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 Honda Pilot and Acura MDX (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 6,000 lbs. GTW and 900 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 8,000 lbs. WD and 900 lbs. WDTW. 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.
CURT custom wiring connectors and harnesses are the easiest way to outfit your vehicle with a trailer wiring connection for towing. Each one is custom-fitted to work with a specific make and model. This particular 7-way RV blade socket is designed to be a custom wiring option for certain years of the Honda Pilot and Passport (see application info to verify fitment). It provides a universal trailer connection for the tail lights, brake lights, reverse lights, turn signals, electronic trailer brakes and auxiliary power. 7prong taillight wiring can be used as a replacement or new wiring and is typically used for towing fifth wheel and gooseneck trailers. This 7 way female outlet comes with all necessary hardware to establish a solid connection, as well as a dust cover to keep the connector socket clean when not in use. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this factory tow package socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Instead of cutting, splicing and soldering into your vehicle's wiring system, the custom wiring connector uses a single OEM compatible plug and instantly provides a standard vehicle-to-trailer hitch wiring connection. To ensure long-lasting reliability, all CURT custom tconnector wiring is thoroughly tested for optimal functionality.

Yes, the 16 - 22 Honda Pilot Curt 2", Class 3 Trailer Tow Hitch + 7-way Wiring Kit 13146 (Part #CHW-1789) is designed to fit the 2016-2022 Honda Pilot.
The 16 - 22 Honda Pilot Curt 2", Class 3 Trailer Tow Hitch + 7-way Wiring Kit 13146 (Part #CHW-1789) fits the following vehicles: 2016-2022 Honda Pilot. Always verify your specific year, make, and model before ordering.
The 16 - 22 Honda Pilot Curt 2", Class 3 Trailer Tow Hitch + 7-way Wiring Kit 13146 (Part #CHW-1789) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 13146 has a gross trailer weight (GTW) capacity of 6,000 lbs and a tongue weight (TW) capacity of 900 lbs. For weight distribution towing, the weight distribution (WD) capacity is 8,000 lbs with a WD tongue weight (WDTW) of 900 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
No. The CURT 13146 installation requires no drilling. The hitch mounts to existing weldnuts on the vehicle frame.
You will need: a ratchet, a torque wrench, a 22mm socket, a 6" socket extension, and a wire pipe brush. The wire brush is used to clean debris from the weldnuts in the frame. A tools reference guide is available at curtmfg.com/trailer-hitch-installation.
The kit includes 6 hex bolts (M14-1.50 x 40mm, CL 10.9) and 6 conical-toothed washers (9/16"). These fasteners mount the hitch to the vehicle frame weldnuts.
Yes. Step 1 of the installation requires you to lower the spare tire from inside the vehicle using the tools stored in the storage compartment. After the hitch is secured, you will raise the spare tire back into place following the same instructions.
Yes. Weldnut cleaning may be required. To remove debris from the weldnuts in the frame, spray lubricant or compressed air into the hole. For heavy debris, use a wire brush. Take care not to damage the threads. The manual notes this step in the assembly diagram and Step 2 of the installation.
All M14 bolts must be torqued to 139 lb-ft. Use a torque wrench to ensure proper tightening during installation.
The conical-toothed washers should be placed with the toothed side facing the hitch side plate. The assembly diagram on page 2 shows the correct orientation: the hex bolt passes through the washer, and the washer sits between the bolt head and the hitch side plate.
Safety glasses should be worn at all times while installing this product. Additionally, never exceed your 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. This helps prevent damage to the product and vehicle.
The manual does not specify vehicle makes, models, or years. Contact CURT product support at 877.287.8634 or visit curtmfg.com to confirm fitment for your specific vehicle.
No. The installation requires no drilling. The hitch mounts to existing weldnuts on the vehicle frame.

Yes, CURT part 56421 is designed for both Honda Pilot and Honda Passport SUVs. However, the installation procedure differs between the two vehicles. Honda Pilot installation follows steps 2A through 10A, while Honda Passport installation follows steps 2B through 7B. Both vehicles then proceed to the common steps 11 onwards.
The product has the following electrical ratings: signal circuits are rated at 3.0-amps per side, and tail/running circuits are rated at 6.0-amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Required tools are: 8mm socket, ratchet, socket extension, cutting tool, panel trim removal tool, large Phillips screwdriver, small flat head screwdriver, and impact screwdriver with large Phillips head. Proper tools will improve the quality of installation and reduce the time required.
Yes. Step 1 requires you to locate the vehicle battery using the owner's manual, then disconnect the negative battery terminal. Fasten this wire down and away from the battery when completing the installation. The powered converter lead instruction sheet also specifies: disconnect the negative battery cable before wiring the power wire.
The installation difficulty level is rated as Moderate. The manual recommends reading all instructions thoroughly before beginning and following all steps to ensure the product functions properly.
Drilling may be required for the ground connection. Step 13 instructs you to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw if no existing point is available. The area should be free of rust, dirt, and paint. A caution warns to check for miscellaneous items hidden behind or under any surface before drilling to avoid damage and personal injury.
Three fuses are required: one 10-amp (red) inline fuse installed in the fuse holder on the factory harness during the initial wiring steps, and two additional fuses installed in the engine compartment fuse panel. In Step 14, install two 20-amp (yellow) fuses in locations three and eleven, and one 30-amp (pink) fuse in location two of the fuse panel next to the brake fluid reservoir. The battery connection must be fuse-protected with a 10-amp max.
The power wire is 12 GA (12 gauge) or larger. This wire routes from the vehicle battery to the converter system. The powered converter lead instruction sheet specifies that the 12 GA wire should be routed to the vehicle battery location, taking care to avoid pinch points and hot or rotating components.
The converter output wires are: Green for right turn, Red for brake, Yellow for left turn, and Brown for taillight. These wires connect to the trailer lighting system.
The black converter box is mounted using the provided double-sided tape. Step 13 instructs you to locate a flat spot on the floor board of the vehicle and adhere the converter box using this tape. The converter should be positioned near the grounding point.
Step 12 instructs you to use a cutting tool to carefully cut the grommet, creating a large enough opening for the custom wiring harness to pass through while allowing the grommet to be pushed back into place in the vehicle body. After routing the harness, use the provided tube of silicone to seal around the custom wiring harness.
If the backup sensor housing is already connected to a harness, you will need to disconnect it. After installing the custom wiring harness to the vehicle wiring harness, reconnect the backup sensor to the single wire connector on the custom wiring harness. This allows the backup sensor to continue functioning. Make sure all connectors are fully inserted with locking tabs in place.
Routing varies by vehicle. For Honda Pilot: the white connector end routes between the vehicle floor pan and the driver-side wall, in front of the jack mount and behind the access panel (Step 8A). The round housing feeds down through the grommet under the third row seat, with the USCAR plug fitting through the oval opening sideways (Step 10A). For Honda Passport: the harness runs under the carpet and through the grommet hole, with the USCAR plug fitting through the oval opening sideways (Step 7B). For both vehicles, the wiring routes in the center of the vehicle (above the spare tire on the Pilot) and is secured with zip ties as needed before plugging into the 7-way socket connector (Step 11).
The converter system is designed for use only on 12-volt negative ground systems. The powered converter lead instruction sheet explicitly states: "This converter system is to be used only on 12 volt negative ground systems."
When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges. The powered converter lead instruction sheet warns: "When passing the power wire through sheet metal, use an existing grommet, add a grommet or use silicone to protect the power wire from sharp edges."
Do not lay tools across the positive terminal (typically labeled with red covers or a red "+" symbol). This can cause a ground to short, causing sparks and/or electrical shocks. Additionally, disconnect the negative battery cable before wiring the power wire to avoid accidental short circuits.
After completing all installation steps and reconnecting the negative battery terminal, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. The manual states: "Once the 12 volt power wire is connected 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."
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 safety of the wiring harness.
If lights do not function, perform the following checks: (1) Verify the inline fuse is good. (2) Check the grounding location using a test light by attaching the clip end to the ground location and using the probe end on the power wire from the battery. (3) Make sure the surface around the ring terminal is raw or bare metal, free of rust, dirt, and paint. Poor grounding is a common cause of non-functioning lights.
Yes, CURT 56421 is designed for both Honda Pilot and Honda Passport. Installation procedures differ between the two vehicles, but both are fully supported.
You need: 8mm socket, ratchet, socket extension, cutting tool, panel trim removal tool, large Phillips screwdriver, small flat head screwdriver, and impact screwdriver with large Phillips head.
Yes, disconnect the negative battery terminal before beginning installation. Fasten the wire down and away from the battery.
Drilling may be required for the ground connection. You may need to drill a 3/32" pilot hole for the ground screw if no existing mounting point is available. Check for hidden items before drilling.
Install one 10-amp (red) inline fuse in the factory harness, then install two 20-amp (yellow) fuses and one 30-amp (pink) fuse in the engine compartment fuse panel locations 3, 11, and 2 respectively.
Signal circuits: 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.
CURT 56421 is designed for 12-volt negative ground systems only.
Test with a test light, 4-flat tester, or a functioning trailer after reconnecting the battery and completing all installation steps.
Possible causes include: (1) a faulty inline fuse, (2) poor grounding connection, or (3) corroded or painted surface around the ring terminal. Check the inline fuse first. Then use a test light to verify the grounding location by attaching the clip end to the ground location and the probe end to the power wire from the battery. Ensure the surface around the ring terminal is raw or bare metal, free of rust, dirt, and paint.
