Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove interior trim paneling to access the connection point. Once you've plugged in the T-connector, insert the included 10-amp fuse into the in-line fuse holder.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your 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 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.I'll start off and say that this product looks and feels five star, but I'm docking it one because the installation docs and video are very mismatched and conflictive. The one-page paper installation doc was barely applicable, while the video was much, much better. Use it! Pulling out the few pieces of the car necessary to gain access to the OEM plug was relatively easy. Where things got messy was where to actually put the "control" block for this thing. The video shows a self-adhesive backing which was not present. There are included zip-ties but no really good place to use them. I didn't want to leave it loose in there to become yet another rattle in the car, so I ended up securing it with that foil tape used for duct-work. It seems to have done the trick. Routing the cable was easy, and I dropped it under the spare tire and through a grommet, resealing it with silicone when I was done. I'd have loved to see some kind of cable management included for under the car and around the hitch, rather than the four independent wires being just ad-hoc wrapped around things. Electrical testing worked flawlessly, and all outputs were signaling correctly. 529224
Great product. This took under 5 minutes to install. The Forester 2006 had the electrical connector under the floor tray on the passenger side at the very rear under the taillight hidden by a plastic flap. Lift up flap, plug in, then snug the hardware into the side well. You can run the wire and trailer connector through the 1" hole at the rear of the wheel well capped by a large rubber plug so the wire disappears under the spare. 94920
The product works but it is always drawing power. I need to unplug it from the cars wiring harness when I do not have a trailer attached. (the plug connecting the "circuit box" to the cars wiring harness.) At night when the car is parked (completely turned off) and a trailer hooked up to the wiring, you can see the tail lights glowing with a faint light. This should not happen. This is a replacement harness for one that I left plugged into the car all the time. It stopped working unexpectedly and I had to order a replacement. The circuit box had swelled probably by 10% to 15% in size. It happened after warranty so I paid for it hoping that it was a fluke. I would not order this product again. 259312
Having already purchased two trailer hitches several years ago for my Tribeca and Forester to support our bike racks, it was natural to return to such a superb company to purchase a wiring harness connector and lighting kit for our new utility trailer. I had cursorily enquired at the local auto parts store what I would pay for those two items and the clerk cheerfully told me he could have the products shipped to the store within two weeks for $90.00 including shipping. When I told him e-trailer would have it to my house in three days for only $68.00 including shipping, he just shrugged his shoulders and closed out of his catalog screen. True to their word, e-trailer had the two parts to my house in three days, and this weekend I will begin the clean up of the utter destruction in our woods caused by a hellacious Maine winter. 110 inches of snow caused more damage than we have seen in years. Thanks, e-trailer, for providing us with such quality service for our Subarus and our new(used) utility trailer 191270
Box arrived with a couple holes torn and hitch hanging out one corner, but l accepted it hoping for the best. Installed hitch and wiring harness by myself in about 2 hours from start to finish... probably could have done it faster with help, starting the bolts was frustrating but doable nonetheless. Product seems well made, no complaints there. Dealing with Etrailer has been a good experience so far and will most likely be a returning customer. Attached pic of hitch hiding under bumper, just how l like it! 124424
This harness replaced a Draw-Tite one that failed after about 4 years of occasional use. I'm hoping this one, with revised circuitry, lasts longer. It was trivial to install, as it has the correct pin connector for my Forester. In contrast to the previous harness, it has a dust cover and a 10 amp fuse. It worked fine on a 200+ mile drive (including the load for a camera I use for a rearview in my travel trailer). 212343
This harness still works perfectly. Like others who bought it, I keep the wiring inside my forester when not in use, rather than mounting the external portion of the connector to the receiver hitch.
Kwame M - 07/18/2016So far everything worked out. Shipment took 3 days instead of 2, but was happy as many packages were delayed longer because of the storm. Thank you for getting it out the same day as I ordered. Installation went well and was just as your video described. Will test it this afternoon when I pick up the trailer. Even in 10 deg F weather, the installation went very easy. Good thing, finger tips were cold! 116065
Worked out great. used it about 5 times so far. Easy to use, and easy to install.
Drew P - 02/20/2015I purchased a trailering wire harness for my Subaru forester . Installation was a breeze and work perfect. 726254
Worked perfectly with my 2002 Outback wagon and Uhaul trailers. On this model, the harness attachment is found in the back underneath the carpeting and foam over the passenger side wheel well. 725238
Received my trailer harness this afternoon from etrailer and had it installed in my B9 Tribeca in 15min (incl. Opening the box and walking out to the car). The harness worked perfectly as promised. The only thing I would warn anyone about it that when you plug your harness in and it doesn't work check the fuse holder that's part of the harness. My fuse wasn't in there, after I put the supplied fuse in everything worked great. That was so freakin easy compared to the way I used to do it, get out the tester, lay under the car for 2 hours on my back. BUY IT, it works so easy! Oh the quality of the harness is really good. It was made professionally, everythings water tight and ready for your trailer pulling. Happy towing 724671

This is an excellent product. I have installed the the trailer wiring harness, the instructions were clear and concise and the installation took about 10 minutes. I hope to install the hitch tomorrow. I reviewed the instructions for that installation and looked under my Subaru. The hitch installation should take an hour or so and I'm slow. Again, excellent product and clear instructions. If you need a hitch for your Subaru, this is the way to go. 705303
After having the car wired at a national trailer rental company,, incorrectly!! I tried to figure out what was wrong for several hours. Purchased the CORRECT connector from etrailer for a fraction of the cost, followed their installation video and 10 minutes later eureka!!! 698120
Easy to install 696877
Plug and play perfect. 696332
Wiring harness plugged in and works great. Plenty long enough to use on any trailer. 691287
The receiver for my 2006 Subaru Forester arrived quickly. Installation was straightforward and pleasant, especially with the video tutorial links. A bit off-putting to slam the hatchback on to the trailer wiring, but as advertised, it hasn't hurt the wires yet, and the hitch has seen plenty of action since installation last year. You all sell a well-made product, and your promptness and service have been top-par. Thank you for that. Pat yourselves on the back! 691610
Everything fit and it plugged right in to my vehicle wiring harness 688604

Fit perfect, easy installation 664298
Product worked well as described, plugged right into an existing connection in the rear cargo area of my 05 Subaru Outback wagon. Price was reasonable, shipping faster than given ship estimate, and customer service was very good. I would recommend this source and product. 656182

I bought this to make the installation of a trailer hitch simpler; custom fit for my wife's Subaru, and the video told me everything I needed to know to install it. 652859
Easy to install and it works. 651970
We have not yet installed this part, but once again Gwen was AMAZING at handling my questions and making sure that I got the parts that I needed for the job I was doing. Thank you Mrs. Jessica Howe 650617
Easy to install as described and instruction videos what more can u ask for. Only issue i had was that they didnt have my vehivle for the install of the wires they had a 2000 subaru outback i have a 05 i thought the tow wire would b on sameside as the 2000 but it wasnt it was on the driverside instead. But still great product so far. 646657
5 min install. Happy. 644901
Finish was outstanding ,fit was PRETTY GOOD ,the video for receiver and wiring harness " worthless" ,not even close to 'apt' for a 97 ,took me 2 hrs ,2 floorjacks lots of prying and cussing ,final installation looks great , on this model the front fish bolts gotta go in 1st and then it can be jacked into place , harness plugs in on drivers side ,for the $$ , a hitch would have been nice ,all in all i will recommend your products and probably use again .Also customer service is the best out there !! 643168
Second time dealing with this company and I have not been let down yet, good prices and even better service and delivery time. Highly recommended 643115
Worked perfectly, the video was helpful for the installation. Install the fuse in the fuseholder before using. 643025
All was what it was supposed to be and here quickly w/o all the craziness of extra costs to get here "faster". 639284
Used it on a small trailer I built to haul model airplanes. It made the wiring hookup very easy and it works great. 639093
