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 Elantra (excluding N and N Line; 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 Elantra (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.

Part 56470 is a custom wiring harness with powered converter system designed for passenger cars. It provides electrical connections for trailer lighting by interfacing with the vehicle's taillight wiring and includes a converter box that processes the vehicle's taillight signals. The system includes a 4-flat connector for trailer attachment.
The 56470 is designed for passenger cars with accessible taillight wiring. The manual specifies it is for 12-volt negative ground systems only. Specific vehicle makes, model years and body styles are not listed in the manual. Contact the manufacturer or check the product listing for your specific vehicle compatibility.
No. The manual explicitly states 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.
You will need: panel trim removal tool, wire crimper, cutting tool, wire stripper, pliers, and electrical tape. The manual notes that proper tools will improve installation quality and reduce time required.
The kit includes: a black converter box, custom wiring harness with yellow, green, black, white, red and brown wires, a 4-flat connector with dust cover, double-sided tape for mounting the converter box, cable ties for securing wires, a ring terminal for the ground wire, a fuse holder with 10-amp fuse, and a screw for the ground wire attachment. A separate 'Powered Converter Lead Instruction Sheet' is also provided.
Yes. Step 1 requires you to locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation. The battery must remain disconnected until after all wiring is complete and tested.
You must remove: floor coverings, two cargo hooks on each side of the threshold, the threshold itself (by removing the push fastener under the trunk latch), the threaded cargo net mount from the post, and two small push fasteners in both sidewalls to pull out the trunk liner. Use the panel trim removal tool to release push fasteners. You may also need to use the tool to release push fasteners on the underside of the skid plate.
In Step 4, pull back the sidewall panels to locate the vehicle's taillight wiring connectors on the driver side. Separate the connectors from the taillight housing carefully, taking care not to damage the locking tabs. Insert the custom wiring end with the yellow wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
In Step 5, locate a flat spot inside the vehicle on the driver side and adhere the black converter box using the provided double-sided tape. The manual does not specify exact dimensions or clearance requirements for this location.
In Step 6, route the green wire along the back of the trunk below the skid plate to the passenger side of the vehicle. Locate the taillight housing and separate the connectors, taking care not to damage the locking tabs. Install the housing with the green wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
In Step 7, route the black power wire from the vehicle battery as shown on the provided 'Powered Converter Lead Instruction Sheet'. The power wire must be 12 gauge or larger, routed to avoid pinch points and hot or rotating components. Use a ring terminal for the battery connection. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect it 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 screw provided. If necessary, drill a 3/32" hole to mount the ground wire. This connection is shown on the 'Powered Converter Lead Instruction Sheet'.
Drilling may be required only for the ground wire connection. You may need to drill a 3/32" hole to attach the white ground wire's ring terminal to the vehicle body. Before drilling, check for miscellaneous items that may be behind or under any surface to avoid personal injury or property damage. No other drilling is mentioned as required for the installation.
Signal circuits are rated at 3.0 amps per side. Tail and 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 the tow vehicle lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
A 10-amp maximum fuse is required. The fuse holder is included in the kit. Install the fuse after all other installation steps are complete, not before.
The power wire must be 12 gauge or larger. This is specified on the 'Powered Converter Lead Instruction Sheet'.
If necessary, drill a 3/32" hole to attach the white ground wire's ring terminal to the vehicle body using the provided screw.
The wire colors and their functions are: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight (running light), White = Ground, Black = Power (positive battery connection).
The manual provides these wiring locations for passenger cars: P1 = Behind driver side taillight housing, outside of trunk; P2 = Behind passenger side taillight housing, outside of trunk; P3 = Behind driver side taillight housing, inside of trunk; P4 = Behind passenger side taillight housing, inside of trunk; P5 = Behind driver side rear bumper; P6 = Behind center of rear bumper; P7 = Behind passenger side rear bumper. The specific location on your vehicle may vary.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route the 4-flat to the center of the vehicle and out of the trunk to the trailer, being sure to stay clear of the trunk's latching mechanism.
The manual does not specify a towing load rating. It states only that you must not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Refer to the vehicle owner's manual or contact the vehicle manufacturer for towing capacity information.
After connecting the 12-volt power wire 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. The manual notes that once installed, you should test for proper function before considering the installation complete.
Reinstall all items that were removed during installation, including the floor coverings, cargo hooks, threshold, cargo net mount, sidewall panels, and trunk liner. After reinstalling everything, reconnect the negative battery terminal if it was disconnected at the beginning of the installation. Install the provided 4-flat dust cover to help prevent corrosion.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval. Secure any loose wires with the provided cable ties, and keep the 4-flat dust cover installed when the connector is not in use to help prevent corrosion.
The 56470 is designed for passenger cars with 12-volt negative ground electrical systems. Specific vehicle makes and model years are not listed in the manual. Check the product listing or contact the manufacturer to confirm compatibility with your vehicle.
You will need: panel trim removal tool, wire crimper, cutting tool, wire stripper, pliers, and electrical tape. All other required components are included in the kit.
Yes, you must disconnect the negative battery terminal before beginning installation and keep it disconnected until after all wiring is complete and tested.
A 10-amp maximum fuse is required. Install the fuse after all other installation steps are complete.
After connecting the power wire and battery, verify the harness is functioning by testing with a test light, 4-flat tester, or a functioning trailer before considering installation complete.
The CURT 11687 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.
Required tools include: ratchet, torque wrench, sockets (8mm, 10mm, 12mm, 13mm, 15mm, 11/16"), utility knife, masking tape, fishwire (7/16", 2 qty. included), center punch, aviation shears, exhaust isolator removal tool, Phillips screwdriver, flathead screwdriver, panel trim removal tool, tape measure, paint marker, drill, drill bit (1/2"), and safety glasses. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
The CURT 11687 is rated as moderate difficulty. Installation requires lowering the exhaust, removing body panels, taillights and bumper cover, trimming panels, and drilling. Proper tools and mechanical experience are necessary. Difficulty may vary based on installer expertise and vehicle condition.
The manual does not specify which vehicle makes, models, or years are compatible with part number 11687. Contact CURT product support at 877.287.8634 or visit curtmfg.com to confirm fitment for your specific vehicle before purchasing.
The kit includes: 1 trailer hitch, 2 pieces of 7/16" fishwire, 2 flange nuts (7/16"-14), 4 round-hole spacers (1/4" x 1" x 1-1/2"), 4 hex bolts (M10–1.25 x 35mm, Class 10.9), 4 conical-toothed washers (7/16"), 2 carriage bolts (7/16"-14 x 1-3/4", grade 8), 4 conical-toothed washers (3/8"), 4 hex bolts (M8–1.25 x 40mm, Class 10.9), and 2 spacers (1/4" x 7/8" x 2-1/4").
Installation requires removal of: driver-side underbody panel (5 push pins and 1 plastic nut), passenger-side underbody panel (4 push pins, 1 plastic nut, and 2 additional nuts), both taillights with wiring harnesses, bumper cover (multiple fasteners and clips), and lowering of the exhaust system onto jack stands. All components are reinstalled after hitch mounting.
The manual does not specify whether battery disconnection is required. Contact CURT product support at 877.287.8634 for guidance on electrical safety precautions before beginning installation.
Yes. A 1/2" diameter hole must be drilled in the driver-side frame rail at the forward mounting location of the hitch side mounting strap. The hitch is raised into position, the hole location is marked, then the hitch is lowered and the hole is drilled.
The bumper cover requires a 5" x 3-3/4" rectangular cutout from the bottom edge. The central underbody panel requires a 5" x 1" rectangular cutout from the rear edge. Both are trimmed with aviation shears or suitable tool. Additional trimming of the driver-side underbody panel may be needed near the forwardmost attachment tab for proper fit.
Yes. The manual requires trimming a 5" x 3-3/4" section from the bottom of the bumper cover and a 5" x 1" section from the central underbody panel using aviation shears. These are permanent modifications to fit the hitch. The trimmed bumper cover is reinstalled after hitch mounting.
For the bumper cover: find the center of the bottom edge, mark points 2-1/2" to either side of center (5" total span), then draw a rectangle from the 5" base up 3-3/4" from the lower edge. For the underbody panel: mark the center, mark points 2-1/2" to either side (5" total span), then mark a rectangle 1" from the rear edge toward the front. Use a paint marker for visibility.
Fishwire is used to guide carriage bolts and spacers through internal frame rail passages where direct access is not possible. The coiled end of the fishwire is inserted through the mounting hole, passed through the spacer, and threaded into the bolt coil. The fishwire then pulls the bolt and spacer through the frame and out the mounting hole, preventing loss of hardware inside the frame rail.
The manual provides two methods. Method 1: Use exhaust hanger removal pliers if available. Method 2: Use a 5/8" open-end wrench slid up to the rubber isolator to cradle the hanger rod, place a pry bar between the wrench and the hanger stop, then rotate the pry bar toward the wrench to remove the isolator. Using lubricant or soapy water on the hanger rod and isolator helps removal.
Driver side first: remove 5 push pins with a flathead screwdriver, then remove 1 plastic nut with a 15mm socket. Passenger side: remove 4 push pins, then remove 1 plastic nut with a 15mm socket and 2 additional nuts with a 12mm socket. Set all fasteners aside for reinstallation.
Open the trunk and remove the taillight access panel on the driver side. Using a 10mm socket, remove 2 nuts inside the panel opening. Unclip the taillight wiring harness carefully without damaging the locking tabs. Slide the taillight rearward out of the vehicle. Repeat on the passenger side. In the rear wheel well, remove 3 screws (Phillips) and 1 bolt (8mm socket), plus 1 screw and 1 push pin in the taillight area.
Remove 2 bumper bolts from each side (4 total) using either an 8mm socket (Korean-made models) or 10mm socket (US-made models) on the forward part of the rear flange. Remove 3 push pins from the lower edge near the wheel well (2 passenger side, 1 driver side). Gently pull the bumper cover away starting at the top edge by the wheel well, working around the top edge. A panel trim removal tool may ease removal of clips.
The conical-toothed washers must be oriented with the teeth pointing toward the hitch side plate and the flat side facing outward. The diagram on page 2 shows the correct orientation: teeth engage the hitch side plate to prevent loosening.
Raise the hitch into position and mark the forward mounting hole on the driver-side mounting strap. Lower the hitch and drill the 1/2" hole. Then raise the hitch again into position, thread the fishwire through the side mounting straps, and secure with the appropriate bolts and washers depending on vehicle origin (M10 or M8 bolts with corresponding washers).
The choice depends on vehicle origin. US-made vehicles use M10 bolts (M10–1.25 x 35mm, Class 10.9) with 7/16" conical-toothed washers. Korean-made vehicles use M8 bolts (M8–1.25 x 40mm, Class 10.9) with 3/8" conical-toothed washers. The manual does not specify how to determine vehicle origin; contact CURT at 877.287.8634 if uncertain.
Torque all 7/16" fasteners to 70 lb-ft, all 8mm fasteners to 23 ft-lb, and all 10mm fasteners to 48 lb-ft. Use a torque wrench to ensure proper tightness and prevent damage to the product or vehicle.
All 7/16" fasteners, including the flange nuts and carriage bolts, must be torqued to 70 lb-ft.
All 8mm fasteners must be torqued to 23 ft-lb.
All 10mm fasteners must be torqued to 48 lb-ft.
The kit includes 2 carriage bolts, 7/16"-14 x 1-3/4", grade 8. These are secured with 7/16" flange nuts and must be torqued to 70 lb-ft.
The kit includes two types of hex bolts: 4 pieces of M10–1.25 x 35mm, Class 10.9 (torque to 48 lb-ft) and 4 pieces of M8–1.25 x 40mm, Class 10.9 (torque to 23 ft-lb). Which type is used depends on vehicle origin (US-made or Korean-made).
A 1/2" diameter hole must be drilled in the driver-side frame rail at the forward mounting location of the hitch side mounting strap.
Before final torquing, temporarily reinstall the bumper cover and check the fit of the cut-out areas. Raise the hitch into position and verify clearance around the hitch, enlarging cut-outs as needed. Check for proper fit around the driver-side underbody panel and trim near the forwardmost attachment tab if needed. After installation, perform periodic inspection to ensure all mounting hardware remains tight and structural components are secure.
The manual states that periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. Specific intervals are not provided; contact CURT product support at 877.287.8634 for recommended inspection schedules.
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.
Safety glasses must be worn at all times during installation. Never exceed your vehicle manufacturer's recommended towing capacity. The exhaust must be supported on jack stands or other suitable supports while lowered to prevent damage to the vehicle. Proper tools will improve installation quality and reduce time required.
Never exceed your vehicle manufacturer's recommended towing capacity. The CURT 11687 is rated for a gross trailer weight of 2,000 lbs and tongue weight of 200 lbs, but your vehicle's capacity may be lower. Consult your vehicle's owner manual for the maximum towing capacity.
