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 Passat (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 R (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 56374 is designed for passenger cars with 12-volt negative ground electrical systems. The wiring harness connects at locations P3 and P4 (behind driver and passenger side taillight housings, inside of trunk). Check your vehicle owner's manual to confirm it has a 12-volt negative ground system. If your vehicle does not have this electrical configuration, this product will not function properly.
The product has the following electrical ratings: Signal circuits (turn signals) 5.0 amps per side; Tail/Running circuits 7.5 amps total. The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
Required tools are: ratchet, ratchet extension, socket (10mm), flathead screwdriver, Phillips screwdriver, Torx bit (T-30), wire crimper, wire stripper, panel trim removal tool, and cutting tool. Proper tools will improve the quality of installation and reduce the time required.
Yes. You must disconnect the negative battery terminal before beginning installation. Locate the battery in your vehicle owner's manual, disconnect the negative terminal, and fasten this wire down and away from the battery. Reconnect the negative battery terminal only after all other installation steps are complete and the fuse has been installed.
Remove the following: all trunk floor coverings and storage trays, the scuff panel (by pulling out at the bottom then up, taking care not to damage alignment tabs), and the interior side trim panels on both driver and passenger sides. These panels must be removed to access the taillight wiring harness connectors located behind them.
1. Behind the removed trim panel, locate the vehicle taillight wiring harness connectors. 2. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. 3. Insert the custom wiring harness end with the yellow wire between the separated connectors. 4. Make sure the connectors are fully inserted with locking tabs in place. 5. Repeat this process on the passenger side using the harness end with the green wire.
You may need to drill a 3/32" pilot hole if a suitable grounding point is not available. Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing point is available, drill a 3/32" pilot hole. The area must be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The pilot hole for the ground wire screw is 3/32". This hole is drilled only if a suitable existing grounding point (such as an existing screw with nut in the vehicle frame) is not available. The area must be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
The wiring harness includes the following colors: Green (right turn signal), Red (brake), Yellow (left turn signal), Brown (taillight), and White (ground). The custom wiring harness has two ends: one with a yellow wire (driver side) and one with a green wire (passenger side). The black power wire connects to the vehicle battery positive terminal, and the white ground wire connects to the vehicle body.
The power wire is 12 gauge (12 GA) or larger. This wire routes from the vehicle battery to the converter system and must be secured to the vehicle chassis using the provided cable ties. 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.
The battery connection must be fuse-protected with a 15-amp maximum fuse. Install the fuse after all other installation steps are complete. Exceeding the 15-amp rating can cause loss of warranty, overheating and potential fire. The fuse holder is provided with the product.
Adhere the black converter box using the provided double-sided tape. Locate a flat spot inside the vehicle near the taillight. The converter box should be mounted in a location where it will not interfere with vehicle operation or be damaged by moving items in the trunk.
When in use, route the 4-flat 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 to prevent tangling and damage.
1. Reinstall all items removed during installation (trim panels, scuff panel, floor coverings and storage trays). 2. Reconnect the negative battery terminal if it was disconnected at the beginning. 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.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. The product has signal circuit ratings of 5.0 amps per side and tail/running circuit ratings of 7.5 amps total. For specific towing capacity information, check your vehicle owner's manual or contact the vehicle manufacturer.
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 before towing. Ensure all cable ties remain secure and that wires have not shifted or become pinched.
No. The CURT 56374 is designed for use only on 12-volt negative ground systems. If your vehicle has a 24-volt system or positive ground electrical system, this product will not function and should not be installed. Check your vehicle owner's manual to confirm your electrical system configuration.
Route the 12 GA power wire to the vehicle battery location taking care to avoid any pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties. 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. Before routing, check for miscellaneous items that may be behind or under any surface to avoid damage and personal injury.
The CURT 56374 is designed for passenger cars with 12-volt negative ground electrical systems. Verify your vehicle has this electrical configuration in your owner's manual. The wiring connects at taillight locations P3 and P4 (inside trunk, behind taillight housings).
You will need: ratchet, ratchet extension, 10mm socket, flathead and Phillips screwdrivers, T-30 Torx bit, wire crimper, wire stripper, panel trim removal tool, and cutting tool.
Yes, disconnect the negative battery terminal before starting installation. Fasten the wire down and away from the battery. Reconnect only after all other steps are complete and the fuse is installed.
Drilling may be required only for the ground wire. If no existing grounding point is available on the vehicle frame, drill a 3/32" pilot hole. Check for hidden items before drilling to avoid damage.
The battery connection must use a 15-amp maximum fuse. Install the fuse after all other steps are complete. Exceeding 15 amps can cause warranty loss, overheating and fire.
Signal circuits: 5.0 amps per side. Tail/Running circuits: 7.5 amps total. Do not exceed the product rating or your vehicle's lamp load rating, whichever is lower.
Periodically inspect all wires and connections for visible damage or loose connections. Check the 4-flat connector and dust cover before each towing use.
Ensure the connectors are aligned correctly and being inserted straight. The connectors should be fully inserted with locking tabs in place. If resistance is felt, do not force the connection as this may damage the locking tabs. Check that you are using the correct harness end (yellow wire for driver side, green wire for passenger side) and that the vehicle taillight connectors have been properly separated from the taillight housing.
Perform these checks: (1) Verify the negative battery terminal is reconnected. (2) Confirm the 15-amp fuse is installed in the fuse holder. (3) Check that all wiring connectors are fully inserted with locking tabs in place. (4) Inspect all wires and connections for visible damage or loose connections. (5) Verify the ground wire ring terminal is securely attached to the vehicle body. (6) Test for proper function using a test light or by connecting a properly wired trailer. If the product still does not function, there may be a wiring connection issue or the vehicle may not have a 12-volt negative ground system.
