Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the interior trim panel in your rear cargo area. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area. Adhere the black converter box to the frame of the car using the double-sided tape provided. Secure any loose parts of the T-connector with the provided cable ties.
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 tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
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 the trailer. This converter combines 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.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.Easy installation. For the 2020 Outback, instructions were wrong about location of connection. Subaru moved the harness connection to the passenger's side, against the rear of the space for the spare tire. See Image.
John F - 07/25/2021The placement of the connector in the back of the Subaru Forester allowed me to plug in the wiring harness and let the excess cable, box, and fuse sit in the back tray of the forester. I grounded the harness to a nearby bolt and bracket. I feed the wire out of the back of the hatch when needed.
I give this 3 stars because of the excellent etrailer customer service and great installation information and videos. However after 8 months of minimal use, my running lights would not work. After troubleshooting, it appeared that I had 12v into the module (running lights wire). But was not exiting the module. I had to jump this wire to bypass the module. This should be a pass through wire. Why it stopped working is beyond me. It doesn’t instill a lot of confidence especially on long trips
Sierra K - 09/22/2021Harness was easy to install but does take a bit longer than stated. I’m pretty good with DIY electrical and mechanical. It took me about an hour to figure the route and placement of the power conditioner so everything would go back nice and secure. See pics. This is for 2012 Subaru Forester.
Great. Big thanks for your installation video. I followed along and everything went as he showed. Perfect. Took under an hour. Also, the Curt package had all the needed parts for installing. Thanks again.
5 stars for the wiring harness which works just fine in my 2017 Subaru Outback Wagon. The install took some time though (more than it took to install a Curt hitch) because it was hard to locate and expose the car's wiring connector. Would give the install a 3 star for that. The harness instructions have pictures showing where to find that connector behind a panel covering the left rear wheel well. But you don't know exactly where behind that panel, and it's a tight squeeze getting your hand & forearm in there to find it. A small mirror helped. The harness is looped back on itself so you won't see the connector, look for the loop and maybe some blue tape which holds the loop. It's finding that loop that took the time. I routed the harness out through a rubber plug in the spare tire well. It's easy & much neater than running it under the tailgate when you're towing. Remove the rubber plug, slice it from the center to one edge so you can get the wiring harness into it. Figure out how long a wire you need outside the car, reinstall the plug, and seal around the wire with 100% silicone caulk. I connected the grounding wire to an existing bolt inside the car (just secure with a second nut) rather than drilling a new screw hole.
Charles - 03/17/2019Just received my trailer wiring harness, watched the etrailer video for installation and installed it. Took about one hour start to finish. It's going to do the trick. You guys are great with customer service and shipping notifications, I will gladly order stuff from you again. Thank you for your level of service, it was literally best online order experience I have ever had.
Peter - 07/23/2021The Curt connector fit perfectly. The 2021 Outback factory trailer connector the Curt harness connects to is located in the spare tire compartment at the back top toward the passenger side. Only the spare tire compartment needs to be accessed. No other panels need to be removed!!!!
The wiring harness was easy to install on my 2015 Subaru Outback once I had accessed the built-in connector. I utilized the video resources on the etrailer website to determine where the built-in connector was located and how to access it. This was the hardest part of the installation. The rest of the installation was very straight forward and was accomplished within 5 minutes.
Hitch was delivered fairly quickly but as others had experienced I had damaged packaging and needed to spray a little Rustoleum on it in a few places. I was able to follow the instructions that came with the product and did not have to enlarge any hole in the frame to fish the spacers and bolts as in the video. The video was very helpful though and I recommend watching it. I did remove the muffler and that made it much easier. I had the help of a friend with better tools than mine and it took us about an hour. This was installed on my 2017 Forester Premium. Would have given five stars if not for having to touch it up. I also installed the Curt C56040 wiring harness on my own and it went smoothly and exactly as in the video.
The instructions here were "ok", not great. I took out all the floor in the trunk of my Subaru Outback (2012) and turns out half of it could have stayed in. The wire harness on the car is hard to find, Subaru thing, I suppose they figure most people aren't going to hook up trailers. Overall, took about 30 minutes to complete this part of the job. About 90 to do the hitch. First timer here. Still pretty simple. The instructions also do not tell you where to run the end that goes to the trailer. I found a round black rubber plug that goes out the bottom under the spare tire. Run the wire there to the hitch and stuff the plug back in there and tape it down. And done! :)
Joshua - 05/19/2021E-trailer and Curt have done it again with this cheap and easy option. This is the third time I've used their products, and it was the easiest. When I first install the wiring harness it did not activate my trailer lights, which was odd, because the trailer lights worked when hooked up to my other vehicle. After a little troubleshooting I found that the trailer ground was barely connected, so I cleaned all the rust off and put a new end on the wire. Boom, everything worked!!!
Installation was straightforward and uncomplicated. Be patient when looking for the trailer wiring plug. It's buried somewhere behind the driver's side passenger seat in the sidewall. Just be patient so you don't rip the covering. The hitch installs easily and I found modification of the exhaust heat shield to be a very simple process with tin snips and a razor knife (reminder: the heat shield is very thin metal)
Great kit, quality wiring and connectors. It caught my eye Pigtail is right at the lower left rear quarter interior trim, no need to pull that out.
Excellent service from the trailer wiring harness assembly I ordered and installed. Installation was relatively straight-forward; no issues with it whatsoever/ highly recommended !
Dale S - 06/24/2021Between the video and the instructions that come with this it is a breeze to install this wiring harness in your Subaru Outback with no splicing no cutting of wires. This is an excellent product took only minutes to install
Richard - 06/29/2021Fast Shipping, Great Price and perfect fit! Was truly plug and play, I only had to add a ground and it all worked perfectly. A lot cheaper than the OEM one Subaru wanted to sell me. Put this in a 2021 Subaru Crosstrek.
Perfect! I was able to pull back the cover to reveal the connector once the hook is removed. As in the video, blue tape holds it.
Installing this powered trailer lighting adapter was pretty easy, the most difficult part being removal of the trim panels. If you haven't done this sort of thing before you'll find that an inexpensive set of trim removal tools will be a significant help. Subaru did the wiring job properly - contrary to what I expected you don't have to run a hot wire to the battery, a hot is already present at the connector - and the actual hookup is pretty easy. The assembler who secured the connector pigtail at the factory was perhaps overly enthusiastic with the electrical tape so a sharp knife and some careful dissection was required to avoid damaging any wires. While the instructions suggest drilling a hole and using the included self-tapping screw for the ground wire, on my 2017 Crosstrek that wasn't necessary as Subaru has thoughtfully provided a tapped hole for an M6 screw in the perfect location. I used an M6-100 hex head bolt with both a flat washer and a lock washer.
Installing this only took about ten minutes. The Subaru connector for the trailer was easy to locate and access, which helped. Having a tool to remove the panel clips helped prevent any damage to the plastic. The added cable ties helped tidy the installation.
I ordered the wiring harness after viewing the installation video and it took less than 15 minutes to install. A local business wanted to charge me $[xxx] to do the installation and I was able to do the whole thing for under $[xx], including the panel removal tools!
Got the hitch and it is installed. You directions were exceptional. The attached photo shows the wire connector at the rear of the 2020 Subaru Outback. The connector is just a little toward the passenger side of the vehicle from the back gate latch. It was not in the side panel as described on internet posts. Thought you might like to know.
Good Product and video made installation easy. I would recommend buying the tester (had one from a previous install) to confirm everything is functioning before covering it up. Also, good to be able to confirm if its your wiring or trailer if you do have an issue
Easy set up and looks great on my 16 Cr osstrek
Ordering was simple, parts arrived on time, and installation was straight forward. Looking forward to using my new tow bar!
