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 Subaru Legacy and Outback (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 4,000 lbs. GTW and 600 lbs. TW. 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 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.

The manual specifies a gross load capacity when used as a weight-carrying hitch, but the exact trailer weight and tongue weight values are not filled in on the document provided. Contact Curt Manufacturing technical support at 1-877-287-8634 for the complete capacity specifications. Always verify that your towing does not exceed your vehicle manufacturer's recommended towing capacity.
You will need: 10 mm and 19 mm sockets, an 8-inch extension, a ratchet, a torque wrench, a drill with a 17/32-inch bit, a rotary tool with a carbide bit, and tin snips or a file. A torque wrench is essential because all fasteners must be torqued to 110 ft-lbs.
The kit 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.
Yes. You must lower the exhaust by removing the three rearmost rubber exhaust isolators from the frame-mounted hangers. Support the exhaust during installation to prevent damage. The exhaust is reinstalled after the hitch is secured.
Yes. You must remove the muffler heat shield and trim it to clear the mounting plate. The trim diagram shows a 1.125-inch removal along the bend line. The heat shield is reinstalled after the hitch is secured.
Yes, drilling is required. You must enlarge the forwardmost hole on each frame rail using a 17/32-inch drill bit to allow the carriage bolt and spacer to be inserted. You will also drill two additional forwardmost holes in the frame rails using the hitch as a template. The manual notes that drilling is required in the install notes.
Use a 17/32-inch drill bit. This is used to enlarge the forwardmost hole on each frame rail to allow the carriage bolt and spacer to be inserted.
Fishwire is a flexible wire used to guide fasteners into frame rail holes that are not directly accessible. For the Curt 13390, you thread a carriage bolt and spacer through fishwire and feed them into the rearmost hole in each frame rail before raising the hitch into position. The manual includes a Fishwire Hardware Technique diagram. Two pieces of 1/2-inch fishwire are included in the kit.
1. Fishwire a carriage bolt and spacer into the rearmost hole in each frame rail. 2. Raise the hitch into position and loosely secure it with hex flange nuts. 3. Mark and drill the forwardmost holes in the frame rail using the hitch as a template. 4. Fishwire a carriage bolt and spacer into each newly drilled hole and secure with a hex flange nut. 5. Torque all hardware to 110 ft-lbs. Do not fully tighten fasteners until all four are in place.
All hardware must be torqued to 110 ft-lbs. This applies to all four carriage bolts and hex flange nuts. Use a torque wrench to ensure proper tightening.
Yes. After raising the hitch into position, center it on the vehicle before loosely securing it with hex flange nuts. This ensures proper alignment before the fasteners are fully torqued.
After installation, verify that all fasteners are tight and all structural components are sound. The manual recommends periodically checking the receiver hitch to ensure that all fasteners remain tight and that all structural components remain in good condition.
All non-trailer loads applied to this hitch must be supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty. This applies to any load that is not a trailer.
No. The manual explicitly states: "DO NOT EXCEED VEHICLE MANUFACTURER'S RECOMMENDED TOWING CAPACITY." Even if the hitch has a higher capacity rating, you must follow your vehicle manufacturer's limits.
The manual recommends periodically checking the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. No specific interval is provided; perform checks regularly as part of vehicle maintenance.

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.
