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 Volkswagen Jetta (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 Volkswagen Jetta (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 Curt 56555 is a T-connector wiring converter that integrates trailer lighting signals into a vehicle's factory taillight wiring. It allows you to connect a 4-flat trailer connector to your vehicle's electrical system by tapping into the existing taillight harness. The converter processes left turn, right turn, brake, and taillight signals from the vehicle and routes them to the trailer connector.
The Curt 56555 is designed for passenger cars with rear taillights accessible from the trunk. It is compatible only with 12-volt negative ground electrical systems. The manual does not specify which vehicle makes and model years are supported. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle before purchasing.
No. The Curt 56555 is designed only for 12-volt negative ground systems. It cannot be used on 24-volt systems or positive ground systems.
You will need: ratchet, Phillips screwdriver, ratchet extension, wire cutter, 10mm socket, wire stripper, drill, 3/32 drill bit, T-25 Torx bit, test light, crimp tool, and trim panel tool. The manual rates installation difficulty as 'Difficult', so proper tools are essential to complete the work correctly.
The kit includes: T-connector housing with yellow, green, brown, and red wires; custom wiring ends; white ground wire with ring terminal; black power wire; 4-flat connector with dust cover; double-sided tape for mounting the converter module; cable ties for securing loose wires; ground screw; silicone sealant; and a 15-amp fuse holder with fuse. You must supply 12 GA wire or larger to route from the vehicle battery to the converter.
Yes. You must disconnect and isolate the negative battery terminal before beginning installation. Use a 10mm socket or wrench to disconnect it. Ensure the negative cable does not touch any metal object, as this could cause damage to the vehicle's electrical system. Reconnect the battery only after all wiring is complete (Step 15).
The installation is rated as 'Difficult'. The difficulty level is based on time and effort involved and may vary depending on installer expertise, vehicle condition, and availability of proper tools and equipment. The installation involves removing taillights, routing wires through grommets, drilling holes, and making electrical connections.
Open the trunk and locate the taillight trim panels covering the mounting bolts. Remove the covers. Remove the two bolts on each side holding the taillights in place using a T-25 Torx bit. Pull the taillight backwards from the side of the vehicle. Separate the connector from the taillight housing carefully to avoid damaging the locking tabs. Repeat on the other side. The taillight connectors provide access to the factory taillight wiring harness.
Two grommets must be modified to route the converter wiring. The first grommet, located between the taillight pocket and trunk, must be unseated and slit with a utility knife to allow the module connector's wiring (brown and red wires) to pass through. The second grommet, behind the taillight where factory taillight wiring passes from the cabin to the taillight, must be removed and slit to route the custom wiring end through. Both grommets are then reseated and sealed with silicone sealant to prevent water intrusion.
The T-connector housing contains the yellow wire (left turn signal). Route it up through the grommet hole following the taillight wire harness. Ensure the yellow wire is seated into the slit of the grommet. The T-connector is inserted between the separated taillight connector and the factory taillight wiring harness, with locking tabs fully inserted. Repeat the same process on the passenger side using the green wire (right turn signal). The brown and red wires (taillight and brake) are routed separately through the first grommet.
Mount the lighting module in a suitable location using the provided double-sided tape, with the epoxy side down. The location should be out of the way, such as inside the cargo area or behind a panel. The module must be positioned so that wires are not pinched or damaged when reassembling trim panels and taillights.
Locate a suitable grounding point such as an existing screw or bolt on the vehicle frame. If no suitable point exists, drill a 3/32 inch pilot hole. The area must be free from rust, dirt, and paint—use an abrasive pad or paper to clean it. Secure the white ground wire with its ring terminal to the existing fastener or with the provided ground screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Route 12 GA wire or larger from the vehicle battery location to the converter, taking care to avoid pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone sealant to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties. Refer to the 'Powered Converter Lead Instruction Sheet' on page 6 for detailed routing guidance.
Route the 4-flat connector to the center of the cargo area. When not in use, store it in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent tangling and damage.
Signal circuits (left and right turn): 5.0 amps per side. Tail/Running circuits: 7.5 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
The battery connection must be fuse-protected with a maximum 15-amp fuse. The kit includes a 15-amp fuse holder. Install the fuse after all other installation steps are complete. Do not exceed 15 amps, as this can cause loss of warranty, overheating, and potential fire.
Use a 3/32 inch drill bit to create a pilot hole for the ground wire attachment point if an existing screw or bolt is not available. The area must be cleaned of rust, dirt, and paint before drilling.
Yellow = Left turn signal; Green = Right turn signal; Red = Brake signal; Brown = Taillight/Running light. The white wire is the ground wire, and the black wire is the power wire that connects to the vehicle battery positive terminal.
Use 12 GA wire or larger to route from the vehicle battery to the converter. This wire size is required to safely handle the 15-amp maximum fuse rating and prevent voltage drop.
Do not lay tools across the positive battery terminal (typically marked with red covers or a red '+' symbol), as this can cause a ground short leading to sparks and electrical shocks. Always disconnect and isolate the negative battery terminal before beginning installation. Ensure the negative cable does not touch any metal object. Use a ring terminal for the battery connection. Install the 15-amp fuse only after all other steps are complete.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area where you drill must be free from rust, dirt, and paint. Use an abrasive pad or paper to clean the area. Avoid drilling near fuel lines, brake lines, wiring harnesses, or other critical components.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or apply silicone sealant to protect the wire from sharp edges. This prevents the wire insulation from being cut or abraded, which could cause electrical shorts or fire.
After installation is complete, verify that the harness is functioning by attaching the 4-flat connector to any trailer with functioning lights, or use one of the following: 4-flat tester, test light, or multimeter. Test all four signals: left turn, right turn, brake, and running lights. Ensure all connections are secure and no wires are pinched or damaged.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Check that the double-sided tape mounting the converter module remains secure. Inspect the silicone sealant around the grommet slits to ensure it has not deteriorated. Verify that cable ties are still secure and wires are not rubbing against sharp edges or moving components.
Yes. Install the provided 4-flat dust cover to help prevent corrosion of the connector pins. This should be done after the battery is reconnected and before the vehicle is used with a trailer.
The Curt 56555 is designed for passenger cars with rear taillights accessible from the trunk and 12-volt negative ground systems. Consult a fitment database or contact Curt Manufacturing to confirm compatibility with your specific vehicle make and model year.
Yes. Disconnect and isolate the negative battery terminal using a 10mm socket before beginning installation. Reconnect it only after all wiring is complete.
Drilling may be required. You must locate a grounding point on the vehicle frame; if no existing screw or bolt is available, drill a 3/32 inch pilot hole. The area must be cleaned of rust, dirt, and paint. Check for hidden items before drilling to avoid damage.
The battery connection must use a 15-amp maximum fuse. The kit includes a 15-amp fuse holder. Install the fuse after all other steps are complete.
Use 12 GA wire or larger to route from the vehicle battery to the converter.
Do not lay tools across the positive battery terminal, as this can cause a short circuit, sparks, and electrical shock. The battery connection must be fuse-protected with a 15-amp maximum fuse. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Verify that the harness is functioning by testing with a 4-flat tester, test light, or multimeter. Check that all wire connections are fully inserted with locking tabs in place. Ensure the T-connector housings (yellow and green wires) are properly seated between the factory taillight harness and the taillight connectors. Verify that the brown and red wires are fully inserted between the separated connectors. Confirm that the 15-amp fuse is installed and not blown. Check that the white ground wire is securely attached to the vehicle frame grounding point.
Disconnect the battery immediately. Inspect the damaged wire and determine if it can be safely repaired or must be replaced. If the wire insulation is cut or abraded, it must be repaired with electrical tape or a butt connector and heat shrink tubing to prevent shorts. Ensure all wires are routed away from moving parts, sharp edges, and pinch points before reassembling trim panels and taillights. Retest the converter before reconnecting the battery.
Water intrusion is likely caused by unsealed grommet slits. Disconnect the battery and inspect the grommets where wires pass through. Apply silicone sealant to any slits that are not sealed, particularly around the first grommet (between taillight pocket and trunk) where the brown and red wires pass through. Ensure the grommet is fully reseated in the body opening. Allow the sealant to cure according to the manufacturer's instructions before reconnecting the battery.
