drilling. The hitch uses existing weld nuts on the frame rails and reverse fishwire hardware to secure the attachment points.
Yes. You must mark out and trim a 3-inch by 5-inch section of the plastic panel using masking tape and aviation shears. The manual instructs you to confirm the trim prior to reinstallation. This is a permanent modification to the vehicle's plastic panel.
You will need to temporarily lower the exhaust. This is done by removing 4 bolts securing the metal exhaust guard using a 12mm socket, and then removing 3 rubber exhaust isolators (one on the driver side, one on the passenger side, and one in the center). The exhaust guard bolts should be returned to the customer. The exhaust is then reinstalled after the hitch is secured.
Two people may be required to ease installation. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
1. Remove the 4 bolts securing the metal exhaust guard and lower the exhaust by removing 3 rubber isolators. 2. Remove plastic push pins and nuts, then trim a 3" × 5" section of the plastic panel. 3. Remove rubber plugs from each frame rail and reverse fishwire the 7/16" carriage bolts and spacers through the access holes. 4. Raise the hitch into position and feed fishwires through the center hole, then loosely secure with 7/16" hex flange nuts. 5. Install the 4 M10-1.25 hex bolts and 4 conical tooth washers (2 on each side). 6. Torque all hardware and reinstall the exhaust and plastic panel in reverse order.
Torque all M10-1.25 hex bolts to 45 ft-lbs. Torque all 7/16-inch hex flange nuts to 59 ft-lbs. These fasteners are located on both sides of the hitch.
The kit includes: 4 M10×1.25 hex cap screws (part 10-10271), 4 conical tooth washers 3/8-inch (part 30-00148), 2 7/16-inch carriage bolts (part 10-10281), 2 7/16-inch serrated flange nuts (part 20-00103), 2 square hole spacers 0.250 × 0.88 × 2.25 inches (part CM-SP2), and 2 pieces of 7/16-inch fishwire (part 7_16 FISHWIRE).
Reverse fishwire refers to feeding the 7/16-inch carriage bolts and CM-SP2 spacers through the access holes in the frame rails from the inside of the vehicle. The fishwire is a tool used to guide these fasteners through the frame rail access holes. After the hitch is positioned, the fishwires are removed and the bolts are secured with 7/16-inch hex flange nuts.
You should loosely secure the 7/16-inch hex flange nuts after feeding the fishwires through the center hole of the hitch (step 4). Then install the M10-1.25 hex bolts and conical tooth washers (step 5). Finally, torque all M10 hardware to 45 ft-lbs. and all 7/16-inch hardware to 59 ft-lbs. (step 6).
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. The manual does not specify a retorque interval, so contact CURT technical support at 877-287-8634 for guidance on maintenance intervals.
Safety glasses must be worn at all times while installing this product. Read all instructions thoroughly before beginning installation. Never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.

The Curt 56376 is a custom wiring harness that integrates trailer lighting circuits with your vehicle's electrical system. It provides signal circuits rated at 3.0 amps per side and tail/running circuits rated at 6.0 amps total, allowing you to connect a trailer with a 4-flat connector.
Yes, the Curt 56376 is designed for the Kia Niro. The installation instructions are specific to this model and include detailed steps for accessing the taillight connectors and interior trim panels on this vehicle.
The manual only confirms fitment for the Kia Niro. Do not assume it fits other Kia models. Contact Curt Manufacturing or check the fitment database for compatibility with other vehicles.
You will need: ratchet, ratchet extension, 10mm socket, Phillips screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool. A drill may be needed if a suitable grounding point with an existing screw is not available.
The harness includes: custom wiring harness with yellow and green wire ends, white ground wire with ring terminal, provided screw for grounding, black converter box with double-sided tape, 4-flat connector with dust cover, and cable ties for securing loose wires.
You must remove: all trunk floor coverings and storage trays, the rear scuff panel (secured by Phillips screws), the lower interior side trim panel fasteners, and the upper side trim panel (using a panel trim removal tool). The taillight wiring harness connectors are located behind the interior side panel, wrapped in foam tape.
Remove the foam tape from the vehicle's taillight wiring harness connectors and separate them from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
The yellow wire end connects to the driver side taillight connector, and the green wire end connects to the passenger side taillight connector. The green wire end is routed down behind the interior side panel and out to the passenger side to complete the installation on both sides of the vehicle.
Drilling may be required for the ground wire installation. You must locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you must drill a 3/32" pilot hole. The area must be free of rust, dirt and paint before securing the white ground wire with the ring terminal and provided screw.
Drill a 3/32" pilot hole if a suitable existing screw with nut is not available in the vehicle frame near the taillight connector.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower, to avoid loss of warranty, overheating and potential fire.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route it to the center of the vehicle and out of the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
Locate a flat spot near the taillight wiring harness that is out of the way of the side trim panels. Adhere the black converter box using the provided double-sided tape.
Secure any loose wires with the provided cable ties. This helps keep the installation neat and prevents wires from interfering with trim panels or other components.
The battery connection must be fuse-protected with a 10-amp maximum. Exceeding this can cause loss of warranty, overheating and potential fire.
Test for proper function using a test light or by connecting a properly wired trailer.
