All Hardware and Installation Instructions Included!
However you define adventure -- whether it's climbing onto the back of a mountain bike, hunting from the top of a tree stand or camping with the family a long way from nowhere -- CURT class 1 hitches provide a light-duty towing receiver to help you Bring It. Each is made to fit a specific vehicle, providing easier installation, a better fit and optimal towing capacity. Custom class 1 trailer hitches are available for a variety of smaller vehicle types, including the compact car, crossover, minivan and small SUV. This particular class 1 hitch is designed to be a custom hitch for certain years of the Buick Encore GX and Chevrolet Trailblazer (to verify vehicle compatibility, see the CURT application guide at curtmfg.com). Tested in accordance with SAE J684, it offers a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. It is equipped with 1-1/4" receiver tube opening to accept a ball mount shank or other hitch mount. This class 1 hitch also comes with all necessary mounting hardware. With its lightweight design and smaller receiver tube size, a class 1 hitch is especially useful for adding cargo space with a hitch-mounted bike rack or cargo carrier. They can also typically be used to tow small trailers such as a utility trailer, kayak trailer or teardrop camper (never exceed the lowest weight capacity of any towing component; i.e. the vehicle, hitch, trailer, etc). Though CURT class 1 trailer hitches are only intended for light-duty towing, we apply the same principles of quality as we do to the rest of our rear mount hitches. Each class 1 hitch is made with hands-on engineering, high-strength steel and precise welding. We use a co-cured finish of liquid A-coat, inside and out, and durable black powder coat to provide a lasting defense against rust, chips and UV rays.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. 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 Buick Encore GX and Chevrolet Trailblazer (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.

No drilling is required. The installation uses existing vehicle hardware (M10 screws and nuts) and involves removal of components, trimming of the rear bumper fascia and underbody panel, and caulking around the bumper beam.
All M10 hardware (nuts and screws) must be torqued to 32 lb-ft. Use a torque wrench to ensure proper tightening during installation.
Yes. The installation requires trimming of the rear bumper fascia and trimming of the underbody panel to 2-5/8" wide x 1-3/8" tall. Caulk around the bumper beam must also be trimmed.
Wear safety glasses at all times during installation. Gloves are recommended when using cutting tools. Support the taillight to avoid damaging electrical wires. Ensure electrical connectors are out of the way when trimming caulk and during hitch installation.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. Refer to specified torque specifications (32 lb-ft for M10 hardware) when checking hardware.
The CURT 11612 uses existing vehicle hardware for installation. No additional fasteners are included with the product. The installation reuses the vehicle's existing M10 screws and nuts from the bumper beam mounting points.
Installation requires removal of: wheel well trim, taillights, rear bumper fascia, and bumper beam. All of these components are reinstalled in Step 10 after the hitch is mounted. Fasteners removed during disassembly are set aside and reused.
The hitch is raised into position over the existing M10 screws on both the driver-side and passenger-side frame rails. The bumper beam is then placed over the hitch, and the three M10 nuts on each side are loosely installed. All M10 hardware is then torqued to 32 lb-ft.
Yes. On Chevrolet Trailblazer only, you must press on a tab located inside the rear bumper fascia near where the taillight and hatch intersect during removal. This step is not required for other compatible vehicles.
The installation is rated as "Easy" difficulty level based on time and effort involved. However, difficulty may vary depending on installer expertise, vehicle condition, and availability of proper tools. The manual recommends reading all instructions thoroughly before beginning and using proper tools to improve installation quality and reduce time required.
The rear bumper fascia must be trimmed during removal (Step 5-6). Additionally, caulk around the bumper beam on both sides must be trimmed (Step 7). The underbody panel must be trimmed to 2-5/8" wide x 1-3/8" tall (Step 10). Use a utility knife for trimming and wear gloves for safety.
Yes. The manual indicates that electrical connectors may be present on the rear bumper fascia and frame. In Step 6, disconnect all electrical connectors from the rear bumper fascia if applicable. In Step 7, remove all electrical connectors from the frame if applicable. All connectors are reinstalled in Step 10. Support the taillight to avoid damaging electrical wires during removal.
The installation follows a specific 10-step sequence: (1) Remove wheel well trim and fascia screws, (2) Remove hatch screws, (3) Remove underbody panel fasteners, (4) Remove taillight screws and taillight, (5) Pull rear bumper fascia, (6) Remove rear bumper fascia and disconnect electrical connectors, (7) Trim caulk around bumper beam, (8) Remove bumper beam M10 nuts, (9) Install hitch and bumper beam with M10 nuts torqued to 32 lb-ft, (10) Trim underbody panel and reinstall all components.
The M10 nuts should be loosely installed in Step 9 before the hitch is in final position. They are then torqued to 32 lb-ft once the hitch is properly positioned over the existing M10 screws on both sides of the vehicle.
After installation, verify that all mounting hardware is tight and structural components are secure. Ensure all M10 hardware is torqued to 32 lb-ft. Confirm that all electrical connectors are properly reinstalled and functional. Check that the rear bumper fascia, taillights, wheel well trim, and underbody panel are properly reinstalled. Perform periodic inspections to ensure hardware remains tight.
The Curt 56541 includes a custom wiring harness with a 4-flat connector, a dust cover for the connector, and all necessary hardware for installation. The harness is designed to connect to the vehicle's factory black tow plug connector located in the cargo area on the driver side near the threshold.
The Curt 56541 is designed for SUVs and Vans (S). Your vehicle must have a factory black tow plug connector in the cargo area on the driver side near the threshold. Consult your vehicle owner's manual or contact the vehicle manufacturer to confirm your vehicle has this connector before purchasing.
You will need a ratchet, a 10mm socket, a panel trim removal tool, and a test probe. These tools are required to disconnect the battery, remove the rear threshold plate, and test the harness after installation.
Yes, disconnecting the battery is required. Locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation. Reconnect it only after all wiring is complete and tested.
After disconnecting the negative battery terminal, fasten the wire down and away from the battery to prevent accidental reconnection or contact with the positive terminal during installation.
The Curt 56541 has the following electrical ratings: Signal circuits are rated at 7.5 amps per side, and Tail/Running circuits are rated at 7.5 amps total. 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 vehicle's specific lamp load rating.
The black tow plug connector is located in the cargo area on the driver side near the rear threshold plate. You will need to remove the rear threshold plate to access it. The connector is where you will insert the custom wiring harness.
1. Disconnect the negative battery terminal and fasten it away from the battery. 2. Open the rear hatch and remove all floor coverings. 3. Using a panel trim tool, carefully pull up the rear threshold plate. 4. Locate the black tow plug connector in the cargo area on the driver side near the threshold. 5. Insert the custom wiring end into the connector, ensuring it is fully inserted with locking tabs in place. 6. Reinstall the threshold and floor coverings. 7. Reconnect the negative battery terminal and install the provided 4-flat dust cover.
When not in use, roll up the 4-flat and store it in a convenient, out-of-the-way location inside the rear hatch, under the floor covering. This protects the connector from damage and keeps it organized.
When in use, route the 4-flat to the center of the vehicle and out of the rear hatch. Be careful to avoid routing it through any pinch points between the hatch door and the vehicle, and stay clear of the hatch lock mechanism to prevent damage to the connector.
The locking tabs secure the custom wiring harness to the factory tow plug connector. When you insert the custom wiring end, push it in fully until you hear or feel the locking tabs engage. This ensures a secure, reliable connection.
After reconnecting the negative battery terminal, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. This confirms that all connections are correct and the product is working properly before use.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval, so consult your vehicle owner's manual or contact Curt Manufacturing for recommended maintenance schedules.
The provided 4-flat dust cover helps prevent corrosion of the connector when it is not in use. Install it after reconnecting the battery to protect the connector from moisture and environmental damage.
Laying tools across the positive battery terminal (typically noted with red covers or a red '+' symbol) can cause a ground short, leading to sparks and/or electrical shocks. Keep tools clear of the positive terminal during installation to prevent injury and damage.
