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 Chevy Cruze (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 Chevy Cruze (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 56319 Custom Wiring Harness is designed for Chevrolet Cruze (LS, LT & Premier) passenger cars. Verify your vehicle matches these trim levels and body style before purchasing.
The Curt 56319 has a Signal Circuits rating of 7.5 amps per side and Tail/Running Circuits rating of 7.5 amps total. Do not exceed these ratings or your tow vehicle's lamp load rating, whichever is lower, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this specification can cause loss of warranty, overheating and potential fire.
You will need: 10mm socket, 7mm socket, ratchet, panel trim removal tool, wire stripper, wire crimper, and cutting tool.
Yes. Step 1 requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before beginning installation.
The custom wiring harness end with the green wire is inserted between the separated connectors at the passenger side taillight housing. Make sure the connectors are fully inserted with locking tabs in place.
The custom wiring harness end with the yellow wire is routed to the driver side behind the removed scuff panel and inserted between the separated connectors at the driver side taillight housing, following the same procedure as the green wire on the passenger side.
Drilling may be required for the ground wire. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you will need to drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
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.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When in use, route the 4-flat to the center of the vehicle. 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.
Reinstall all items removed during installation, reconnect the negative battery terminal, and install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
When separating the vehicle taillight wiring harness connectors, take care not to damage the locking tabs. When inserting the custom wiring harness connectors, make sure they are fully inserted with locking tabs in place.
Open the vehicle trunk and remove all trunk floor coverings. Remove the scuff panel by pulling out on the bottom and then up, taking care not to damage the alignment tabs on the back. Remove the push fasteners from the side felt liner to access the taillight wiring harness connectors.
