All Hardware and Installation Instructions Included!
This CURT hitch is an accessory mount, ideal for adding a cargo carrier or bike rack onto your vehicle. It is made for vehicle-specific mounting. This particular kit fits certain years of the Subaru Solterra and Toyota BZ4X (see application info to verify vehicle compatibility). It provides a tongue weight capacity of 200 lbs. (NOTE: Never exceed the lowest-rated towing component). This hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety.
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 Subaru Solterra and Toyota BZ4X (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 56550 is a custom wiring harness with a powered converter module for SUVs and vans. It converts vehicle taillight signals and provides power for trailer lighting. The system includes a converter module, wiring harness with color-coded wires (green for right turn, yellow for left turn, red for brake, brown for taillight), and a 4-flat connector for trailer connection.
The Curt 56550 is designed for SUVs and vans. The manual does not list specific vehicle models or years. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your vehicle before purchasing.
Yes. The converter system is designed only for 12-volt negative ground electrical systems. If your vehicle uses a different electrical system, this product is not compatible.
Required tools are: ratchet, ratchet extension, 10mm socket, flathead screwdriver, wire cutter, wire stripper, panel trim removal tool, and wire crimper. The manual rates installation difficulty as 'Difficult' and notes that proper tools will improve installation quality and reduce time required.
The kit includes: a powered converter module, color-coded wiring harness (green, yellow, red, brown wires), white ground wire with ring terminal, black power wire, 2-sided tape for module mounting, cable ties for securing wires, a ground screw, a fuse holder with 10-amp max fuse, and a 4-flat connector. The manual does not specify quantities of cable ties or other consumables.
Yes. Step 1 requires you to locate the vehicle battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation. Reconnect it only after all other steps are complete and the fuse is installed.
Open the hatch and remove floor coverings and cargo trays. Remove the retaining clip holding the molded foam jack storage case. Using a trim panel tool, pull up and remove the rear threshold plate. On the driver side, use a 10mm socket to remove the cargo tie down, use a panel trim tool to remove the upper clip, and loosen the side wall trim to access the body and taillight wiring connectors.
Locate the vehicle's taillight wiring connectors (they will be similar to those on the custom harness). Carefully separate the connectors from the taillight housing without damaging the locking tabs. Locate the custom harness end with the yellow wire and attach the connectors between the taillight harness and the factory connectors. Repeat this process on the passenger side with the connector for the green wire.
Route the housing with the green wire along the rear of the vehicle to the driver side, securing as needed with cable ties. The manual identifies wiring locations S3 and S4 (behind driver and passenger side rear access panels) as the primary routing locations. When the 4-flat connector is in use, route it to 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 inside the trunk.
Locate a mounting spot for the module and secure it to the vehicle using the supplied 2-sided tape and/or zip ties. The manual does not specify an exact location, so choose a spot that is accessible, protected from moisture, and does not interfere with vehicle operation or hatch closure.
Not necessarily. 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-inch pilot hole. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it.
If an existing fastener is not available, drill a 3/32-inch pilot hole for the ground screw. Before drilling, ensure the area is free from rust, dirt, and paint by using an abrasive pad or paper. Always check for hidden items behind or under any surface before drilling to avoid damage and personal injury.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone to protect the power wire from sharp edges. This prevents damage to the wire insulation and potential electrical hazards.
Signal circuits are rated at 3.0 amps per side. This applies to the left turn and right turn signals.
Tail and running light circuits are rated at 6.0 amps total.
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. Install the fuse after all other installation steps are complete.
The power wire is 12 gauge (12 GA) or larger. Route this wire from the vehicle battery as shown on the provided Powered Converter Lead Instruction Sheet, taking care to avoid pinch points and hot or rotating components.
The color-coded wires are: Green = Right turn signal, Yellow = Left turn signal, Red = Brake signal, Brown = Taillight. The white wire is the ground wire, and the black wire is the power wire that connects to the positive battery terminal.
Route the 12-gauge black power wire from the converter to the positive battery terminal (+). Use a ring terminal for the battery connection. The wire must pass through a fuse holder with a 10-amp maximum fuse before connecting to the battery. Disconnect the negative battery terminal before wiring the power wire, and reconnect it only after all other steps are complete and the fuse is installed.
Attach the ring terminal of the white ground wire to the vehicle body using the screw provided. If no existing fastener is available, drill a 3/32-inch pilot hole. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it before securing the ground wire.
If using the converter as a powered module for a two-wire system, the red brake wire must be grounded.
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 leading to sparks and/or electrical shocks. Additionally, do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Route the 12-gauge power wire to the vehicle battery location, taking care to avoid pinch points and hot or rotating components. Secure the power wire to the vehicle chassis using the provided cable ties. When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone to protect the wire from sharp edges.
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. The manual requires testing before considering the installation complete.
After testing the harness for proper function, reinstall all items removed during installation (floor coverings, cargo trays, retaining clips, threshold plate, cargo tie down, trim panels). If the negative battery terminal was disconnected at the beginning, reconnect it. Secure any loose wires with the provided cable ties. When the 4-flat connector is not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk.
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 prevent electrical hazards.
Yes, the Curt 56550 is designed for SUVs and vans. Confirm your specific vehicle model and year are compatible before purchasing.
Yes. Disconnect the negative battery terminal before starting installation and reconnect it only after all steps are complete and the fuse is installed.
Drilling is not always required. You may use an existing vehicle fastener for the ground wire. If no existing fastener is available, drill a 3/32-inch pilot hole. Always check for hidden items before drilling.
