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 CX-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 Mazda CX3 and MX-5 Miata (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 Curt 56300 is designed for Mazda CX-3, Mazda 6, and Mazda MX-5 models. Installation procedures vary slightly by model: CX-3 and Mazda 6 require removal of floor coverings and cargo hold-downs from the trunk, while MX-5 requires removal of floor coverings and rear trunk panel. Consult the model-specific steps in the installation manual for your vehicle.
The Curt 56300 is a trailer wiring harness with a powered converter module. It connects your vehicle's taillight wiring to a 4-flat trailer connector, allowing you to tow a trailer with integrated lighting. The converter processes your vehicle's turn signal, brake, and taillight circuits to power the trailer lights.
Yes. The converter system is designed only for 12-volt negative ground systems. If your vehicle uses a different electrical system configuration, this product is not compatible.
Required tools are: ratchet, panel trim removal tool, 10mm socket, cutting tool, socket extension, wire crimper, flathead screwdriver, and wire stripper. Proper tools will improve installation quality and reduce installation time.
Yes. You must locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery while completing the installation process. Reconnect it only after all other installation steps are complete.
Drilling may be required for the ground wire connection. You must locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you will need to drill a 3/32" pilot hole for the provided ground screw. The area must be free of rust, dirt, and paint before securing the white ground wire with the ring terminal.
Drill a 3/32" pilot hole if an existing screw with nut is not available at the grounding point. The area must be free of rust, dirt, and paint before installing the provided screw with the white ground wire ring terminal.
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. The fuse holder should be installed after all other installation steps are complete.
Signal circuits (turn signals): 3.0 amps per side. Tail/running circuits: 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. For additional information, check your vehicle owner's manual or contact the vehicle manufacturer.
Use 12 GA (12-gauge) wire or larger for the power wire routing from the vehicle battery to the converter. Route the 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.
The harness wire colors are: Green (right turn signal), Red (brake), Yellow (left turn signal), and Brown (taillight). The custom wiring harness has a yellow wire end for the driver side and a green wire end for the passenger side. The black power wire connects to the vehicle battery positive terminal, and the white ground wire connects to the vehicle body.
Mount the black converter box using the provided double-sided tape on a flat spot inside the vehicle near the taillight. The converter should be positioned after the custom wiring harness is inserted between the separated taillight connectors.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route the 4-flat to the center of the vehicle. Secure any loose wires with the provided cable ties.
After connecting the 12-volt power wire 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. This confirms all circuits are working properly before regular use.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Install the provided 4-flat dust cover to help prevent corrosion of the connector.
Before drilling to create the ground wire pilot hole, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area where you drill must be free of rust, dirt, and paint.
