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 Kia K5 (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 Kia K5 (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 21 - 24 Kia K5 Curt 1-1/4", Class 1 Trailer Tow Hitch + 4-flat Wiring Kit 11623 (Part #CHW-2026) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 11623 has a gross trailer weight (GTW) capacity of 2,000 lbs and a tongue weight (TW) capacity of 200 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
Yes. The underbody panel must be removed to access the hitch mounting area. Four push fasteners and two nuts secure it. After removal, the panel is trimmed and reinstalled after the hitch is mounted.
Yes, if your vehicle is equipped with a charcoal canister, it must be removed during installation. The canister is lowered and its hardware returned to the owner. After the hitch is installed, the canister is reinstalled using the supplied M8 hex bolts, flat washers, lock washers, and round hole spacers, with a spacer placed between the frame rail and canister.
The exhaust system must be lowered during installation. Two nuts on the rear-most exhaust bracket and two rubber exhaust hangers are removed to allow the exhaust to be lowered. The exhaust must be supported before removing the hangers. After the hitch is installed, the exhaust is raised back into position and the rubber hangers are reinstalled.
Required tools include: ratchet, sockets (10mm, 12mm, 17mm), socket extension (6"), torque wrench, rotary cutting tool or reciprocating saw, die grinder, flathead screwdriver, aviation shears, exhaust removal pliers, tape measure, marker, and tape. A 5/8" open-end wrench can substitute for exhaust removal pliers if needed.
The kit includes: 4 carriage bolts (7/16"), 4 serrated flange nuts (7/16"), 4 square hole spacers (0.250" × 0.88" × 2.25"), 4 fishwires (7/16"), 2 hex bolts (M8), 2 flat washers (5/16"), 2 lock washers (5/16"), and 2 round hole spacers (0.500" × 1.25" × 2.50").
The manual does not specify whether the battery must be disconnected. Consult your vehicle manufacturer's service manual or contact CURT Product Support at 877-287-8634 for guidance specific to your vehicle.
The manual rates this installation as 'Easy' based on time and effort involved, though difficulty may vary depending on installer expertise, vehicle condition, and availability of proper tools. The installation involves part removal, trimming, hole enlargement, and use of a fishwire technique. If you are not comfortable with these tasks, professional installation is recommended.
Yes. You must support the exhaust before removing the rubber hangers and nuts in Step 2. Failure to support the exhaust can cause damage to the exhaust system.
Yes. The forward-most attachment hole on each frame rail must be enlarged to 1/2" diameter using a grinder. You may also need to enlarge the access hole to allow fishwiring of hardware. The heat shield and underbody panel must be trimmed using the trim diagrams provided in the manual.
According to the trim diagram on page 5, trim the heat shield and underbody panel as follows: 11-1/2" from one reference point, 3" from another, 6" from another, 7" from another, and 4" from another. Refer to the trim diagrams in Step 5 for exact reference points and orientation on your vehicle.
Yes. The hole enlargement to 1/2" diameter and trimming of the heat shield and underbody panel are permanent modifications to your vehicle. These cannot be easily reversed.
All 7/16" hardware (carriage bolts and serrated flange nuts) must be torqued to 59 ft-lbs.
All M8 hardware (hex bolts, flat washers, and lock washers) used to reinstall the charcoal canister must be torqued to 23 ft-lbs.
The forward-most attachment hole on each frame rail must be enlarged to 1/2" diameter using a grinder.
The fishwire is used to guide the 7/16" carriage bolts and square hole spacers through the frame rails via the access holes. The coiled end of the fishwire is inserted through the hitch mounting hole and out the access hole, passed through the spacer, and threaded into the bolt coil. The wire is kinked to keep the spacer separate from the bolt. The fishwire then guides the hardware through the frame and prevents loss of bolts or spacers inside the frame rail.
The fishwire is left attached to the hardware after Step 6. It is removed in Step 7 after the hitch is raised into position and the fishwire is fed through the slots. The hitch is then secured using the serrated flange nuts.
Remove components in this order: (1) underbody panel (four push fasteners and two nuts); (2) charcoal canister if equipped (two bolts); (3) exhaust bracket nuts and rubber hangers (support exhaust first); (4) heat shield (three nuts); (5) rubber plugs and adhesive covers from mounting and access holes.
Reinstall components in this order: (1) trimmed heat shield (after Step 6); (2) trimmed underbody panel; (3) exhaust system and rubber hangers; (4) charcoal canister if equipped, using M8 hex bolts, flat washers, lock washers, and round hole spacers.
Use caution when handling trimmed heat shield and underbody panel—the edges may be sharp. Wear appropriate protective equipment such as gloves to avoid cuts.
Never exceed your vehicle manufacturer's recommended towing capacity. The CURT 11623 has a gross trailer weight capacity of 2,000 lbs and tongue weight capacity of 200 lbs, but your vehicle's manufacturer may specify a lower limit. Always follow the more restrictive specification.
Periodic inspection of the hitch should be performed to ensure all hardware and components remain secure. The manual does not specify the inspection interval or detailed checklist. Contact CURT Product Support at 877-287-8634 or visit curtmfg.com for detailed post-installation inspection guidance.
The manual does not specify a retorque interval. Contact CURT Product Support at 877-287-8634 or visit curtmfg.com for maintenance and retorque recommendations.

The Curt 56469 is a powered converter lead designed to convert a vehicle's taillight signals into a 4-flat trailer connector. It allows you to connect a trailer to a passenger car by tapping into the existing taillight wiring and providing a powered 4-flat connector for the trailer. The converter includes a black converter box that mounts inside the trunk and routes wiring to both taillights.
The Curt 56469 is designed for passenger cars with 12-volt negative ground electrical systems. The manual does not specify which vehicle models or years are compatible. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make and model to confirm compatibility before purchasing.
Yes. The converter system is designed to be used only on 12-volt negative ground systems. If your vehicle has a positive ground system, this product is not compatible.
You will need: flathead screwdriver, cutting tool, panel trim removal tool, wire crimper, electrical tape, and wire stripper. A 3/32" drill bit may also be required if you need to drill a pilot hole for the ground wire fastening.
The kit includes: a black converter box, double-sided tape for mounting, a white ground wire with ring terminal, a black power wire, a green wire, a yellow wire, cable ties, a 4-flat dust cover, a ground screw, and a fuse holder with 15-amp fuse. The fuse should be installed only after all other installation steps are complete.
Yes. You must disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery while completing the installation process. Reconnect the negative battery terminal only after all other steps are complete and you have tested the harness with a test light, 4-flat tester, or functioning trailer.
Open the trunk and remove the floor covering to expose the spare tire. Using a large flathead screwdriver, remove the two fasteners in the threshold (one on each side). Using a panel trim removal tool, loosen the push fasteners in the trunk threshold, then lift and slide off the threaded bolt. This provides access to the taillight connectors and space for the converter box.
Pull back the sidewall panels inside the trunk. Using a panel trim removal tool, loosen the push fasteners in the side wall (two per side) and pull back the felt liner to expose the taillight electrical harness. Repeat on the passenger side as needed.
Locate a flat spot on the driver side of the vehicle behind the felt trunk liner. Adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and dry before applying the tape.
Starting on the driver side, pull back the sidewall panels and locate the taillight housing. Separate the connectors carefully, taking care not to damage the locking tabs. Install the custom wiring harness end with the yellow wire positioned between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Route the green wire along the back of the trunk below the threshold to the passenger side of the vehicle. Zip tie in place as needed. Locate the taillight housing and separate the connectors, taking care not to damage the locking tabs. Install the housing with the green wire positioned between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
Not necessarily. Locate a grounding point such as an existing screw or bolt in the frame of the vehicle. If no suitable existing fastener is available, you may drill a 3/32" pilot hole. 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 from rust, dirt, and paint—use an abrasive pad or paper to remove rust and paint if needed.
Drill a 3/32" pilot hole if an existing screw or bolt is not available for grounding. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The converter uses the following wire colors: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight (running lights). The black power wire connects to the positive battery terminal, and the white ground wire connects to the vehicle frame or body.
Route the black 12-gauge power wire from the converter to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components. Use the ring terminal provided to connect the black power wire to the positive (+) battery terminal. 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. Secure the power wire to the vehicle chassis using the provided cable ties.
Attach the ring terminal of the white ground wire to the vehicle body using the provided screw. If no suitable existing fastener is available, drill a 3/32" pilot hole. The area should be free from rust, dirt, and paint—use an abrasive pad or paper to remove rust and paint before securing the ground wire.
The battery connection must be fuse-protected with a 15-amp maximum fuse. The kit includes a fuse holder with a 15-amp fuse. Install the fuse only after all other installation steps are complete. Exceeding the 15-amp rating can cause loss of warranty, overheating, and potential fire.
Signal circuits (left and right turn): 5.0 amps per side. Tail/Running circuits: 7.5 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.
Disconnect the negative battery terminal before beginning installation and fasten it down and away from the battery. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. When routing the power wire, avoid pinch points and hot or rotating components. Use a ring terminal for the battery connection. Do not install the fuse until all other steps are complete. Wear appropriate protective equipment when using tools and handling electrical components.
When in use, route the 4-flat connector with the center of the vehicle and out of the hatch to the trailer. Be sure to stay clear of the hatch's latching mechanism. When not in use, roll up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties.
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. Do not reconnect the negative battery terminal until you have completed this test. After testing, reinstall all items removed during installation and reconnect the negative battery terminal if it was disconnected.
After testing the harness with a test light, 4-flat tester, or functioning trailer, reinstall all items removed during installation. Reconnect the negative battery terminal if it was disconnected at the beginning. Install the provided 4-flat dust cover to help prevent corrosion. Secure any loose wires with the provided cable ties.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the 4-flat connector and dust cover regularly, especially if the trailer is used frequently. Keep the connector clean and store it in a convenient, out-of-the-way location when not in use.
