All Hardware and Installation Instructions Included!
Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Buick LaCrosse, Buick Regal, Cadillac XTS, Chevy Impala, Chevy Malibu and Chevy Malibu Limited (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
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 Impala (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 manual does not explicitly state whether the battery must be disconnected before installation. Refer to your vehicle owner's manual or contact the vehicle manufacturer for guidance on safe electrical work procedures.
The custom wiring harness connects to the existing taillight wiring connectors located behind the driver and passenger side taillight housings inside the trunk. The harness end with the yellow wire connects on the driver side (P3), and the harness end with the green wire connects on the passenger side (P4). The connectors insert between the separated factory taillight connectors.
1. Open the trunk and remove all floor coverings. 2. Remove the scuff panel carefully. 3. Remove plastic fasteners securing the felt trunk liner on both sides. 4. On the driver side, separate the factory taillight connectors and insert the harness end with the yellow wire between them. 5. Secure the white ground wire to a clean grounding point using the provided screw. 6. Route the harness end with the green wire to the passenger side and repeat the connector connection. 7. Mount the black converter box in a protected area away from spray and debris using the provided double-sided tape. 8. Route the black power wire from the battery as shown on the included CME-PCL-INS sheet. 9. Route the 4-flat connector to the center of the vehicle and out of the trunk when in use; store rolled up in the trunk when not in use. 10. Secure loose wires with provided cable ties. 11. Reinstall all removed items and install the 4-flat dust cover.
Drilling may be required. The ground wire must be secured to a clean grounding point. If an existing screw with nut is not available in the vehicle frame near the connector, you will need to drill a 3/32" pilot hole for the provided screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.

The converter box is black. The 4-flat connector is used to connect the trailer when in use.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If one is not available, drill a 3/32" pilot hole for the provided screw. The area must be clean and free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Mount the black converter box in a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Use the provided double-sided tape to adhere it. Failure to mount the box in a protected area can cause loss of warranty, product failure, overheating and potential fire.
When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll it up and store it in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Signal circuits are rated for 3.0 amps per side, and tail/running circuits are rated for 6.0 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Exceeding the product rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. The battery connection must be fuse-protected with a 10-amp maximum fuse.
