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 Chevy Equinox, GMC Terrain, Pontiac Torrent and Saturn Vue (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.
A CURT custom wiring harness (also called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT's custom wiring harnesses come into play. Custom wiring harnesses plug into your vehicle's electrical system using original equipment (OEM) connectors. Our custom wiring harnesses use two or more OEM connectors to plug in at the taillight assembly and provide a standard trailer socket to allow a trailer to be plugged into your vehicle's power system. This harness provides a 5-way flat connector socket and is designed to be a custom wiring harness for certain years of the GMC Terrain or Chevrolet Equinox (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). CURT custom wiring harnesses are long-lasting and quick to install. They come with dust covers to keep your connector clean when not in use and feature a one-year limited warranty to give you peace of mind.

Yes. Step 2 of the installation instructions states: "Remove existing M12 fasteners from outside surfaces of frame rails. If present, remove tie down brackets and return to customer."
1. On Chevy Equinox and GMC Terrain, remove the fascia panel at the center. 2. Remove existing M12 fasteners and tie down brackets from frame rails. 3. Raise hitch into position and fasten to bumper beam using M12 bolts and conical washers (or fishwire carriage bolts on Saturn Vue and some Equinox/Terrain models). 4. Install M12 bolts and conical washers on outside surfaces of frame rails. 5. Fishwire remaining carriage bolts, square hole spacers, and flange nuts through the end of bumper beam (Saturn Vue and some Equinox/Terrain models only). 6. Torque all fasteners to specification.
All M12 hardware must be torqued to 79 ft-lbs.
All 1/2" hardware must be torqued to 110 ft-lbs.
Follow these steps: 1. Spray the weldnut with penetrating oil and let it soak for 5 minutes. 2. Clean the weldnut with a wire brush and compressed air. 3. If necessary, use an M12-1.75 tap to clean the weldnut.
Yes. The installation notes state: "May need to enlarge holes to 17/32" to ensure clearance of 1/2" bolts." This applies when fishwiring carriage bolts and square hole spacers through the end of the bumper beam on Saturn Vue and some Chevy Equinox / GMC Terrain models.
Non-trailer loads may be applied to this product, but they must be supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty.

Yes, Curt part number 56594 is designed for Chevrolet Equinox and GMC Terrain vehicles. The manual does not specify model years or body styles, so contact Curt or your retailer to confirm your specific vehicle year and configuration are supported.
You will need a drill with a 3/32" bit (if you need to create a grounding point), a screwdriver, and basic hand tools. The manual provides cable ties and an eyelet with screw for grounding. If an existing grounding point with a screw and nut is available on the vehicle's frame, drilling may not be necessary.
Open the rear hatch. On each side of the vehicle, remove the two fasteners (marked A and B in the manual) holding each taillight assembly in place. Keep these fasteners for reinstallation.
The vehicle's taillight wiring harness is located behind the driver side taillight. It will have connectors similar to those on the T-Connector harness.
Locate the vehicle's taillight wiring harness behind the driver side taillight. Carefully separate the connectors without damaging the locking tabs. Insert the T-Connector end with the yellow wire between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the green wire connector.
Route the T-Connector end with the green wire down through the opening under the driver side taillight. Under the vehicle, route it across the backside of the bumper and up through the opening under the passenger side taillight. This routing ensures the 5-flat connector ends up near the center of the vehicle.
The T-Connector has a yellow wire, a green wire, and a white wire. The yellow and green wires connect to the taillight harness connectors. The white wire is used for grounding.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no suitable point exists, drill a 3/32" hole and secure the white wire using the eyelet and screw provided with the kit.
Drilling is required only if a suitable existing grounding point (a screw with nut in the vehicle's frame) is not available near the connector. If you must drill, use a 3/32" bit to create a hole for the white wire grounding eyelet.
Drill a 3/32" hole for the grounding eyelet if an existing screw with nut is not available on the vehicle's frame.
Before drilling, verify that miscellaneous items hidden behind or under any surface will not be damaged. This precaution avoids damage to vehicle components and personal injury.
Secure the 4-flat to the center of the vehicle in a convenient out-of-the-way location. Use the cable ties provided to secure any loose wires.
The Curt 56594 T-Connector is designed for Chevrolet Equinox and GMC Terrain vehicles. Confirm your specific model year with the manufacturer or retailer.

Yellow and green wires connect to the taillight harness connectors on the driver and passenger sides respectively. The white wire grounds the system to the vehicle frame.
Before drilling, verify that no hidden items behind or under any surface will be damaged. This prevents damage to vehicle components and personal injury.
