Description

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 (factory tow package required; 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.

    • 1,2,3 and you're done!
Fit the car perfectly, simple to install, saved over $100 by doing it myself v.s. having the hitch installer do it. really only takes 15-20 minutes and most of that time is removing and installing the car interior pieces that have to come out to access the in-car harness. Be sure to use a harness tester to confirm that everything is working properly, I had to disconnect and reconnect the harness connector once to ensure a solid connection, also be sure your ground is really electrically connected to the frame, some metal pieces of cars today are not electrically bonded to the frame. Everything is working as expected. ... show more

    • Great Kit but there is a trick to finding the factory wiring in an Outback.
I just got finished installing this but I assume it will hold up. I installed it in a 2016 Subaru Outback 3.6R Limited. I bought an ECO Hitch from Tork Lift Central and they sold this adapter as well. It was almost twice as expensive on their website so I bought mine here. If you are still looking for a hitch I highly recommend theirs. Much better looking than the other aftermarket options and I got a 2 inch receiver unlike the $800 plus one from the dealer. Installation isn't too bad until it is time to find the plug and make the connection. Most of the online installation videos gloss over this part. I read another review somewhere that mentioned removing the cargo tie down point behind the drivers side rear seat. The plug is basically right next to the opening. i used a flat blade screwdriver to break the tape and pull the plug out the hole. The other review also mentioned fishing the adapted wiring up from under the bottom of the trim panel and pulling it out if the hole too. Then you simply plug them in and pull the wiring back behind the trim panel. Right by where you pull the wiring out you will see a couple studs with nuts on them. I cut off the small ring terminal and attached the larger one provided in the kit. It fit perfectly over the stud so I removed the nut and attached it there. From here it is your preference what to do with the wiring. I tucked it up behind the trim panel and routed the wire under the foam panels under the floor to where the spare tire is. Another review mentioned making a short extension plug to run out from the spare tire compartment through a grommet that is located there. This way you won't risk damaging the end of the wiring kit. This will probably only be easy if you are removing the bumper to install the hitch.Hopefully this helps someone else like other reviews helped me. I recommend this kit and it seems well made. Plus they included the ring terminal I needed so I didn't even have to run to the store to buy anything else. ... show more

    • Subaru Outback Onyx
Installed in my 2014 Outback this afternoon. Needed to do a few minor modifications. Cut off and crimped on the supplied larger ground terminal so it would fit on an existing screw. Add split tubing over the wire for extra protection. The opening in the back for the wire to go through was slightly too small for the 4 pin connector to go through, so I enlarged it slightly and then filled it with sealant. Other than that, it installed easily and worked perfectly. ... show more

    • Plug-nPlay
Installation for this could not have been easier (Subaru is very helpful with their plug location) and only took a few minutes. The Curt harness connection was perfect and everything worked right out of the box.

    • Perfect for 2024 Subaru Ascent
Easy install. The ground wire took about 10 minutes to figure out where to go and install but not a big deal with a drill/driver.
