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 Golf and GTI (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 Golf GTI (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.

Two people may be required to ease installation, though the manual does not state this is mandatory. If you are hesitant to undertake the task on your own, contact an authorized CURT installer for assistance.
Yes. Step 1 requires you to temporarily lower the exhaust by removing the M8 bolts from the two rear exhaust hangers using a 13mm socket. Save these bolts for reinstallation in Step 5 after the hitch is secured.
Fishwire is a temporary installation aid included in the kit (4× 1/2" fishwire). In Step 2, you thread the 1/2" carriage bolts and SP10 spacers through the access holes in the driver and passenger side frame rails using the fishwire. In Step 3, you reverse the fishwire bolts and spacers into position, leaving the fishwires attached. In Step 4, you remove the fishwires after raising the hitch into position.
All 1/2" hardware (carriage bolts and flange nuts) must be torqued to 110 ft-lbs. This is done in Step 5 after the hitch is raised into position and loosely secured.
All non-trailer loads (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 www.curtmfg.com for further information on stabilizing straps.
Never exceed your vehicle manufacturer's recommended towing capacity. Although CURT 11412 is rated for 2,000 lbs trailer weight and 200 lbs tongue weight, your vehicle's manufacturer may specify a lower limit. Always follow the vehicle manufacturer's guidance.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify an interval, but recommends this as an ongoing maintenance practice.

The CURT 56405 is a powered converter lead wiring harness designed to integrate trailer lighting with passenger car electrical systems. It converts the vehicle's taillight signals (left turn, right turn, brake, and running lights) into a format compatible with a trailer connector. The system includes a converter box, custom wiring harness with colour-coded wires, and a battery power lead.
The CURT 56405 is designed for passenger cars with 12-volt negative ground electrical systems. The manual does not list specific vehicle makes, models, or years. Consult your vehicle owner's manual to confirm your vehicle has a 12-volt negative ground system, or contact CURT directly to verify fitment for your specific vehicle.
No. The CURT 56405 is designed only for 12-volt negative ground systems. Do not attempt to install it on a positive ground vehicle, as this will cause improper operation and potential damage.
You will need: ratchet, utility knife, Torx bit T-20, wire crimper, Torx bit T-27, socket extension, wire stripper, and panel trim removal tool. A 3/32" drill bit is also required if you need to drill a pilot hole for the ground wire screw.
The kit includes a custom wiring harness with colour-coded wires (yellow for left turn, green for right turn, white for ground, red for brake, brown for taillight), a black converter box, a black power wire, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for mounting the converter box, cable ties for securing wires, a fuse holder with 15-amp max fuse, and a 4-flat dust cover.
Yes. Step 1 requires you to locate the vehicle battery, disconnect the negative battery terminal, and fasten this wire down and away from the battery. The negative battery must remain disconnected until you reconnect it at the end of the installation after all other steps are complete.
Open the trunk and remove all trunk floor coverings. Remove the fasteners securing the rear scuff panel and remove the scuff panel by pulling out on the bottom and then up, taking care not to damage the alignment tabs on the back.
Starting on the driver side, remove the fasteners from the interior side trim panel and pull outward to locate the push fasteners behind the panel. Remove the push fasteners from the side felt liner and pull back the felt liner to locate the vehicle taillight wiring harness connectors. Separate the connectors 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, ensuring the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the harness end with the green wire.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole. The area must be free of rust, dirt, and paint. Secure the white ground wire using the ring terminal and the provided screw.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and dry before applying the tape.
Route the black power wire from the vehicle battery as shown on the last page of the manual (page 4). Route the 12 GA wire to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components. When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Drilling may be required for the ground wire connection. If a suitable existing screw with nut is not available in the vehicle frame near the taillight connector, you must drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
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 of rust, dirt, and paint. Drill a 3/32" pilot hole only if no suitable existing screw with nut is available in the vehicle frame.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone to protect the power wire from sharp edges. This prevents damage to the wire insulation and potential electrical hazards.
The signal circuits (left turn and right turn) are rated for 5.0 amps per side.
The tail and running light circuits are rated for 7.5 amps total.
The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed this rating. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
The power wire must be 12 GA (12 gauge) or larger.
The pilot hole for the ground wire screw is 3/32" diameter. Drill this hole only if a suitable existing screw with nut is not available in the vehicle frame.
Yellow wire = left turn signal; Green wire = right turn signal; Red wire = brake signal; Brown wire = taillight/running lights; White wire = ground. These colours correspond to the vehicle's taillight signals and must be connected to the appropriate taillight connectors.
Route the black 12 GA power wire to the vehicle battery positive (+) terminal using a ring terminal connector. The battery connection must be fuse-protected with a 15-amp maximum fuse. Install the fuse after all other installation steps are complete. Disconnect the negative battery terminal before wiring the power wire, and route the wire to avoid pinch points and hot or rotating components.
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 the 4-flat to the center of the vehicle and out of the trunk.
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. Check your vehicle owner's manual or contact the vehicle manufacturer for the specific lamp load rating of your vehicle.
Route the 12 GA power wire to the vehicle battery location, 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 new grommet, or use silicone to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This is especially important when drilling the 3/32" pilot hole for the ground wire screw.
Reinstall all items removed during installation, including trunk floor coverings, scuff panel, and side trim panels. Reconnect the negative battery terminal if it was disconnected at the beginning. Install the provided 4-flat dust cover to help prevent corrosion. Test the system for proper function by using a test light or connecting a properly wired trailer.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. This ensures all signal circuits (left turn, right turn, brake, and running lights) are functioning correctly.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. This helps maintain proper electrical function and prevents potential safety hazards.
The provided 4-flat dust cover helps prevent corrosion of the connector when it is not in use. Install it after completing the installation.
