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 (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 sedan (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.

Yes, the 10 - 14 Subaru Legacy Sedan Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13158 (Part #5W-CHW-2784) is designed to fit the 2010-2014 Subaru Legacy.
The 10 - 14 Subaru Legacy Sedan Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13158 (Part #5W-CHW-2784) fits the following vehicles: 2010-2014 Subaru Legacy. Always verify your specific year, make, and model before ordering.
The 10 - 14 Subaru Legacy Sedan Curt 2" Class 3 Trailer Tow Hitch + 5-Flat Wiring Kit Tow Boat/Utility Trailer with Surge Brakes 13158 (Part #5W-CHW-2784) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, CURT part number 13158 is designed for 2010-Present Subaru Legacy Sedan models. The hitch has a weight-carrying capacity of 4,000 lbs. trailer weight and 600 lbs. tongue weight.
The CURT 13158 has a gross load capacity of 4,000 lbs. trailer weight and 600 lbs. tongue weight when used as a weight-carrying hitch. However, you must never exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The kit includes: (4) carriage bolts 1/2-13 x 1 1/2, (4) hex flange nuts HFN 1213, (4) square hole spacers CM-SP6 (.250 x 1.00 x 3.00"), and (2) pieces of 1/2" fishwire.
Required tools include: 10mm and 3/4" sockets, 8" socket extension, socket wrench, torque wrench, power drill with 17/32" drill bit, rotary tool or die grinder with carbide bit, and tin snips or file. You will also need a pry bar, spray lubricant, marker, aviation shears, and wire to tie up the exhaust.
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. The installation is rated as challenging difficulty.
Safety glasses should be worn at all times while installing this product.
Yes, drilling is required. You must drill two front holes in the frame rails using a 17/32" drill bit, one hole per frame rail. The holes are drilled using the hitch as a template after the hitch is centered on the vehicle.
The exhaust must be lowered by removing two rubber isolators from the muffler (one on each side) and one isolator from the exhaust tube forward of the muffler. The exhaust is then tied up with wire to prevent damage during installation. After hitch installation, the rubber isolators are reattached and the wire is removed.
Yes, the muffler heat shield must be trimmed. Remove the heat shield by removing four screws with a 10mm socket. Trim 1.125 inches from the heat shield using aviation shears according to the trim diagram to clear the hitch side plates. Save the screws and trimmed heat shield for reinstallation.
After removing the four rubber plugs from the frame rails (two per rail), use a die grinder with a carbide bit to enlarge the front holes just enough to allow the 1/2" carriage bolts and CM-SP6 spacers to pass through. Enlarge only enough for the hardware to fit; do not over-enlarge.
All 1/2" hardware (carriage bolts and hex flange nuts) must be torqued to 110 lb-ft. Initially, bolts are hand-tightened only with a 3/4" socket during positioning. Final torquing to 110 lb-ft occurs after all holes are drilled and the hitch is properly centered.
Fishwire is a technique that uses the supplied 1/2" fishwire tools to thread the 1/2" carriage bolts and CM-SP6 spacers through the enlarged front holes and out through the rear mounting holes in the frame rails. This allows the bolts to be positioned before the front holes are drilled. The process is repeated after drilling the front holes.
Installation sequence: (1) Lower exhaust by removing isolators and tie up with wire. (2) Remove and trim heat shield. (3) Remove rubber plugs from frame rails. (4) Enlarge front holes with die grinder. (5) Fishwire bolts and spacers through enlarged holes. (6) Raise hitch and hand-tighten nuts. (7) Center hitch and drill front holes using hitch as template. (8) Fishwire bolts and spacers through drilled holes. (9) Hand-tighten nuts. (10) Torque all hardware to 110 lb-ft. (11) Reinstall heat shield and exhaust isolators.
Periodically check the receiver hitch to ensure all fasteners are tight and all structural components are sound. This is an ongoing maintenance requirement, not a one-time check.
All non-trailer loads applied to this product must be supported by auxiliary stabilizing straps. Failure to properly support non-trailer loads will void the product warranty.

The kit includes a T-connector harness with yellow and green wire ends, a black converter box, double-sided tape, cable ties, an eyelet, a screw, and a 4-flat wire connector. The yellow wire end connects to the driver's side taillight, the green wire end to the passenger side, and the 4-flat wire routes to the center of the vehicle for trailer connection.
Open the trunk and remove the spare tire compartment cover, jack storage tray, and rear scuff panel (by removing plastic fasteners and pulling up). On both sides, remove the cargo loops holding the felt trunk liner in place, then pull back the trunk liner to access the vehicle's taillight wiring harness.
On the driver's side, carefully separate the vehicle's taillight connectors without damaging the locking tabs. Insert the T-connector end with the yellow wire between the separated connectors, then fully insert both connectors and lock the tabs in place. Repeat this process on the passenger side using the green wire end of the T-connector.
Drilling is optional. Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. If no existing point is available, drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
Adhere the black converter box to the frame of the car using the double-sided tape provided in the kit.
Route the 4-flat wire to the center of the vehicle and out the trunk when in use. When not in use, roll it up and store it in an out-of-the-way location in the trunk.
The white wire is the ground wire. It must be secured to a suitable grounding point near the connector, either to an existing screw with nut in the vehicle's frame or to a newly drilled 3/32" hole using the eyelet and screw provided.
Basic tools include a screwdriver (for removing plastic fasteners and securing the ground wire screw). If you choose to drill a ground hole, you will need a drill with a 3/32" bit. The manual does not specify additional tools required.
Secure any loose parts of the T-connector with the cable ties provided in the kit.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface. Drilling into hidden wiring, fuel lines, or other components can cause damage and personal injury.
Reinstall everything you removed during installation, including the rear scuff panel, cargo loops, felt trunk liner, jack storage tray, and spare tire compartment cover.
Yes, the Curt 56091 is designed for the Subaru Legacy. Confirm your specific model year with the retailer or manufacturer.
No. Drilling is optional—only if no existing grounding point (screw with nut) is available in the vehicle's frame. If you drill, use a 3/32" bit and verify no hidden items are behind the surface first.
The manual does not specify installation time. Contact the manufacturer or retailer for an estimate.
Verify that no miscellaneous items (wiring, fuel lines, etc.) are hidden behind or under the surface where you plan to drill.
