CURT 56040 4-Pin Wiring for Subaru Ascent, Forester, Outback, Crosstrek

Worked perfect on my 2026 Subaru Forester. For this type of wiring and a newer vehicle, be sure to check with manufacturer as well as Amazon for compatibility. I found that Amazon did not know that this wiring would work for my new car. Their options were far more expensive and required wire splicing and running dedicated power. Only issue I had when installing was that one of the clips went flying when I pulled it. For the other clips I just put a rag over it when pulling. I did find my wayward clip half way down the driveway.

High quality, quick & easy to install, great quality for the price. Highly recommend

Very easy. Installed on my 2026 Forester. The only fiddly part was getting the factory pig tail out from the back left corner. It is taped back on the the harness. I used a linoleum knife to reach in and cut the tape. From there you can pull it out and remove the tape. I replaced the terminal ring on the ground wire with the larger ring supplied in the kit and then was able to use the bolt holding the metal bracket that supports the carpeted floor panel. I put the controller in the center below the hatch catch, reinstalled the styrofoam cubby and coiled the trailer wire in that ready to feed through the bottom of the hatch when needed. Make sure the rubber weather stripping goes back over the plastic sill when reinstalling.

Our Subaru came with a hitch receiver but no electrical connections, which are necessary for even a small Uhaul trailer, so I bought this after reading an install guide online... and it works perfectly! The hardest part of the whole process is getting to the electrical plug behind the cargo bay side panel, but even that is pretty simple (tip: the two pieces of blue tape wrapped around the plug wires can be slipped off by hand, even if you can't get your head down there to see them). After that, you just plug this connector in, drill a small hole to attach the ground wire to the car frame, and stick the signal converter behind one of the panels (double-sided tape included). There is a rubber cap for the 4-pin connector, so you could technically leave it dangling out the back of the trunk, but it stashes nicely in the spare tire tray under the cargo area floor when not needed.

Works well but recently the running lights don’t light up. Break lights still work though.

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.

super easy installation. took maybe 15 minutes on my 2025 crosstrek. subaru makes it easy by having a plug in connector accessible. Watch the you tube video!!

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.

Facilidad de conexión y buen precio.

Incompatible with 2022 Subaru Forester Waisted my time

Bought a new trailer and needed lights. This was so easy to install and I had it hooked up in minutes with zero issues. Works great. Excellent build quality. Just what I needed

Produit tel que décrit. S'installe aisément après le branchement de l’auto. Se cache bien. J'ai suivi un tutoriel en ligne.

Installed this trailer light connector on ‘21 Crosstrek. Easy plug-n-play harness. Simple 15 minute install.
