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 Chevrolet Equinox and GMC Terrain (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 525 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 Chevrolet Equinox and GMC Terrain (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.

Yes, the 18 - 24 GMC Terrain Excluding diesel Curt 1-1/4" Class 2 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 12201 (Part #5W-CHW-1685) is designed to fit the 2018-2024 GMC Terrain.
The 18 - 24 GMC Terrain Excluding diesel Curt 1-1/4" Class 2 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 12201 (Part #5W-CHW-1685) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the CURT 12201 is designed for 2018-Present Chevrolet Equinox and GMC Terrain SUVs. The manual confirms compatibility with these models and years. Verify your vehicle matches these specifications before purchasing.
The CURT 12201 is rated for a maximum trailer weight of 3,500 lbs and a tongue weight of 525 lbs when used as a weight-carrying hitch. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
Non-trailer (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. Contact CURT at www.curtmfg.com or 877-287-8634 for information on the stabilizing straps.
Required tools are: ratchet, 15 mm socket, 3/4" socket, 6" socket extension, T15 Torx bit socket, pry bar, torque wrench, rotary tool, and safety glasses. Using proper tools will greatly improve installation quality and reduce installation time.
The manual does not specify whether the battery must be disconnected. Contact CURT technical support at 877-287-8634 for guidance on this step.
No drilling is required. The installation is described as "no drill." However, hole enlargement is required on both the driver and passenger side frame rails to allow the hardware to fit. A rotary tool is needed to enlarge the access holes.
No permanent modifications are required. The exhaust is temporarily lowered (not permanently removed or modified) and then reinstalled after hitch installation. The access holes on the frame rails are enlarged using a rotary tool, but this is a minor enlargement to accommodate the fishwire hardware.
Two people may be required to ease installation. While one person may be able to complete the installation, having a second person will make the process easier, particularly when raising the hitch into position.
The first step is to locate and remove the two Torx screws from the rear fascia. Save these screws for reinstallation after the hitch is secured.
The exhaust must be temporarily lowered to provide access to the frame rail mounting points. The exhaust is lowered by removing four bolts from the rear exhaust hanger brackets (two per side) using a 15 mm socket, and then removing the exhaust rubber isolator in front of the muffler. The exhaust is reinstalled after the hitch is secured.
Fishwire is a flexible wire tool used to route fasteners through tight or hard-to-reach spaces. In the CURT 12201 installation, you use the fishwire to thread one 1/2" carriage bolt and one spacer into each of the three mounting holes in both frame rails, accessing them through the access holes. This allows fastening without drilling.
Six 1/2" carriage bolts (part 10-10287) and six spacers (part CM-SP6) are used. These are installed through the access holes using fishwire into the three mounting holes on each frame rail (three per side). Six 1/2" hex flange nuts (part 20-00062) secure the bolts.
All 1/2" hardware (carriage bolts and hex flange nuts) must be torqued to 110 ft-lb. A torque wrench is required to achieve this specification.
After the hitch is torqued to specification, reinstall the two Torx screws that were removed from the rear fascia in step 1, and reinstall the exhaust that was lowered in steps 2-3.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing maintenance is important for safe operation.
Safety glasses must be worn at all times during installation. When lowering the exhaust, be sure to support it to prevent it from falling. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
The installation difficulty is rated as moderate. The manual recommends reading all instructions thoroughly before beginning, and notes that using proper tools will greatly improve installation quality and reduce installation time.
Yes, the hitch includes all required hardware: six 1/2" carriage bolts (10-10287), six 1/2" hex flange nuts (20-00062), six spacers (CM-SP6), and six pieces of 1/2" fishwire (1_2 FISHWIRE). No additional fasteners are required for installation.

Part 56429 is a custom wiring harness for SUVs and vans. It connects your vehicle's electrical system to a trailer via a 4-flat connector mounted near the hitch. The harness provides signal circuits (7.5 amps per side) and tail/running circuits (7.5 amps total) to control trailer lights.
Part 56429 is designed for SUVs and vans. The wiring connector is located behind the center of the rear bumper (location S6). Check your vehicle's owner's manual to confirm your vehicle has a rear bumper-mounted connector location. If your vehicle does not have a connector in this location, this product may not be compatible.
You will need a flat blade screwdriver and a cutting tool. You will also need a test light, 4-flat tester, or a functioning trailer to verify the harness is working after installation.
Yes. Before beginning installation, locate your vehicle battery using your owner's manual and disconnect the negative battery terminal. Fasten this wire down and away from the battery during installation. Reconnect it after all other installation steps are complete.
1. Locate the vehicle wiring connector along the rear bumper (it will look similar to the custom connector end). 2. Separate the vehicle connector from the weather seal connector carefully, taking care not to damage the locking tabs. 3. Insert the custom wiring connector end fully into the vehicle connector, ensuring the locking tabs are in place. 4. Zip tie the harness into place and mount the 4-flat connector near the hitch.
After connecting the harness, reinstall all items you removed during installation. If you disconnected the negative battery terminal at the start, reconnect it now. Install the provided 4-flat dust cover to help prevent corrosion. Then verify the harness is functioning by connecting the battery and testing with a test light, 4-flat tester, or a functioning trailer.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific lamp load rating.
Signal circuits are rated at 7.5 amps per side. Tail and running circuits are rated at 7.5 amps total.
After reconnecting the battery, verify the harness is functioning by using a test light, 4-flat tester, or by connecting a properly wired trailer. This confirms all signal and running circuits are working correctly before towing.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. This helps prevent electrical failures and corrosion.
The 4-flat dust cover is a protective cover provided with part 56429. Install it on the 4-flat connector after completing the wiring harness installation to help prevent corrosion of the connector.
Mount the 4-flat connector near the hitch after zip tying the harness into place.
You need a flat blade screwdriver, cutting tool, and a test light or 4-flat tester to verify installation. A functioning trailer can also be used for testing.
Yes, disconnect the negative battery terminal before starting installation and reconnect it after completing all other steps.
Signal circuits: 7.5 amps per side. Tail/running circuits: 7.5 amps total.
