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 Ram ProMaster 1500, 2500, and 3500 (standard body only for 2500 and 3500 models). See application info to verify vehicle compatibility. It provides a weight carrying capacity of 6,000 lbs. GTW and 750 lbs. TW. It is also compatible with a weight distribution hitch for level towing and a rating of 7,500 lbs. WD and 750 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 Ram ProMaster 1500, 2500 and 3500 (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.

When used as a weight distribution hitch, it supports 7,500 lbs trailer weight and 750 lbs tongue weight. However, you must never exceed your vehicle manufacturer's recommended towing capacity.
The hitch weight is 40 lbs.
You will need: a ratchet, torque wrench, 3/4" socket, 7/8" socket, and a small screwdriver. Safety glasses should be worn at all times during installation.
No, drilling is not required. The hitch uses existing frame rail mounting holes that are accessed by removing rubber plugs.
Two people may be required to ease installation. If you are hesitant to undertake this task on your own, contact an authorized CURT installer for additional assistance.
Professional installation takes approximately 40 minutes. Novice (DIY) installation takes approximately 60 minutes.
Remove the rearwardmost rubber plugs in the frame rails and any foil covering the mounting holes. Return the rubber plugs to the vehicle owner. Then fishwire the 9/16" x 2 1/2" carriage bolt and CM-SP70 spacer on the side with the recovery loop, and the 9/16" x 2" carriage bolt and CM-SP70 spacer into the holes that had the rubber plugs.
Raise the hitch on the driver side with the forwardmost tab over the leaf spring and angle the hitch to get the forwardmost tab on the passenger side over the leaf spring. Once in position, lift the driver side bracket up to the frame rail and slide the hitch over the rear bumper stud and the inner frame stud. Then push the hitch toward the driver side and raise the passenger side bracket up to the frame.
The 13207-SP spacer (.625 x 2.00) is slid between the hitch and the frame on the passenger side with the bolt passing through it. It is loosely secured with a 9/16" hex flange nut during assembly.
The two 1/2" handle nuts are slid into the grooved section of the frame over the forwardmost tabs and secured with 1/2" x 1 1/2" hex bolts and conical tooth washers.
Torque all 9/16" fasteners to 150 lb-ft and all 1/2" fasteners to 110 lb-ft.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. This should be done regularly to maintain safe operation.
Never exceed your vehicle manufacturer's recommended towing capacity. While the 13207 is rated for 6,000 lbs (weight carrying) or 7,500 lbs (weight distribution) trailer weight, your RAM ProMaster's manufacturer specifications may be lower and must be followed.

Part 56478 is designed for SUVs and Vans. The manual does not list specific vehicle makes, models or years. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your vehicle before purchasing.
The 56478 is a wiring converter for SUVs and Vans that integrates with the vehicle's taillight wiring system. It includes a converter box, custom wiring harness with color-coded wires (yellow for left turn, green for right turn, red for brake, brown for taillight), a power lead that connects to the vehicle battery, and a 4-flat connector for external use. The manual does not specify whether it is for trailer lighting, towing, or another application.
Yes. The converter system is designed only for 12-volt negative ground electrical systems. Do not use on any other system type.
Required tools are: ratchet, 10 mm socket, Phillips screwdriver, flathead screwdriver, panel trim removal tool, wire stripper, wire crimper, electrical tape, and cutting tool. Proper tools will improve installation quality and reduce time required.
Yes. You must disconnect the negative battery terminal before beginning installation. The battery is located under the driver-side floor panel, secured by six fasteners. Remove the floor panel to access it. Reconnect the negative battery terminal after all other installation steps are complete and before installing the fuse.
Mount the black converter box on the upper corner inside the rear cargo door frame on the driver side using the provided double-sided tape. The area should be flat and clean. Ensure the area is free of rust, dirt and paint before adhering.
Open the rear cargo doors. On the driver side, remove seven Phillips screws from the plastic cover to locate the vehicle taillight wiring harness connectors. 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, ensuring they are fully inserted with locking tabs in place. Repeat this process on the passenger side using the custom wiring harness end with the green wire.
Route the custom wiring harness end with the green wire to the passenger side through the opening that runs up and over the rear cargo doors. This connects the passenger-side taillight connector to the converter system.
Drilling may be required for the ground wire connection. Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be behind or under the surface to avoid personal injury or property damage.
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. The area must be free of rust, dirt and paint. Remove the nut from the existing screw or the provided screw, install the white ground wire ring terminal, and replace the nut to secure it.
Route the black power wire from the vehicle battery as follows: start at the wiring harness converter box, along the top of the driver-side cargo area and down along the frame located behind the driver seat. Continue from the cargo area along the bottom of the driver-side seat frame and route the power wire under the floor panel section to the battery. Use the provided cable ties to secure any loose wires. 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. Avoid pinch points and hot or rotating components.
Remove the Phillips screws from the plastic seat belt trim panel and the trim around the driver-side seat and floor. Remove all plastic trim panels to allow routing of the power wire from the converter box to the battery. These panels are reinstalled after the power wire is routed.
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. Do not exceed this rating, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
Signal circuits are rated at 7.5 amps per side. Tail/running circuits are rated at 7.5 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Yellow = Left turn; Green = Right turn; Red = Brake; Brown = Taillight. The converter also includes a white ground wire and a black power wire that connects to the vehicle battery positive terminal.
Use 12-gauge wire or larger for the power connection from the converter to the vehicle battery. The manual specifies '12 GA wire or larger' for the power lead.
When in use, route the 4-flat connector to the center of the vehicle and out of the cargo area. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Install the provided 4-flat dust cover to help prevent corrosion.
Disconnect the negative battery terminal before beginning installation. Do not lay tools across the positive battery terminal (typically noted with red covers or a red '+' symbol), as this can cause a ground short, resulting in sparks and/or electrical shocks. Use a ring terminal for the battery connection. Disconnect the negative battery cable before wiring the power wire to the battery.
Before drilling, check for miscellaneous items that may be behind or under the surface to avoid personal injury or property damage. This is especially important when drilling the 3/32" pilot hole for the ground wire connection.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All installation steps must be followed to ensure the product functions properly.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. No other maintenance intervals are specified in the manual.
The installation difficulty is rated as Easy. Installation difficulty levels are based on time and effort involved and may vary depending on the installer's level of expertise, condition of the vehicle, and proper tools and equipment.
Open the rear cargo doors. On each side (driver and passenger), remove seven Phillips screws from the plastic cover to locate the vehicle taillight wiring harness connectors. These covers provide access to the connectors you need to separate and integrate with the custom wiring harness.
