Whatever the next checkpoint is on your adventure -- whether it's getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Subaru Legacy and Outback (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4" receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid A-coat and black powder coat, giving them long-lasting rust and wear resistance.
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 Legacy (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.

You will need: 10 mm and 19 mm sockets, an 8-inch extension, a ratchet, a torque wrench, a drill with 17/32-inch bit, a rotary tool with carbide bit, and tin snips or a file. The manual also notes that drilling is required and fishwire hardware is used.
Yes, drilling is required. You must enlarge the forwardmost hole on each frame rail to 17/32 inch to allow the carriage bolt and spacer to be inserted. You will also drill new holes in the frame rail using the hitch as a template during installation.
Yes, you must remove the muffler heat shield and trim it to clear the mounting plate. The trim line is marked 1.125 inches from the edge. See the Heat Shield Trim Diagram in the manual for the exact trim location.
Yes, you must lower the exhaust by removing the three rearmost rubber exhaust isolators from the frame-mounted hangers. You must support the exhaust during installation to prevent damage. After installation, you will reinstall the rubber isolators and raise the exhaust back into position.
Fishwire hardware is a technique used to insert fasteners into frame rail holes that are not easily accessible. The manual includes 2 pieces of 1/2-inch fishwire in the parts list. You will use fishwire to insert carriage bolts and spacers into the rearmost hole in each frame rail (step 4) and into each newly drilled hole (step 7). The manual references a Fishwire Hardware Technique diagram for detailed instructions.
The hitch includes: 4 carriage bolts (1/2-13 UNC, 1-1/2 inch, Grade 8, yellow zinc), 4 square-hole spacers (0.250 x 1.00 x 3.00 inch), 4 serrated flange nuts (1/2-13 UNC, Grade 8, yellow zinc), and 2 pieces of 1/2-inch fishwire.
All hardware must be torqued to 110 ft-lbs. This applies to all four carriage bolts and serrated flange nuts after the hitch is fully installed and aligned.

Yes, the Curt 56246 Custom Wiring Harness is designed for Subaru Legacy passenger cars. The harness connects to the taillight wiring on both driver and passenger sides inside the trunk.
The Curt 56246 is a custom wiring harness that provides a 4-flat connector for trailer lighting. It integrates with your vehicle's existing taillight circuits to supply power to a trailer. The harness includes a converter box that processes the vehicle's taillight signals for trailer use.
The harness is rated for 3.0 amps per side on signal circuits and 6.0 amps total on tail/running circuits. The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed the product rating or your vehicle's tow lamp load rating, whichever is lower.
You need a panel trim removal tool. If a suitable grounding point does not exist on the vehicle frame, you will also need a drill with a 3/32" bit to create a pilot hole for the ground screw. A test light or properly wired trailer is needed to test the installation after completion.
The harness includes a T-connector with yellow and green wires, a white ground wire with ring terminal, a provided ground screw, a black converter box with double-sided tape for mounting, a 4-flat connector with dust cover, and cable ties for securing loose wires.
Yes. You must disconnect the negative battery terminal before beginning installation. Reconnect it only after all installation steps are complete and items removed during installation have been reinstalled.
Remove all trunk floor coverings, the scuff panel (secured by three push fasteners), and the felt trunk liner push fasteners and cargo fastener on the driver side. Be careful not to damage the alignment tabs on the back of the scuff panel or the locking tabs on the taillight connectors.
Locate the vehicle's taillight wiring harness connectors inside the trunk behind the taillight housing. Separate the connectors from the taillight housing carefully, taking care not to damage the locking tabs. Insert the T-connector 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 T-connector end with the green wire.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The area should be clean and flat to ensure proper adhesion.
Drilling is required only if a suitable grounding point does not already exist on the vehicle frame near the taillight connector. If you must drill, create a 3/32" pilot hole in an area free of rust, dirt and paint. Before drilling, check for miscellaneous items hidden behind or under any surface to avoid damage and personal injury.
The pilot hole should be 3/32" in diameter. Drill in an area free of rust, dirt and paint, and secure the white ground wire using the ring terminal and provided screw.
The yellow wire connects to the driver side taillight wiring, and the green wire connects to the passenger side taillight wiring. Each T-connector end is inserted between the separated connectors on its respective side to tap into the vehicle's taillight circuits.
The white ground wire provides a ground connection for the harness. It is secured using the ring terminal and provided screw to an existing screw with nut on the vehicle frame, or to a 3/32" pilot hole drilled near the taillight connector. The grounding point should be free of rust, dirt and paint.
The black power wire connects to the vehicle battery and must be routed as shown on the included CME-PCL-INS sheet. The battery connection must be fuse-protected with a maximum 10-amp fuse. Do not exceed the product rating or your vehicle's tow lamp load rating.
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 it to the center of the vehicle and out of the trunk. Secure any loose wires with the provided cable ties.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your vehicle's tow 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. This is especially important when drilling the 3/32" pilot hole for the ground screw.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer. This confirms that the signal and tail/running circuits are operating correctly.
Reinstall all items removed during installation: the felt trunk liner, the scuff panel, and all trunk floor coverings. Reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
