All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Buick Terraza, Chevy Uplander, Pontiac Montana and Saturn Relay (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 400 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 6,000 lbs. WD and 600 lbs. WDTW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
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 Pontiac Montana, Saturn Relay, Buick Terraza and Chevy Uplander (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 lists gross load capacity specifications for both weight-carrying and weight-distribution use, but the specific capacity values are not filled in on this copy of the manual. Contact Curt Manufacturing directly with your part number (13336 or 78227) to obtain the exact towing and tongue weight capacities. Always verify that the hitch capacity does not exceed your vehicle manufacturer's recommended towing capacity.
The kit includes: 2× 7/16" fishwire, 6× M10×1.5 hex head cap screws (HHCS) grade 10.9, 6× 3/8" conical washers, 2× 7/16"-14 UNC carriage bolts grade 8, 4× 7/16"-14 UNC serrated flange nuts grade 8, 2× hex tap bolts, and 2× 0.250" × 1.00" × 2.50" square hole spacers.
No drilling is required on current model vehicles. However, the manual notes that frame drilling may be required on older Montana vans. If you own an older Montana van, contact Curt Manufacturing or a professional installer to determine whether drilling is necessary for your specific vehicle.
You must remove: (1) the rubber exhaust hanger and lower exhaust hanger bracket on the passenger side, (2) the fascia support bar from the frame rails on both driver and passenger sides, and (3) the compressor from the driver side if equipped. All of these components are reused or reattached after the hitch is installed.
1. Remove rubber exhaust hanger and lower exhaust hanger bracket on passenger side. 2. Remove fascia support bar from frame rails on both sides. 3. Disconnect and lower compressor from driver side if equipped. 4. Fishwire 7/16" carriage bolts and spacers through access slots in frame rails, leaving them inside the frame rail. 5. Lift hitch into position and secure with M10 bolts and 3/8" conical washers, finger tighten. Finish fishwiring carriage bolts and spacers into position and secure with flange nuts. 6. Reattach exhaust hanger bracket (some models require it to pass through hitch side plate and attach to hitch mounting tab using 7/16" bolts and flange nuts). 7. Reattach fascia support brackets and compressor (trim compressor bracket before reinstalling). 8. Torque all fasteners to specification.
Fishwiring is the process of threading the 7/16" carriage bolts and spacers through the access slots in the frame rails before the hitch is lifted into position. The bolts and spacers are left inside the frame rail until the hitch is raised and secured. Do not remove the fishwire from the carriage bolt until the hitch is raised into position and secured.
Torque all 7/16" fasteners to 70 ft-lb and all 10mm (M10) fasteners to 45 ft-lb. This applies to the carriage bolts, flange nuts, and M10 hex head cap screws.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain the integrity and safety of the installation.
Do not exceed your vehicle manufacturer's recommended towing capacity. The hitch has its own capacity ratings, but your vehicle's towing limit is the controlling factor. Always follow the lower of the two limits.

The Curt 56077 is a custom wiring connector designed for S-class vans (Buick Terraza, Chevrolet Uplander, Pontiac Montana SV6, and Saturn Relay). It connects to the vehicle's taillight wiring harness to enable trailer lighting functions. The connector is a 4-flat type that routes to the center of the vehicle and out of the trunk for use, and can be rolled up and stored inside the trunk when not in use.
You will need a panel trim removal tool. The manual also recommends having a test light or a properly wired trailer available to test the connector after installation to ensure proper function.
Open the vehicle tailgate, then remove the threshold trim along the rear doors and the interior trim panel on the driver side. Behind this trim panel you will locate the vehicle taillight wiring harness connectors. Use a panel trim removal tool to avoid damage.
Locate the vehicle taillight wiring harness connectors behind the driver side interior trim panel. If the connectors are already connected, separate them carefully without damaging the locking tabs. Insert the custom wiring harness end between the separated connectors, ensuring the connectors are fully inserted with locking tabs in place.
Route the 4-flat connector to the center of the vehicle and out of the trunk when in use. 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.
After connecting the harness, reinstall all items you removed during installation. Install the provided 4-flat dust cover to help prevent corrosion. Then test for proper function by using a test light or connecting a properly wired trailer.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire. Check your vehicle owner's manual or contact the vehicle manufacturer for the tow vehicle lamp load rating.
