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 Mazda CX-50 (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 525 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 Mazda CX-5 and CX-50 (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 Curt 56487 is a powered converter that converts a vehicle's taillight signals to a 4-flat trailer connector. It allows you to connect a trailer with functioning lights to your SUV or van, so the trailer lights operate in sync with your vehicle's taillights, turn signals and brake lights.
The Curt 56487 is designed for SUVs and vans with 12-volt negative ground electrical systems. The manual does not specify which vehicle models or years are compatible. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make and model to confirm compatibility.
No. The Curt 56487 is designed only for 12-volt negative ground systems. It cannot be used on 24-volt systems or positive ground systems.
Required tools are: ratchet, 10mm socket, socket extension, panel trim removal tool, Phillips screwdriver, flathead screwdriver, cutting tool, wire stripper, wire crimper, and electrical tape. You will also need an abrasive pad or paper to remove rust and paint from the grounding point.
The kit includes a custom wiring harness with yellow, green, white and black wires; a black converter box; a ground screw; a ring terminal; double-sided tape for mounting the converter box; cable ties; a 4-flat connector; a 4-flat dust cover; and a fuse holder with 10-amp fuse.
Yes. Step 1 requires you to locate the vehicle battery and disconnect the negative battery terminal before beginning installation. Fasten this wire down and away from the battery while completing the installation process.
You must remove the rear scuff panel, and on both the driver and passenger sides, remove the interior side trim panels. These panels provide access to the taillight wiring harness connectors where the custom harness is inserted.
After removing the interior side trim panels, locate the vehicle's taillight wiring harness connectors behind the trim. 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 on the driver side, ensuring the connectors are fully inserted with locking tabs in place. Repeat on the passenger side using the green wire.
Locate a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Adhere the black converter box to this surface using the provided double-sided tape. The manual indicates wiring locations S3 and S4 (behind driver and passenger side rear access panels) are used for this product.
You may not need to drill if you can secure the white ground wire with the ring terminal to an existing screw or bolt in the vehicle frame. If no suitable existing fastener is available, drill a 3/32" pilot hole in a clean area free from rust, dirt and paint (use an abrasive pad or paper to prepare the surface). Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Drill a 3/32" pilot hole if an existing fastener is not available for grounding the white ground wire with its ring terminal.
Signal circuits (turn signals): 3.0 amps per side. Tail/Running circuits: 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Yellow wire = Left turn signal; Green wire = Right turn signal; Red wire = Brake light; Brown wire = Taillight/Running light. The white wire is the ground wire, and the black wire is the power wire that connects to the vehicle battery.
Route the black 12-gauge power wire from the vehicle battery to the converter, taking care 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. Install the 10-amp fuse in the fuse holder after all other steps are complete.
Use a 10-amp fuse maximum. The battery connection must be fuse-protected with a 10-amp max fuse. Install the fuse after all other installation steps are complete.
Use a ring terminal for the battery connection. The white ground wire also uses a ring terminal, which is secured to the vehicle body with the provided screw or a drilled 3/32" hole.
The power wire should be 12-gauge or larger.
Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. 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. Additionally, before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
After installation, verify that the harness is functioning by attaching the 4-flat connector to any trailer with functioning lights. The taillights on the vehicle to be towed should function along with the taillights on the vehicle that is powering them. Test using a test light or a properly wired trailer.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
Route the green wire over and down behind the interior side panel and out to the passenger side behind the removed scuff panel. Zip tie as needed along the rear bumper.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route the 4-flat to the center of the vehicle and out of the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
The Curt 56487 is designed for SUVs and vans with 12-volt negative ground electrical systems. Confirm your vehicle's compatibility with Curt Manufacturing or a fitment database before purchasing.
Drilling may be required only if no existing fastener is available for the ground wire. If needed, drill a 3/32" pilot hole. Always check for hidden items behind or under surfaces before drilling.
Use a 10-amp fuse maximum. The battery connection must be fuse-protected, and the fuse should be installed after all other installation steps are complete.
Use 12-gauge wire or larger for the power wire connecting to the vehicle battery.
Do not exceed the product rating or tow vehicle lamp load rating. The battery connection must be fuse-protected with a 10-amp maximum. Exceeding the rating can cause loss of warranty, overheating and potential fire.
First, verify that the custom harness is functioning by attaching the 4-flat connector to a trailer with functioning lights. The taillights on the vehicle to be towed should function along with the taillights on the vehicle powering them. If they do not, check that: (1) the custom harness connectors are fully inserted with locking tabs in place at both the driver and passenger side taillight connections; (2) the converter box is properly mounted and not damaged; (3) the ground wire ring terminal is securely attached to the vehicle frame; (4) the black power wire is properly connected to the positive battery terminal with a ring terminal; (5) the 10-amp fuse is installed and not blown; and (6) all wire connections are secure and show no visible damage.
The CURT 13630 has a gross trailer weight (GTW) capacity of 3,500 lbs and a tongue weight (TW) capacity of 525 lbs.
The kit includes one trailer hitch assembly, four M12-1.25 x 45mm hex bolts, and four 1/2" conical-toothed washers. The hitch panel removed from the bumper during installation should be returned to the vehicle owner.
Required tools are: ratchet, torque wrench, 19mm socket, flathead screwdriver, cut-off wheel, Phillips screwdriver, and tape. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
The installation is rated as Easy. Installation difficulty levels are based on time and effort involved and may vary depending on installer expertise, vehicle condition, and proper tools and equipment.
Before installation, read all instructions thoroughly. The installation requires hitch panel removal and underbody support trimming. Proper tools will improve installation quality and reduce time required.
Yes. The center of the bumper support must be trimmed using a cut-off wheel, aligned with the slot for the hitch panel. This is a permanent modification to the vehicle's bumper support.
Remove two screws from the center of the bumper to release the hitch panel. Return the panel and screws to the vehicle owner.
Use tape to mark the bumper support in line with the slot for the hitch panel. This mark guides where to trim the center of the bumper support using a cut-off wheel.
Using a flathead screwdriver or paint scraper, remove the tape from the outside of the frame rails covering the weldnuts in the frame. If weldnuts contain debris, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush, taking care not to damage threads.
Raise the hitch into position and secure it with the supplied M12 bolts and conical-toothed washers. Depending on the model, the forward-most mounting holes may vary; use the slot that aligns with the weldnut in the frame.
All M12 hardware must be torqued to 86 ft-lbs.
The mounting bolts are M12-1.25 x 45mm hex bolts. Four bolts are supplied with the hitch.
Four 1/2" conical-toothed washers are supplied to be used with the M12 bolts during hitch installation. They are positioned between the bolt and the hitch side plate, as shown in the assembly diagram.
Safety glasses should be worn at all times while installing this product. Never exceed the vehicle manufacturer's recommended towing capacity when using the hitch.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure.
To help prevent damage to the product or vehicle, the specified torque specifications must be followed when securing hardware during installation. All M12 hardware must be torqued to 86 ft-lbs to ensure proper fastening.
