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 Mazda 3 (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 Honda Civic sedan (except hybrid), Honda Fit 5door sport, Honda Accord without LED taillights, Mazda 3, Mazda CX5 and Mitsubishi Galant sedan, 2.4L, single exhaust (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 11386 is designed for Mazda 3 Sedan and Hatchback. The installation uses different attachment holes depending on model year: forward holes for 2004–2007 models and rearward holes for 2008 and newer models. Compatibility with other Mazda 3 body styles or generations is not specified in the manual.
The manual specifies a gross load capacity of 2,000 lbs trailer weight and 200 lbs tongue weight when used as a weight-carrying hitch. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
You will need a 1/2" drill bit to enlarge the four attachment holes. A torque wrench capable of 70 lb-ft is required for final fastener tightening. The manual does not specify other tools required.
Yes. You must remove the two plastic fasteners from the lower fascia before beginning installation. These are reinstalled after the hitch is secured.
Yes. You must enlarge four attachment holes using a 1/2" drill bit. This is a permanent modification to the vehicle frame and bumper structure.
1. Remove the two plastic fasteners from the lower fascia. 2. Enlarge the four attachment holes using a 1/2" drill bit. 3. Fishwire bolts and square hole spacers into place through the end of the frame. 4. Raise hitch into position and snug fasteners. 5. Fishwire remaining bolts and spacers into position through the end of the inner bumper structure. 6. Reinstall plastic fascia fasteners. 7. Torque all fasteners to 70 lb-ft.
Fishwire is a technique for routing bolts and spacers through tight spaces. In this installation, you thread the bolts and square hole spacers through the end of the frame and inner bumper structure using the fishwire method. Two 7/16" fishwires are included in the parts kit for this purpose.
All fasteners must be torqued to 70 lb-ft. This is the final torque value applied after the hitch is raised into position and all fasteners are snug.
The kit includes four 7/16-14 UNC Grade 8 carriage bolts (1-1/4" long), four 7/16-14 UNC Grade 8 serrated flange nuts, four 0.250" × 0.88" × 2.25" square hole spacers, and two 7/16" fishwires.
The Curt 11386 is designed for use with ball mount #D-224.
Periodically check that all fasteners are tight and that all structural components are sound. The manual does not specify a retorque interval or other maintenance procedures.
The hitch is rated for 2,000 lbs trailer weight and 200 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower than the hitch rating.
Curt Manufacturing warrants the product to be free of defects in material and workmanship at the time of retail purchase by the original purchaser. If defective, Curt may repair or replace it at their option when returned prepaid with proof of purchase. Warranty is voided by alteration, misuse, or improper installation.

The Curt 56011 has two amperage ratings: signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
You will need: a ratchet, 10mm socket, Phillips screwdriver, and a panel trim removal tool. The manual also recommends having a test light or properly wired trailer available to test the harness after installation.
Yes. You must disconnect the negative battery terminal before beginning installation. This is the first step in the installation process and is essential for safety.
You must remove the rear access covers on both sides of the vehicle, all trunk floor coverings, and the rear scuff panel. These items must be removed to access the taillight wiring harness connectors.
Locate the vehicle's taillight wiring harness connectors inside the rear access panel. Separate the connectors from the taillight housing carefully, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors on the driver side, ensuring the connectors are fully inserted with locking tabs in place. Repeat on the passenger side using the harness end with the green wire.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. When not in use, the 4-flat connector should be rolled up and stored in a convenient, out-of-the-way location.
Drilling may be required for the ground wire connection. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
If you need to drill a grounding point for the white ground wire, drill a 3/32" pilot hole. The area should be free of rust, dirt and paint before securing the ring terminal and provided screw.
After routing the wiring harness, secure any loose wires with the provided cable ties. This helps prevent damage and keeps the installation neat.
After installation is complete and the battery is reconnected, test the wiring harness for proper function using a test light or by connecting a properly wired trailer. All steps must be followed to ensure the harness will function properly.
Reinstall all items you removed during installation, reconnect the negative battery terminal, and install the provided 4-flat dust cover to help prevent corrosion. Test the harness for proper function using a test light or a properly wired trailer.
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. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
Exceeding the product rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. The signal circuits are rated at 3.0 amps per side and tail/running circuits at 6.0 amps total.
