All Hardware and Installation Instructions Included!
However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Hyundai Kona (except EV or N; to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.
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 Kona (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, CURT 11529 is designed for 2018-Present Hyundai Kona SUV models. The hitch is a weight-carrying receiver hitch rated for a maximum of 2,000 lbs trailer weight and 200 lbs tongue weight. Always verify your vehicle's manufacturer towing capacity before towing, as you must never exceed it.
Yes, CURT 11529 fits both AWD and RWD Hyundai Kona models. However, AWD models require an additional step: the exhaust must be lowered by removing 2 rubber isolators before installation and raised back into position after torquing the hitch fasteners. RWD models do not require this exhaust work.
CURT 11529 is designed for use with ball mount #45521. Euro mount options are also available: #45571 (1 7/8" ball) or #45572 (2" ball). Consult the CURT catalog or website at www.curtmfg.com for compatibility and specifications of these ball mounts.
CURT 11529 includes: 4 bolts (7/16-14 UNC, 1-1/4", Grade 8, part 10-10281); 4 serrated flange nuts (7/16-14 UNC, Grade 8, part 20-00103); 4 pieces of 7/16" fishwire (part 7_16 FISHWIRE); and 4 spacers (part 11529-SP). All fasteners are Grade 8 and zinc-plated.
Required tools: screwdriver, 10mm socket, 11/16" socket, 6" socket extension, ratchet, torque wrench, and safety glasses. The manual notes that using proper tools will greatly improve installation quality and reduce installation time.
No. CURT 11529 is a no-drill installation. The hitch uses the fishwire method to route fasteners through existing lower holes in the outside of the frame rails, eliminating the need for drilling.
No electrical wiring is required. However, the electrical harness must be relocated from under the driver side of the bumper beam to above the bumper beam as part of Step 1 of the installation process. This is a repositioning task, not an electrical modification.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and notes that 2 people may be needed, though it does not state this is mandatory for all installations.
1. Move the electrical harness from under the driver side bumper beam to above it. Remove the underbody panel from the passenger side frame rail and save it. 2. On AWD models only, lower the exhaust by removing 2 rubber isolators. 3. Fishwire the 7/16" carriage bolts and spacers into the lower holes in the outside of the frame rails. 4. Raise the hitch into position, feeding fishwires through the hitch holes, and loosely secure with 7/16" hex flange nuts. 5. Torque the 7/16" hardware to 59 lb-ft, raise the exhaust back into place (AWD only), and reinstall the panel.
Fishwire is a method of routing fasteners through existing holes without drilling. For CURT 11529, you thread the 7/16" fishwire (included) through the lower holes in the outside of the frame rails, then feed the 7/16" carriage bolts and spacers through the fishwire to position them in the frame. This allows the hitch to be installed without creating new holes.
No. After raising the hitch into position and feeding the fishwires through the hitch holes, you should loosely secure the fasteners with the 7/16" hex flange nuts. Only after all fasteners are in place should you torque them to the final specification of 59 lb-ft.
All 7/16" hardware (bolts and hex flange nuts) must be torqued to 59 lb-ft. This torque is applied after the hitch is positioned and all fasteners are loosely secured.
CURT 11529 is rated for a maximum of 2,000 lbs trailer weight and 200 lbs tongue weight. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower. Always verify your Hyundai Kona's towing limits before towing.
No. All non-trailer (wheel-less) loads applied to this hitch must be supported by CURT 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. See the CURT catalog or visit www.curtmfg.com for information on the 18050 stabilizing straps.
Safety glasses must be worn at all times while installing this product. If you are hesitant to undertake the installation yourself, contact an authorized CURT installer for assistance. You can reach CURT technical support at 877-287-8634 for help or questions.
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, but regular inspection is recommended to maintain safe operation.
Yes. CURT Manufacturing warrants this product to be free of defects in material and workmanship at the time of retail purchase by the original purchaser. If defective, CURT may repair or replace the product at their option when returned prepaid with proof of purchase. Warranty is voided by alteration, misuse, or improper installation.

CURT 56409 is a custom wiring harness with a powered converter system designed for passenger cars. It provides signal circuits (3.0 amps per side) and tail/running circuits (6.0 amps total) to enable trailer lighting or other auxiliary lighting functions. The system includes a black converter box that mounts inside the vehicle near the taillight, a power lead that connects to the vehicle battery, and wiring harnesses that connect to the vehicle's existing taillight connectors.
CURT 56409 is designed for passenger cars with 12-volt negative ground electrical systems. The manual shows wiring locations for passenger cars (P1–P7) and notes that battery location may differ depending on the vehicle. You should verify compatibility with your specific vehicle model before purchase. Consult the vehicle owner's manual or contact the vehicle manufacturer for confirmation.
No. The manual explicitly states that this converter system is to be used only on 12-volt negative ground systems. It is not compatible with 24-volt systems or positive ground systems.
The following tools are required: ratchet, ratchet extension, socket (1/4"), Phillips screwdriver, side cutter, wire crimper, wire stripper, panel trim removal tool, and utility knife. Proper tools will improve the quality of installation and reduce the time required.
The kit includes: a black converter box, a 12-gauge power wire with ring terminal for battery connection, a white ground wire with ring terminal, a provided screw for grounding, cable ties for securing wires, provided double-sided tape for mounting the converter box, a grommet sealant, a 4-flat dust cover, and a fuse holder with 10-amp fuse (to be installed after all other steps are complete). The kit also includes wiring harnesses with red, yellow, green, and brown wires for connection to vehicle taillight connectors.
Yes. The manual explicitly states: "Disconnect negative battery (-) cable before wiring the power wire." This is a required safety step before beginning the power wire installation. After all other installation steps are complete and the fuse is installed, you may reconnect the negative battery terminal.
The manual rates the installation difficulty as "Easy." However, the installation involves multiple steps including removing trim panels, accessing taillight connectors, routing wires through the vehicle, drilling a pilot hole for grounding, and making electrical connections. You should read all instructions thoroughly before beginning.
The installation follows these main steps: (1) Open trunk and remove floor coverings; (2) Remove rear scuff panel; (3) Remove driver-side trim panel fasteners and locate taillight connectors; (4) Insert custom wiring with red wire between separated connectors; (5) Remove grommet from taillight wiring harness; (6) Cut slit in grommet and route yellow and green wires through; (7) Locate and separate passenger-side taillight turn signal connector and insert yellow wire; (8) Repeat steps 5–7 on passenger side with green wire; (9) Locate grounding point and secure white ground wire; (10) Mount converter box and route power wire from battery. All steps must be followed to ensure proper function.
Locate the vehicle's taillight wiring connectors behind the taillight housing. The connectors will be similar to those on the custom wiring product. Carefully separate the connectors without damaging the locking tabs. Insert the custom wiring end (with the appropriate wire colour: red for brake, yellow for left turn, green for right turn) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process for both driver and passenger sides.
Route the custom wiring end with yellow and green wires out through the grommet opening and through a slit cut in the grommet from the trunk to the taillight connector. Remove the grommet from which the vehicle taillight wiring harness passes through from inside the trunk to underneath the vehicle. Cut a slit large enough to route the new custom wiring through. After routing, reseat the grommet and use the provided sealant to seal the cut in the grommet and around all wires. Secure any loose wires with the provided cable ties.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape. The converter should be mounted in a location that is convenient and out of the way, as the 4-flat connector should be rolled up and stored inside the trunk when not in use.
Drilling may be required for the ground wire connection. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, you will need to drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area should be free of rust, dirt and paint.
Yes. You must remove the grommet from which the vehicle taillight wiring harness passes through from inside the trunk to underneath the vehicle, and cut a slit large enough to route the new custom wiring end through. After routing the wires, reseat the grommet and use the provided sealant to seal the cut in the grommet and around all wires.
The battery connection must be fuse-protected with a 10-amp maximum fuse. The manual states: "The battery connection must be fuse-protected, 10-amp max. Exceeding the product rating can cause loss of warranty, overheating and potential fire." The fuse holder with 10-amp fuse is provided and should be installed after all other steps are complete.
Signal circuits are rated at 3.0 amps per side. Tail/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. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
If a suitable existing grounding point is not available, drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
The wiring harness uses the following colours: Red = Brake, Yellow = Left turn, Green = Right turn, Brown = Taillight. The converter also includes a white ground wire and a black power wire. Each wire must be connected to the correct vehicle connector to ensure proper function.
Route the 12-gauge black power wire from the vehicle battery to the converter, taking care to avoid any 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 power wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties. Attach the ring terminal of the power wire to the positive (+) battery terminal. Install the provided fuse holder with 10-amp fuse after all other steps are complete. The negative battery cable must be disconnected before wiring the power wire and reconnected after installation is complete.
Locate a suitable grounding point on the driver side behind the side wall panel near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. Alternatively, attach the ring terminal of the white ground wire to the vehicle body using the screw provided (drill a 3/32" hole if necessary).
Key safety warnings: (1) Do not exceed product rating or tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire. (2) The battery connection must be fuse-protected, 10-amp max. (3) Check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and personal injury. (4) Route the power wire to avoid pinch points and hot or rotating components. (5) Disconnect the negative battery cable before wiring the power wire. (6) Use a ring terminal for battery connection. (7) When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect from sharp edges.
After installation: (1) Reinstall all items removed during installation. (2) Reconnect the negative battery terminal if it was disconnected. (3) Install the provided 4-flat dust cover to help prevent corrosion. (4) Test for proper function by using a test light or connecting a properly wired trailer. (5) Ensure all wires are secured with cable ties and the grommet is sealed with the provided sealant.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the fuse periodically to ensure it has not blown. If the system stops functioning, verify that the fuse is intact and that all connections remain tight and free of corrosion.
The manual states that when in use, the 4-flat should be routed to the center of the vehicle and out of the trunk. When not in use, it should be rolled up and stored in a convenient, out-of-the-way location inside the trunk. A 4-flat dust cover is provided to help prevent corrosion. However, the manual does not specify the exact function or what the 4-flat connector connects to.
