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 Outback (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 350 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.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Subaru Ascent, Forester, Outback, Crosstrek and XV Crosstrek (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

Yes, the Curt 56040 vehicle-to-trailer connector fits Subaru Forester models from 2009 onwards, including 2009–2013 and 2014+ versions. However, the wiring harness location differs between these model years, so follow the instructions specific to your year. The connector does not fit Subaru Crosstrek or XV Crosstrek Hybrid models.
No. The Curt 56040 is designed for Subaru Crosstrek and XV Crosstrek models, but explicitly excludes Hybrid versions. If you have a Hybrid model, contact Curt Manufacturing or your vehicle manufacturer to confirm compatibility.
The Curt 56040 is rated for Signal Circuits at 3.0 amps per side and Tail/Running Circuits at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower, as exceeding it can cause loss of warranty, overheating and potential fire.
You will need a 10mm socket, a ratchet, and a panel trim removal tool. These are the only tools specified in the manual. Additional tools such as a drill may be needed if you must drill a pilot hole for the ground screw, depending on whether a suitable existing screw is available in your vehicle.
Yes. The first step of installation is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal. This must be done before proceeding with any other installation steps.
On 2009–2013 Forester models, the vehicle wiring harness connectors are located on the driver side under the trays in the trunk. You must first remove all trunk floor coverings and the plastic fasteners securing the trays in the center and on the driver side to access them.
On Subaru Outback models, the vehicle wiring harness connectors are tucked up behind the driver side inner fender trim, visible near the rubber grommet in the floor and the cargo anchor. You must first remove trunk floor coverings and trays to access this area.
On 2014+ Forester and XV Crosstrek models, the vehicle taillight wiring harness connectors are located on the driver side behind the rear trim panel. Pull back on the rear trim panel to locate them.
Insert the custom connector end into the vehicle connector. Make sure the connectors are fully inserted with locking tabs in place. Do not proceed until the connection is secure and the locking tabs are engaged.
Not necessarily. First, locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, you may drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
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 if needed. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Locate a flat spot inside the vehicle, near the taillight, and adhere the black converter box using the provided double-sided tape. Ensure the surface is clean and flat to allow the tape to bond securely.
Install a red 10-amp fuse into the in-line fuse holder. This is the maximum fuse rating allowed; do not use a fuse with a higher amperage rating.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent tangling and damage.
After installation, reinstall all items removed during the install and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test the connector for proper function by using a test light or connecting a properly wired trailer.
Test the connector for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring connector will function properly.
Yes, the Curt 56040 fits Subaru Ascent, Forester (all years), Outback, Crosstrek, and XV Crosstrek—but excludes Hybrid models. Confirm your model year and drivetrain before purchasing.
You need a 10mm socket, ratchet, and panel trim removal tool. A drill may be needed if no existing ground screw is available.
Yes, disconnect the negative battery terminal before starting installation.
Drilling is not required if an existing screw with nut is available in the vehicle frame for the ground connection. If not, drill a 3/32" pilot hole for the provided screw.
The maximum fuse rating is 10 amps. Do not exceed this rating or the tow vehicle's lamp load rating, whichever is lower.
The manual does not specify vehicle make, model, or year compatibility. Contact CURT Product Support at 877-287-8634 or visit curtmfg.com for fitment information.
The CURT 13570 has a gross trailer weight (GTW) capacity of 3,500 lbs. and a tongue weight (TW) capacity of 350 lbs. Never exceed your vehicle manufacturer's recommended towing capacity.
Required tools: ratchet, torque wrench, sockets (10mm and 17mm), 8" socket extension, exhaust hanger removal pliers, aviation shears or hole saw, flathead screwdriver or panel trim removal tool, and safety glasses. A 5/8" open-end wrench can substitute for exhaust hanger removal pliers.
Installation is rated as moderate difficulty. The manual does not require professional installation, but proper tools and mechanical knowledge are necessary. Installation involves exhaust lowering, drilling, and precise torque specifications.
The manual does not mention battery disconnection. This hitch appears to be mechanical only with no electrical components.
Yes. You must cut a 1-1/2" diameter hole in the muffler heat shield(s), positioned 2-3/4" behind the front-most mounting hole. Use aviation shears or a hole saw. This modification is required to clear the mounting plate(s).
Cut a 1-1/2" diameter hole in the heat shield(s), positioned 2-3/4" behind the front-most mounting hole. Use aviation shears or a hole saw.
Yes. The installation requires lowering the exhaust. You must remove the two rearmost rubber exhaust isolators from the frame-mounted hangers and the exhaust hanger near the rear differential. Support the exhaust during installation to prevent damage. If the vehicle has dual exhaust, repeat on both sides. The exhaust is reinstalled after the hitch is mounted.
Use an exhaust hanger removal tool to remove the two rearmost rubber exhaust isolators from the frame-mounted hangers. If you do not have exhaust hanger removal pliers, use a 5/8" open-end wrench: slide it up to the rubber isolator cradling the hanger rod, place the flat edge of a pry bar between the wrench and the hanger stop or rod, then rotate the pry bar toward the wrench. Spraying lubricant or soapy water on the hanger rod and isolator eases removal.
Yes. Remove the four M6 x 1.0 muffler heat shield bolts using a 10mm socket and remove the heat shield. If the vehicle has dual exhaust, repeat on both sides. After removing the heat shield, cut a 1-1/2" diameter hole in it (or them), positioned 2-3/4" behind the front-most mounting hole. Reinstall the heat shield(s) after the hitch is mounted and the exhaust is raised back into position.
The fishwire tool guides the carriage bolts and spacers through the vehicle frame rail mounting holes and access holes. Insert the coiled end of the fishwire through the hitch mounting hole in the frame rail and out the access hole. Pass the coiled end through the spacer and thread the bolt into the coil. Kink the wire to keep the spacer separate from the bolt. Pull the fishwire, spacer, and bolt through the frame and out the mounting hole. This prevents loss of bolts or spacers inside the frame rail and guides the hitch during mounting.
The hitch uses four mounting locations. You will fishwire four 7/16" carriage bolts and four square-hole spacers into the frame rail through the forward access holes, one at each location.
Remove the three rubber plugs in each frame rail before fishwiring the carriage bolts and spacers into the forward access holes.
Loosely secure the hitch to the vehicle with the provided 7/16" serrated-flange nuts while using the fishwire as a guide and after centering the hitch on the vehicle. Do not fully tighten until after you have centered the hitch. Final torque is applied in Step 5.
Torque all 7/16" hardware to 70 ft-lbs using a 17mm socket and torque wrench.
Use a 17mm socket with a torque wrench to torque all 7/16" hardware to 70 ft-lbs.
The kit includes: four 7/16" carriage bolts, four square-hole spacers (7/16" x 0.88" x 2.25"), four 7/16" serrated-flange nuts, two 7/16" flat washers, and two 7/16" fishwire tools.
The two 7/16" flat washers are placed between the hitch and the frame on the rearmost mounting holes.
After raising the trailer hitch into position with the flat washers between the hitch and frame on the rearmost mounting holes, center the hitch on the vehicle before loosely securing it with the 7/16" serrated-flange nuts. The manual does not specify a measurement or alignment method for centering.
Periodic inspection of the trailer hitch should be performed to ensure all mounting hardware remains tight and structural components are secure. The manual does not specify an inspection interval or detailed inspection procedure.
Safety glasses must be worn at all times during installation. Support the exhaust during installation to prevent damage. Never exceed your vehicle manufacturer's recommended towing capacity when using the hitch.
The manual does not specify whether additional people are required. The installation involves raising and lowering the exhaust and positioning the hitch, which may benefit from a second person, but this is not explicitly stated.
The manual does not specify whether a lift, jack, or other lifting equipment is required. Contact CURT Product Support at 877-287-8634 for guidance on vehicle access and support requirements.
