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 and Chevy Trax (excluding GX; 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.
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.

Two people may be required to ease installation. The manual rates this as a moderate to challenging difficulty level.
Professional installation takes approximately 25 minutes. Novice (DIY) installation takes approximately 60 minutes.
1. Lower rear exhaust hangers from one location on each side (or front center if needed). 2. Trim wheel well plastic on some model years if needed for flush fit. 3. Enlarge frame access holes to fit SP2 spacers. 4. Fishwire spacers and 7/16" bolts through access holes, raise hitch into position, and loosely secure with 7/16" nuts. 5. If no weldnuts exist, fishwire hardware for side mounting points and secure all 7/16" hardware; if weldnuts exist, secure with M12 bolts and 1/2" conical washers. 6. Torque all fasteners to specification and raise exhaust hangers back into position.
Fishwiring is a technique using 7/16" fishwire (included in the kit) to thread fasteners through access holes in the vehicle frame and into mounting points. It is required because the hitch mounts through the frame rails at locations where direct bolt access is not available. The fishwire guides the bolts into position so they can be secured with nuts.
The fastening method depends on your vehicle's frame: if weldnuts already exist in the frame, use M12 bolts and 1/2" conical washers in the side mounting plates. If no weldnuts exist, fishwire the 7/16" hardware through the frame rail and hitch side plates and secure with 7/16" serrated flange nuts.
The frame access holes must be enlarged to accommodate the 0.250 x 0.88 x 2.25" square hole spacers (CM-SP2) included in the kit. The manual specifies an 0.88" diameter enlargement on the diagram but does not provide exact hole size specifications. Contact CURT Technical Support at 877-287-8634 for precise dimensions.
Yes, caulking may need to be trimmed around side mounting holes if present. This is mentioned as a possible requirement during the exhaust lowering step.
On some model years, the wheel well plastic on each side of the vehicle near the frame rails will need to be trimmed to provide a flush fit for the hitch side plates. The manual does not specify which model years require this. Consult with your installer or contact CURT Technical Support at 877-287-8634 to confirm if your vehicle requires this modification.
Safety glasses must be worn at all times during installation. When cutting frame material or plastic, be sure to avoid the vehicle brake lines. If lowering the exhaust at the front center, lower it slowly and support it from underneath during installation.
After installation, periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This ongoing maintenance is critical to safe operation.
The manual states to periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound, but does not specify an exact inspection interval. For safety, inspect before each towing use and at regular intervals during the towing season.
CURT Manufacturing warrants this product to be free of defects in material and/or workmanship at the time of retail purchase by the original purchaser. If defective, CURT may repair or replace the product at their option when returned prepaid with proof of purchase. Alteration, misuse, or improper installation voids the warranty.
The CURT 11527 complies with safety specifications and requirements for connecting devices and towing systems of the state of New York, V.E.S.C. Regulation V-5 and SAE J684.
On some model years, the wheel well plastic on each side of the vehicle near the frame rails will need to be trimmed to provide a flush fit for the hitch side plates. Carefully trim away the plastic while avoiding the vehicle brake lines. If the fit is still not flush after plastic trimming, verify that the frame access holes have been enlarged sufficiently to accommodate the SP2 spacers.
The frame access holes must be enlarged to fit the 0.250 x 0.88 x 2.25" square hole spacers. Use a die grinder with a cut-off wheel to enlarge the holes. Be sure to avoid the vehicle brake lines when cutting the frame material away. If you are uncertain about the correct hole size, contact CURT Technical Support at 877-287-8634.
Lower the rear exhaust hangers from one location on each side of the vehicle. If this does not provide sufficient clearance, the exhaust can also be lowered at one location at the front center of the vehicle. This location must be lowered slowly and supported from underneath during installation. Raise the exhaust hangers back into position after the hitch is secured.
Yes, the Curt 56363 is designed for Buick Encore SUVs, Mini & Full-Sized Vans (S-class). The harness is installed behind the driver and passenger side rear access panels. Verify your vehicle is a 12-volt negative ground system before installation.
The Curt 56363 is a custom wiring harness with a powered converter that connects your vehicle's taillight system to a trailer connector. It allows you to tow a trailer with integrated lighting by converting your vehicle's lighting signals to the trailer's 4-flat connector.
No. The converter system is designed only for 12-volt negative ground systems. Check your vehicle owner's manual or contact the vehicle manufacturer to confirm your system type before purchasing.
You will need: 10mm socket, ratchet, socket extension, panel trim removal tool, flat blade screwdriver, wire stripper, crimping tool, T-45 Torx bit, and side cutter.
Yes. You must disconnect the negative battery cable before wiring the power wire to the battery. This is a critical safety step to prevent electrical shock and short circuits during installation.
The custom wiring harness connects between the vehicle's taillight wiring harness connectors. The harness end with the yellow wire connects on the driver side, and the harness end with the green wire connects on the passenger side. Both are located behind the rear access panels. The connectors are inserted between the separated taillight housing connectors with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The converter should be mounted in a location where it will not be disturbed or damaged.
Drilling may be required. Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, drill a 3/32" pilot hole. The area must be free of rust, dirt and paint. Always check for miscellaneous items hidden behind or under surfaces before drilling to avoid damage and personal injury.
The battery connection must be fuse protected with a 10 amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Install the fuse after all other installation steps are complete.
The power wire must be 12 GA (12 gauge) or larger. Route this wire from the vehicle battery to the converter, taking care to avoid pinch points and hot or rotating components.
The wiring harness uses the following color codes: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight, and White = Ground. The converter box has a black power wire that connects to the positive battery terminal.
Signal circuits (left turn, right turn, brake) are rated at 3.0 amps per side. Tail and running light circuits are rated at 6.0 amps total. Do not exceed these product ratings or the tow vehicle lamp load rating, whichever is lower.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the vehicle. When in use, route it to the center of the vehicle. Secure any loose wires with the provided cable ties.
After installation, reinstall all items removed during the install, including the rear scuff panel, storage trays, and side trim panels. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
Route the 12 GA power wire carefully to avoid 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 wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties.
1. Open the tailgate and remove all trunk floor coverings. 2. Using a 10mm socket, remove the two cargo tie downs securing the rear scuff panel, then pull the scuff panel straight up. 3. Using a T-45 Torx bit and extension, remove fasteners securing the storage trays and remove them. 4. Remove the cargo tie down securing the side trim panel using a 10mm socket. 5. Use a trim panel removal tool to pull back the side trim panel. 6. Locate and separate the taillight wiring harness connectors.
Secure the white ground wire using the ring terminal and provided screw. Attach it to a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole. The area must be free of rust, dirt and paint.
If using the converter as a powered module for a two-wire system, the red brake wire must be grounded. This is a specific configuration requirement for two-wire trailer systems.
Two cargo tie downs secure the rear scuff panel. Remove them using a 10mm socket. After removal, pull the scuff panel straight up, taking care not to damage the alignment tabs on the back.
Storage trays are secured with fasteners that require a T-45 Torx bit and extension to remove. Use a ratchet with the socket extension to access and remove these fasteners.
Yes, the Curt 56363 is designed for Buick Encore SUVs, Mini & Full-Sized Vans (S-class) with 12-volt negative ground systems.
You need: 10mm socket, ratchet, socket extension, panel trim removal tool, flat blade screwdriver, wire stripper, crimping tool, T-45 Torx bit, and side cutter.
Yes, disconnect the negative battery cable before wiring the power wire. This is required for safety.
Drilling may be required if no existing screw with nut is available in the vehicle frame. If needed, drill a 3/32" pilot hole in a rust-free, clean area.
The battery connection must use a 10 amp maximum fuse. Exceeding this can cause overheating and fire.
Use 12 GA (12 gauge) wire or larger for the power lead from the battery to the converter.
Use an existing grommet, add a new grommet, or apply silicone to protect the power wire from sharp edges when passing through sheet metal.
After installation is complete, test for proper function using a test light or by connecting a properly wired trailer. This will verify that all signal circuits (left turn, right turn, brake) and tail/running lights are functioning correctly.
