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 Chevrolet Trailblazer and Buick Encore GX (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 2,000 lbs. GTW and 200 lbs. TW. 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 Buick Encore (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.

Part number 56488 is a powered converter lead and wiring harness system manufactured by Curt Manufacturing. It converts vehicle taillight signals (left turn, right turn, brake, and tail/running lights) to a 4-flat trailer connector. The system includes a black converter box that processes the signals and a custom wiring harness with yellow and green wires that connect to the vehicle's taillight connectors.
The Curt 56488 is designed for SUVs and Vans with 12 volt negative ground electrical systems. The manual does not list specific vehicle models, years, or trim levels. Contact the manufacturer or consult a fitment database to confirm compatibility with your specific vehicle before purchasing.
No. The Curt 56488 converter system is designed for 12 volt negative ground systems only. It will not function on vehicles with 12 volt positive ground electrical systems. Check your vehicle owner's manual to confirm your vehicle uses a 12 volt negative ground system before installing this product.
Required tools are: ratchet, 10mm socket, socket extension, T-45 Torx bit, panel trim removal tool, cutting tool, wire crimper, wire stripper, flathead screwdriver, and electrical tape. The manual notes that proper tools will improve the quality of installation and reduce the time required.
The kit includes a custom wiring harness with yellow and green wires, a black converter box, double-sided tape for mounting the converter box, cable ties for securing wires, a 4-flat dust cover, a white ground wire with ring terminal, a fuse holder, a screw for the ground wire connection, and butt connectors. The manual shows a Hardware Photo on page 1 but does not itemize each component by name.
Yes. Step 1 requires you to disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery while completing the installation process. The negative battery terminal must remain disconnected until all wiring steps are complete and you are ready to test the system.
Open the vehicle tailgate and remove all trunk floor coverings (Step 2). Then use a 10mm socket to remove the two cargo tie downs securing the rear side panels, and use a trim tool to remove the scuff panel by pulling straight up, taking care not to damage the alignment tabs (Step 3). Remove the storage trays using a T-45 Torx bit and extension (Step 4). These steps provide access to the taillight wiring harness connectors.
Use a panel trim removal tool to pull back the side trim panel on the driver side, taking care not to damage the push fasteners. Locate the vehicle taillight wiring harness connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side with the green wire (Steps 5-6).
Locate a flat clean surface behind the trunk liner on the driver side that is out of the path of spray and debris from the rear wheels and road. Adhere the black converter box using the provided double-sided tape or cable ties. Failure to mount the box in a protected area can cause loss of warranty, product failure, overheating, and potential fire.
Route the black power wire from the vehicle battery as shown on the last page of the manual (page 4). The wire must be 12 GA or larger. Route it to avoid any pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties.
The wiring harness uses the following colour code: Yellow = Left turn, Green = Right turn, Red = Brake, Brown = Taillight. The custom wiring harness has a yellow wire for the driver side and a green wire for the passenger side. The converter box also has a white ground wire and a black power wire that connects to the vehicle battery positive terminal.
The battery connection must be fuse-protected with a maximum of 10 amps. The fuse holder included with the kit has a 15 amp fuse maximum. Install the fuse after all other steps are complete. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Signal circuits (left turn and right turn): 5.0 amps per side. Tail/Running circuits: 7.5 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Attach the ring terminal of the white ground wire to the vehicle body using the screw provided. If necessary, drill a 3/32 inch hole to mount the ground wire. Ensure the connection is secure and on a clean, bare metal surface of the vehicle chassis.
Do not lay tools across the positive battery terminal (typically noted with red covers or a '+' symbol), as this can cause a ground short resulting in sparks and/or electrical shocks. Disconnect the negative battery terminal before wiring the power wire. The battery connection must be fuse-protected with a 10-amp maximum. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Before drilling, check for miscellaneous items that may be behind or under any surface. This prevents personal injury or property damage. The only drilling required is a 3/32 inch hole for the white ground wire connection if an existing mounting point is not available.
Once the 12 volt power wire is connected to the harness, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. All steps must be followed to ensure the product will function properly.
Reinstall all items removed during installation. If the negative battery terminal was disconnected at the beginning, reconnect it. Install the provided 4-flat dust cover to help prevent corrosion. When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll up and store in a convenient, out-of-the-way location inside the trunk.
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 or other maintenance procedures.

Two trimming tasks are required: (1) the rear bumper fascia must be trimmed to allow the hitch to fit, and (2) the caulk around the bumper beam must be trimmed on both sides. Additionally, the underbody panel must be trimmed to 3-1/2" wide x 1-3/8" tall. Use a utility knife for these cuts.
Yes. The manual requires trimming of the rear bumper fascia as part of the installation process. This is a permanent modification. The trimmed fascia is then reinstalled in Step 10.
Follow this removal sequence: (1) Remove wheel well trim and fascia screws (Step 1); (2) Remove hatch screws (Step 2); (3) Remove underbody panel fasteners (Step 3); (4) Remove taillight screws and taillight (Step 4); (5) Pull rear bumper fascia (Step 5); (6) Remove rear bumper fascia and disconnect electrical connectors (Step 6); (7) Trim caulk around bumper beam (Step 7); (8) Remove bumper beam by unbolting M10 nuts (Step 8). This sequence allows safe access to the hitch mounting points.
In Step 9, raise the hitch into position over the existing M10 screws on both sides of the vehicle. Place the bumper beam over the hitch. Loosely install the three M10 nuts removed in Step 8 on both sides. Ensure electrical connectors are clear of the hitch and bumper beam during this process. After positioning, torque all M10 hardware to 32 lb-ft.
In Step 9, loosely install the three M10 nuts on both sides of the vehicle. Do not fully tighten them at this stage. After all components are positioned and the bumper beam is in place, torque all M10 hardware to 32 lb-ft.
Step 10 is the final reassembly step. Trim the underbody panel to 3-1/2" wide x 1-3/8" tall. Then reinstall all electrical connectors, the rear bumper fascia, the taillights, and all fasteners removed in Steps 1-4 and 6-7. This restores the vehicle to its original appearance.
Yes. The manual states "If applicable, disconnect all electrical connectors from the frame" in Step 7 and "If applicable, disconnect all electrical connectors" from the rear bumper fascia in Step 6. These connectors must be kept clear during hitch and bumper beam installation (Step 9) and reinstalled in Step 10. Support the taillight carefully to avoid damaging electrical wires when removing it in Step 4.
