Complete CURT Class 1 1-1/4" trailer hitch and 5-flat wiring kit (with 4-way to 5-way adapter for surge brakes) engineered for the 2020 - 2026 Mazda CX-30. Vehicle-specific fit, plug-and-play installation, all hardware and instructions included.
This custom kit fits the following vehicles:
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 CX30 (see application info to verify fitment). 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 CX-30 (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.

The 20 - 24 Mazda CX-30 Curt 1-1/4" Class 1 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 11599 (Part #5W-CHW-2285) fits the following vehicles: 2020-2024 Mazda CX-30. Always verify your specific year, make, and model before ordering.
The 20 - 24 Mazda CX-30 Curt 1-1/4" Class 1 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 11599 (Part #5W-CHW-2285) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, CURT part number 11599 is designed for 2020-present Mazda CX-30 Crossover models. Verify your vehicle year and model match before purchasing.
The CURT 11599 is rated for a maximum trailer weight of 2,000 lbs. and a tongue weight of 200 lbs. when used as a weight-carrying hitch. You must not exceed your vehicle manufacturer's recommended towing capacity.
The manual does not provide the hitch weight specification.
You will need: a die grinder, ratchet, 3/4" socket, 6" socket extension, torque wrench, utility knife, and safety glasses. The manual rates this as an easy to moderate difficulty installation.
The kit includes: (4) 1/2" fishwires, (4) .250 x 1.00 x 3.00" square hole spacers (part CM-SP6), (4) 1/2"-13 UNC grade 8 carriage bolts 1-1/2" long (part 10-10287), and (4) 1/2"-13 UNC grade 8 serrated flange nuts (part 20-00062).
The manual does not specify whether battery disconnection is required. Contact CURT technical support at 877-287-8634 for clarification.
Two people may be required to ease installation. The manual recommends reading all instructions thoroughly before beginning and using proper tools to improve installation quality.
No, drilling is not required. However, you must use a die grinder to enlarge the third hole from the back of the vehicle on both sides of the frame rail to accommodate the supplied spacers and carriage bolt heads. Excess sealer should be removed with a utility knife if present.
No, fascia trimming is not required for this installation.
Yes, you must temporarily lower the exhaust by unhooking the (4) rubber isolators from the muffler. Support the exhaust so it is not damaged. After the hitch is installed and fasteners are torqued, raise the exhaust back into position and reinstall the (4) rubber isolators.
Fishwiring is a technique using the supplied 1/2" fishwires to thread carriage bolts and spacers through the frame holes before raising the hitch into position. You must fishwire (2) 1/2" carriage bolts and (2) square hole spacers into the first and second holes on both sides of the frame rail. This allows the bolts to be in place when you raise the hitch over the exhaust.
Carefully raise the hitch into position over the exhaust and onto the carriage bolts. Loosely install the supplied hex flange nuts. Push the hitch as far rearward on the vehicle as possible to give maximum clearance to the muffler and exhaust components.
All 1/2" fasteners must be torqued to 110 lb.-ft. This includes the carriage bolts and hex flange nuts.
Safety glasses must be worn at all times while installing this product.
All non-trailer (wheel-less) loads applied to this hitch must be supported by CURT part number 18050 stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. See the CURT catalog or visit www.curtmfg.com for further information.
You must never exceed your vehicle manufacturer's recommended towing capacity. The CURT 11599 is rated for 2,000 lbs. trailer weight and 200 lbs. tongue weight, but your vehicle's limits may be lower. Always follow your Mazda CX-30 owner's manual for towing specifications.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This is an ongoing maintenance requirement, not a one-time check.
The manual states you should periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound, but does not specify an exact interval. Regular inspection before towing is recommended.

Yes, the Curt 56450 powered converter is designed for Mazda 3 Sedan, Mazda 3 Hatchback, and Mazda CX-30. Installation procedures differ slightly between the Sedan and Hatchback versions, so follow the steps specific to your vehicle model. The manual provides separate instructions for each variant.
The Curt 56450 has the following electrical ratings: Signal circuits are rated at 5.0 amps per side, and Tail/Running circuits are rated at 7.5 amps total. The battery connection must be fuse-protected with a 15-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as exceeding this can cause loss of warranty, overheating and potential fire.
The following tools are required: ratchet, cutting tool, 10mm socket, wire crimper, socket extension, wire stripper, flathead screwdriver, trim panel removal tool, and electrical tape. Proper tools will improve the quality of installation and reduce the time required.
Yes, you must disconnect the negative battery terminal before beginning installation. Locate the vehicle battery (refer to your vehicle owner's manual if needed), disconnect the negative terminal, and fasten this wire down and away from the battery. Reconnect it only after all other installation steps are complete and the 12-volt power wire has been connected to the harness.
Pull back the felt side-wall of the hatch/trunk to locate the vehicle taillight wiring connectors. The connectors will be similar to those on the custom wiring product. For Mazda 3 Hatchback and CX-30, you may need to remove cover panels first. Separate the connectors from the taillight housing carefully, taking care not to damage the locking tabs.
Separate the vehicle's taillight connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring end with the yellow wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. This procedure is performed on both the driver side and passenger side of the vehicle.
The black converter box is the powered converter module that processes the trailer signals. Locate a flat spot inside the vehicle near the taillight and adhere the converter box using the provided double-sided tape. Ensure it is mounted securely in a location where it will not be disturbed.
The harness uses the following wire colors: Green for right turn signal, Red for brake, Yellow for left turn signal, and Brown for taillight. The custom wiring ends with yellow wire connect to the vehicle taillight connectors on both sides. The green wire is routed to the passenger side. The black power wire connects to the vehicle battery positive terminal, and the white ground wire connects to the vehicle body.
Route a 12 GA wire or larger from the vehicle battery to the converter, taking care to avoid pinch points and hot or rotating components. Use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges when passing through sheet metal. Connect the black power wire to the positive battery terminal using a ring terminal (provided). Secure the power wire to the vehicle chassis using the provided cable ties. Install the 15-amp fuse holder after all other steps are complete. Refer to the Power Converter Lead Instruction Sheet on page 6 for detailed routing guidance.
Attach the ring terminal of the white ground wire to the vehicle body using the screw provided. If necessary, drill a 3/32" hole to secure the ground connection. This ensures proper grounding of the converter system.
Use a 15-amp maximum fuse. The battery connection must be fuse-protected with a 15-amp fuse holder. Install the fuse after all other installation steps are complete. Exceeding this fuse rating can cause loss of warranty, overheating and potential fire.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
After the 12-volt power wire is connected to the harness, verify 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 converter is operating properly before regular use.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. This helps maintain proper function and prevents electrical issues over time.
Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. For specific lamp load ratings, check your vehicle owner's manual or contact the vehicle manufacturer. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Yes, for all Mazda 3 and CX-30 models, you must open the vehicle's hatch/trunk and remove the floor coverings from the spare tire and security cover (hatchback vehicles only) before beginning installation. This provides access to the taillight wiring connectors and interior trim components.
For Mazda 3 only, you must remove the skid plate. Using the trim panel removal tool, release the two push fasteners in the skid plate, then loosen and remove the skid plate itself. This provides access to the side panel fasteners and taillight wiring connectors. The Mazda CX-30 does not require skid plate removal.
On the driver side, use the trim panel removal tool to loosen the plastic trim at the top of the felt side-wall. Remove the single push fastener located right beneath the loosened trim piece. Under the skid plate, remove the two push fasteners securing the side panel to the vehicle. Repeat this process on the passenger side. For the passenger side, you may also need to remove a cover panel and pull back sound dampening material to expose the taillight harness.
On both the driver and passenger sides, under the skid plate, remove the push fastener securing the side panel to the vehicle. This is a simpler process than the Hatchback version. Once the side panels are removed, pull back the felt side-wall to locate the taillight wiring connectors.
On the driver side, use the trim panel removal tool to loosen the plastic trim at the top of the felt side-wall. Remove the two push fasteners located right beneath the loosened trim piece. Under the skid plate, remove the two push fasteners securing the side panel to the vehicle. Using a flathead screwdriver, open the cargo tie-down fastener cover. Using a 10mm socket, remove the tie-down on the side-wall and any in the rear trunk area. Repeat this entire process on the passenger side. For the passenger side, you will also need to remove three push fasteners (one on the floor and two at the top) securing a cover panel to access the taillight connectors.
The installation is rated as 'Easy' in difficulty level, based on time and effort involved. However, difficulty may vary depending on the installer's level of expertise, the condition of the vehicle, and having proper tools and equipment. The manual provides detailed step-by-step instructions for all three vehicle models (Mazda 3 Sedan, Mazda 3 Hatchback, and Mazda CX-30).
Drilling may be required only for the ground wire connection. You may need to drill a 3/32" hole to attach the white ground wire ring terminal to the vehicle body using the provided screw. However, if a suitable existing hole is available, drilling is not necessary. No other drilling is required for the main harness installation.
No permanent modifications are required. The converter box is mounted using provided double-sided tape, which is removable. The wiring is routed through existing interior spaces and connected to factory taillight connectors without cutting or permanently altering vehicle components. The only potential permanent modification is drilling a 3/32" hole for the ground wire if no existing hole is suitable, but this is a small, non-structural hole.
The Curt 56450 is designed for use only on 12-volt negative ground systems. Verify that your Mazda 3 or CX-30 has a 12-volt negative ground electrical system before installation. If you are unsure, consult your vehicle owner's manual.
Yes, the Curt 56450 is designed for Mazda 3 (Sedan and Hatchback) and Mazda CX-30. Installation procedures differ slightly by model, so follow the steps specific to your vehicle.
Use a 15-amp maximum fuse for the battery connection. Install the fuse after all other steps are complete.
Signal circuits: 5.0 amps per side. Tail/Running circuits: 7.5 amps total. Do not exceed the product rating or your vehicle's lamp load rating, whichever is lower.
