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 Acura MDX and Honda Pilot (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.
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 Acura MDX (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.

Safety glasses must be worn at all times during installation. Never exceed your vehicle manufacturer's recommended towing capacity. Proper tools will improve installation quality and reduce installation time. Before beginning, read all instructions thoroughly.
After installation, inspect the hitch and spare tire to ensure there is adequate clearance between them. If additional clearance is needed, push the tire forward while raising it. Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. The manual does not specify the exact inspection interval; consult the manufacturer for detailed maintenance recommendations.
If additional clearance is needed between the hitch and tire, push the tire forward while raising it. If clearance is still insufficient, consult the manufacturer or a professional installer to determine if the hitch position can be adjusted or if a different mounting configuration is required.
Debris or corrosion in the weldnuts may prevent proper bolt seating. Clean the weldnuts thoroughly using lubricant spray or compressed air, and use a wire brush for heavy debris. Take care not to damage the threads. If the bolts still will not tighten, the weldnuts may be damaged and require professional repair.
Part 56547 is designed for SUVs and vans with 12-volt negative ground electrical systems. The wiring location guide shows connection points for these vehicle types. Check your vehicle's owner's manual to confirm it has a 12-volt negative ground system. If your vehicle is not an SUV or van, this product is not compatible.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. 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.
You will need a small flathead screwdriver and a panel trim removal tool. These are the only tools listed as required for installation.
Yes. Disconnect the negative battery terminal in the engine compartment on the driver side before beginning installation. Fasten this wire down and away from the battery while completing the installation. Reconnect it only after all other steps are complete and you have tested the harness.
The white electrical housing connector block is located on the wall by the rear cargo hatch. Remove the dust cover from the uncoupled housing before installing the custom harness to this connector.
The rear fuse panel is located beneath the rear, driver-side seat. Open the panel cover using a small flathead screwdriver. You will find a bagged kit inside the custom harness package containing one 10-amp red fuse and one 20-amp yellow fuse.
Install the red 10-amp fuse in location 15 labeled "Trailer Hazard Light." Install the yellow 20-amp fuse in location 26 labeled "Trailer Charge."
Not necessarily. First, locate an existing screw or bolt in the vehicle frame to use as a grounding point. If no suitable existing fastener is available, you may drill a 3/32" pilot hole. Before drilling, ensure the area is free from rust, dirt, and paint—use an abrasive pad or paper to clean it. Always check for miscellaneous items hidden behind or under any surface before drilling to avoid damage and personal injury.
The white ground wire has a ring terminal. Secure it to an existing fastener in the vehicle frame, or to a new fastener if you drill a 3/32" pilot hole. Use the provided ground screw if drilling a new hole. Ensure the area is free from rust, dirt, and paint before securing.
Use 12 GA wire or larger for the power lead. Route this wire to the vehicle battery location, 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.
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 trailer connector uses the following wire colors: Green for right turn, Red for brake, Yellow for left turn, and Brown for taillight.
When in use, route the 4-flat with the center of the vehicle and out of the hatch to the trailer, staying clear of the hatch's latching mechanism. When not in use, roll up and store in a convenient, out-of-the-way location. Install the 4-flat dust cover to help prevent corrosion.
Test the harness by connecting the 4-flat to a test light, 4-flat tester, or a functioning trailer. This should be done before reinstalling all items removed during installation and before reconnecting the negative battery terminal.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Secure any loose wires with the provided cable ties.
Do not lay tools across the positive battery terminal (typically noted with red covers or a red '+' symbol). This can cause a ground short, resulting in sparks and/or electrical shocks. Always disconnect the negative battery terminal before wiring the power wire.
No. The 56547 is designed only for 12-volt negative ground electrical systems. It is not compatible with 24-volt systems or positive ground systems.
Open the vehicle's rear hatch and remove all trunk floor coverings to access the lower storage area. Using the trim panel tool, loosen the threshold and remove it straight up.
The 56547 is designed for SUVs and vans with 12-volt negative ground electrical systems. Confirm your vehicle type and electrical system in your owner's manual.
Yes, disconnect the negative battery terminal before starting installation and reconnect it only after testing the harness.
Drilling is not required if an existing screw or bolt is available for the ground wire. If not, you may drill a 3/32" pilot hole. Always check for hidden items before drilling.
The battery connection must use a 10-amp maximum fuse. Exceeding this can cause loss of warranty, overheating, and potential fire.
Signal circuits: 3.0 amps per side. Tail and running circuits: 6.0 amps total. Do not exceed the product rating or your vehicle's lamp load rating.
Connect the 4-flat to a test light, 4-flat tester, or functioning trailer to verify proper operation before reinstalling removed items.
First, verify that the negative battery terminal was reconnected after testing. Check that both fuses are properly installed in the correct locations: 10-amp red fuse in location 15 (Trailer Hazard Light) and 20-amp yellow fuse in location 26 (Trailer Charge). Inspect all wire connections at the white electrical housing connector block and the ground wire connection to ensure they are secure and free of corrosion. Test the harness again using a test light, 4-flat tester, or functioning trailer. If the issue persists, inspect all wires for visible damage or loose connections.
