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, Chevy Venture, Oldsmobile Silhouette, Pontiac Montana and Pontiac Trans Sport (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.

Yes, the 05 - 07 Buick Terraza Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13344 (Part #CHW-224) is designed to fit the 2005-2007 Buick Terraza.
The 05 - 07 Buick Terraza Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13344 (Part #CHW-224) fits 2005-2007 Buick Terraza models. The 2007 model year is the last year covered by this part number. For newer models, check for an updated version.
The 05 - 07 Buick Terraza Curt 2", Class 3 Trailer Tow Hitch + 4-flat Wiring Kit 13344 (Part #CHW-224) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Curt 13344 Class II receiver hitch fits 97-07 Chevrolet Venture, 97-05 Oldsmobile Silhouette, 97-05 Pontiac Trans Sport, 05-07 Montana SV6, 08-current Montana SV6 (Canada only), 05-08 Chevrolet Uplander, 05-07 Saturn Relay, and 05-07 Buick Terazza. Fitment varies by wheelbase: short wheelbase models (2004 and older) use different spacer block placement than long wheelbase models. Verify your vehicle's year, model, and wheelbase before purchasing.
The Curt 13344 has a gross load capacity of 6000 lbs trailer weight and 600 lbs tongue weight when used as a weight-carrying hitch. When used as a weight distribution hitch, the capacity is 4000 lbs trailer weight and 400 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than these ratings.
Required tools are: ratchet, 6" extension, 3/4" socket, 11/16" socket, 15mm socket, 10mm socket, pliers, drill with 17/32" bit, and torque wrench. A drill is essential because installation requires drilling 1/2" holes in the vehicle frame rails.
Yes. Step 1 of the installation requires lowering the vehicle exhaust by lowering the exhaust hanger on the passenger side. This is necessary to provide clearance for the hitch installation. The exhaust hanger is reattached in Step 7 after the hitch is secured.
If your vehicle has a load leveling compressor, it must be lowered during installation. Step 2 requires lowering the load leveling compressor on the driver's side using one M10 bolt and two M6 nuts. If necessary, the vertical tab on the compressor bracket may need to be trimmed to clear the adjacent M10 bolt. The compressor is reattached in Step 7.
Yes, drilling is required. Step 4 requires drilling 1/2" holes in the vehicle frame rails using the rearmost holes in the hitch side plate as a template. On long wheelbase models, an additional 1/2" hole must be drilled through the forwardmost hole on the passenger side plate. On short wheelbase models, the forwardmost hole aligns with an existing slot in the frame rail and does not require drilling.
Possibly. Step 2 notes that if necessary, the vertical tab on the compressor bracket should be trimmed to clear the adjacent M10 bolt. This is not always required; trim only if the compressor bracket interferes with the M10 bolt during lowering.
Torque all 1/2" hardware to 110 lb-ft. Torque all M10 fasteners to 45 lb-ft. Torque all M6 fasteners to 9 lb-ft. These specifications apply to Step 8 of the installation.
The kit includes: 2 handle nuts (1/2-13 UNC), 2 hex head cap screws (1/2-13 UNC, 1-1/2"), 2 standard washers (1/2"), 1 serrated flange nut (1/2-13 UNC), 4 hex head cap screws (M10x1.5, 45mm), 4 standard washers (3/8"), 1 carriage bolt (1/2-13 UNC, 2"), 1 square hole spacer (.250 x 1.50 x 2.00"), 1 U-shape spacer (.250 x 1.75 x 2.00"), 4 round hole spacers (.250 x 2.00 x 2.00"), 2 round hole spacers (.188 x 1.50 x 2.00"), and 1 fishwire (1/2").
Follow these steps in order: (1) Lower the exhaust hanger on the passenger side. (2) If present, lower the load leveling compressor on the driver's side. (3) Raise the hitch into position and install M10 bolts into existing weldnuts on both sides. (4) Using the rearmost holes as a template, drill 1/2" holes in the frame rails (long wheelbase models require an additional hole on the passenger side). (5) Install the fishwire carriage bolt and spacer blocks on the passenger side through the existing slot. (6) Install the handle nut and hex bolt through the frame rail holes. (7) Reattach the exhaust hanger and load leveling compressor. (8) Torque all fasteners to specification.
On short wheelbase models (2004 and older), place 2 spacer blocks between the frame rail and hitch. On long wheelbase models, place 2 spacer blocks between the hitch and the flange nut. There may be unused spacers after installation is complete. The specific spacer types (square hole, U-shape, or round hole) are determined by the mounting configuration for each wheelbase.
On the passenger side, pass the fishwire carriage bolt and blocks through the existing slot in the frame rail down into the forwardmost hole. Secure using spacer blocks, lock washer, and nuts. The exact configuration depends on wheelbase: short wheelbase models place 2 spacer blocks between the frame rail and hitch, while long wheelbase models place 2 spacer blocks between the hitch and flange nut.
On all-wheel drive models, when reattaching the exhaust hanger in Step 7, it is necessary to pass the exhaust hanger through a 3" long slot in the side plate and use 2 1/4" spacer blocks to reattach the exhaust hanger bracket.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This ongoing inspection helps maintain safe operation and prevents loosening of fasteners due to vibration and use.
The manual does not provide the hitch weight specification. Contact Curt Manufacturing or consult the product specification sheet for this information.
Yes, the Curt 13344 fits 97-07 Chevrolet Venture, 97-05 Pontiac Trans Sport, and related minivans (Oldsmobile Silhouette, Montana SV6, Chevrolet Uplander, Saturn Relay, Buick Terazza). Fitment depends on wheelbase: verify your model year and wheelbase before installation.
Yes. Installation requires drilling 1/2" holes in the vehicle frame rails. Long wheelbase models require two holes on the passenger side; short wheelbase models require one hole (the other aligns with an existing slot).
Yes. The exhaust hanger on the passenger side must be lowered. If your vehicle has a load leveling compressor, it must be lowered on the driver's side. Both are reattached after the hitch is secured.
Torque 1/2" hardware to 110 lb-ft, M10 fasteners to 45 lb-ft, and M6 fasteners to 9 lb-ft. Use a torque wrench and verify all fasteners after installation.
Required tools: ratchet, 6" extension, 3/4" socket, 11/16" socket, 15mm socket, 10mm socket, pliers, drill with 17/32" bit, and torque wrench.

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.
Yes. Before drilling or removing any trim panels, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. When separating the vehicle's taillight wiring harness connectors, take care not to damage the locking tabs.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring connector will function properly.
