Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located in your rear cargo area, either behind the driver's-side trim panel or in the spare tire compartment. You will need to remove some interior paneling to access this harness. Once you've plugged in the connector, insert the provided fuse into the in-line fuse holder.
Once installation is complete, the 4-way flat connector will be stowed in your rear cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.
A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required.Excellent product as usual from etrailer. This is probably the third wiring adapter I’ve brought from etrailer & they’re always plug & play. The only thing that varies is where the connector is located in the vehicle. Luckily Subaru places them in an easy to reach location. Out new 2022 Outback was the easiest yet. The instructions say to “Store the 4-Flat connector in the spare tire compartment when not in use”. I don’t like the idea of it being closed in the tailgate when in use so I run it through an oval I cut in the spare tire well using a grommet and silicone sealant to ensure it says water tight. The extra wiring is secured to the back side of the bumper and just enough lead hanging out to connect to my utility trailer.
Installing this was SO EASY. I am not an electrician or a mechanic and have never modified any car before, but watching the installation video on the website was super helpful and I pretty much couldn't have done it without the video! I installed this in 30 minutes. I bet a person could do it even faster than that if they were more experienced than I am!
Love the "no-drill" installation and the fact you can only see the 2" receiver. very clean look unlike other products I see out there. Tow my ATV, boat, trailer, etc with no worries. The trailer connector was an easy plug-in to my vehicle's electrical connection. Videos made the install pretty easy
Everything delivered as ordered with easy installation instructions, and working perfectly. The etrailer website was very helpful in selecting what hardware was needed. A bit disappointed the Curt wireless controller doesn’t seat more securely in the 7- way, but the provided safety strap should keep it in place. Would definitely recommend etrailer and will use it again.

Controller works perfectly when in place. I do now use zip ties to hold it securely in 7-way, which is inconvenient but manageable. Would recommend product to anyone, with that caveat.
Installed pretty well, hardest part was trimming a portion of the bumper for clearance. Only thing i noticed was the hitch inside the receiver has a tad bit of room to move with a trailer being pulled causing noise from the gap. I may try wrapping the hitch with tape to take the gap up. It may be because the hitch sits low on the bumper which causes this not exactly the hitch's design...overall a good hitch system. vehicle connector works great and plugged in easily
Perfect Fit, Great Install Instructions and Fair Price. . . what more could you want. They do their best to package but . . . Fortunately nothing damaged
Fit and utility are perfect! Installed on a 2023 Subaru Crosstrek and mates to a dual ebike rack.
The hitch fit perfectly as did the wiring harness. Hitch install wasn’t as smooth as the video since the video was a 2019 Outback and mine is 2013. I figured it out anyway. Got hung up when I cut out 4” x 4 1/2” fascia per instructions. On the 2013, 4” x 5 1/2-6” is required. The 8 main bolts that hold the hitch and bumper beam were pretty rusty since my Outback is so old. Thank goodness for PB Blaster and 1/2” breaker bar. Not etrailer’s fault but UPS delivered it 2 days later than promised causing wasted good weather and having to finish install in a cold rain. When installing the harness, I couldn’t get by with slotted screwdriver. I had to go buy a trim tool. Advance Auto gouged me $xx for it. It’s basically a split screwdriver. Also the included double sided mounting tape was not included. Fortunately, I had some on hand. Overall, highly recommend. Customer service rep was very knowledgeable and helpful.

This part was quick and easy to order and I received it sooner than expected. My mechanic said the installation was easily accomplished and looks great on my car. I would not hesitate to order from etrailer again!

I had the Tekonsha wiring harness installed by my mechanic and, as far as I know, there were no problems with the installation. The harness has worked perfectly since then.
Good quality product, arrived without a scratch or dent… The directions were clear and concise. For someone who doesn’t do bodywork as a profession, the hitch and trailer wiring were easy enough to install.
Install was smooth and easy. Everything fit better than I thought it would. I did the install in a dirt driveway without jacking up the car and the only issue I ran into was that laying on rocks is not comfortable. Hint for everyone - look up the install for your model year on youtube becaue Subaru changed the location of the trailer plug-in. I did substitute the washers that came in the package with a thicker, wider washer for more surface area.
All items arrived on time and were well packed and as stated. Will update progress after installation. Thanks for the videos, Justin’s suggestions and timely delivery!

Top shelf! Was simple and straightforward to attach. Fittings were located as stated. And it works very well!
Product was easy to install with the correct connector to fit my subaru. And it has been performing quite well for almost a year now.

has been doing fine for yet another year
Hitch came in great shape! Got the car apart the fist time and the hardware was wrong??. I called customer service and they shipped me the right one very quickly. Hitch went on easily with minor issues. The trailer harness was literally a plug in job works perfect. On the Subaru wilderness I was able to use a straight hitch. Over all very pleased.
Easy to install on 2023 Suburu Outback. Wire is plenty long to connect to trailer. Video from eTrailer on YouTube very helpful.
I've had my wiring kit for a year and towed religiously with it. Never any issues highly recommend!
So far so good! Installation was such a breeze - 5 mins max. Have not had a chance to test it yet. Will update once done. Installed on Subaru Outback 2013

After a few tows, can say theres no problem, and works like a charm
After a year with product, I can happily share that it's been great! The install was all plug and play. Most people run the wires out the trunk door but I cut a slit in a plug in the trunk, I had plenty of length to run it through there and it looks great. The other awesome part of this product is that I hooked up to a trailer that back fed into the car, the fuse in this wiring harness blew before feeding into the car, saving me who knows how much trouble. 10/10 would recommend this product

After a year of nearly daily use, I can say this product has been amazing! I only had one incident where the trailer had bad wiring and was back feeding into the car. The accessory fuse provided with this wiring kit blew and protected the cars computer. A $0.60 fuse was all it took to make things good again.
Install was easy and according to the instruction and online video. Cable from the vehicle connection should have been longer. As installed, the fuse is behind a panel that requires removal of two panels and removal of a bolt to access the holder. Should be accessible without tools when in use.

Works as it should, no problems so far.
Exactly what I needed for our '21 Crosstrek. Straightforward installation; plugged into the existing Crosstrek trailer connector and works great! It has a nice long lead for connecting to trailer. The etrailer installation video was a big help.
Just as advertised. The installation videos are SO helpful! Wiring harness installed on my Subaru Outback & works great.
Other than a tight fit to protect from water this wiring harness performs perfectli
Had a defective harness, all light functions worked except trailer lights. Turn signals and brake lights worked. Instead of sending back I just bypassed the wiring box and ran the wire direct and all is working fine. Seems like some quality control issues or I just was unfortunate to get a bad harness.
Super easy to install, great kit. Just wish they would include a rubber grommet to run the wiring through the rear part of the floor by the spare tire. their video suggests to run the wiring out the rear door when towing but I feel the wiring will rub on the paint too much. Another option is to go through the floor below the spare tire but that will put the wiring out right on top of the exhaust / muffler. I drilled a new hole toward the rear of the spare tire area and bought a rubber grommet to fit, as the hole I drilled was large enough to push the 4 pin connector through. All in all, still a great product.
This T-One wiring harness with 4-pole flat trailer connector works well on my 2018 Subaru Forester. The installation video by etrailer.com was very helpful.
