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. Powered ModuLite reduces strain on wiring system.Installed on 1999 Subaru Outback.
The wiring harness was a simple plug in, by the left tailight, but a little tricky to get it to run out of the car. There actually was an oval rubber body plug up under the fender that you can just barely see from inside, and you can feel from outside, that I popped out and put a hole in for the wiring harness to go through. It was also a little tricky to get back in place with the wires in it, but it ended up working out nicely.
It really was an easy install, plugged in, wires run outside, fastened them to car underneath, and checked lights. It all worked,
Customer Service really helped me out on this one. I had trouble locating the wiring harness in my 06 Forester. One quick call to customer service had me squared away. BTW-the plug on an 06 Forester is located by the passenger side rear light. It is bundled up next to several other connectors. See pictures.
Very simple install on a Subaru Outback. Much better than the splice method of install.
Fit like a glove
This went on my 2006 Subaru Outback. It only took me 15 minutes to install. That included pulling out the side panels, connecting the wire and putting it all back together. Watch the video first and it is easy.
Hi Patrick, I received the harness today and had it installed within 5 minutes. I loved that I didn't have to cut, crimp, or trace any wires to get my Forester hooked up. Haven't had a chance to hook up with a trailer yet, but looking at the build quality, I don't have any reason to doubt it'll work awesome. Thanks,
Shipping - The hitch, ball mount-kit, wiring harness, and brush all arrived quickly in a single, heavy-duty cardboard box. The packaging was excellent! There had to have been a hundred heavy-duty staples used to secure everything.
Installation - The video and paper instructions were spot-on and made the install much more straight forward. For two non-mechanics, it took us about 2 hours from the time we pulled the car into the garage until all the tools were put away to install the hitch, wiring harness, and mount the balls on the sleeves. We did not lift the car might have made it a little easier but totally doable. The only actual difficulty we had was pulling the rubber muffler mounts off. A little lubrication helps. Reinstalling them is easier.

All items continue to work well with no issues.
Well constructed product, seems well made, but haven't had a chance to use it yet. The OEM installation instructions that came with the product were garbage. English, french and spanish were all stuffed on one side of an 8.5 x 11 page, and the one TINY photo provided for my car model didn't even come close to depicting reality... at least the reality that is my car. Throw the instructions out and watch the videos on the etrailer website and it will help immensely. I was disappointed though that the videos showed their installed product came with double sided tape to secure it, but the one i purchased has a bolt hole at the top and a zip tie, but no bolt or screw. The video and the instructions said nothing about where the product was supposed to zip tied to, or whether it should be zip tied or bolted down. The video and instructions should be updated to regard the actual product being sold. Had to knock off one of the stars. Everything else about the experience was fantastic.

Used my hitch and harness for several fishing and boat camping trips in the last year. No issues whatsoever. Thoroughly pleased with both.
One of the easiest to install automotive electrical accessories I've ever seen. It took more time to empty the Subaru Forester's trunk area of shopping bags, snow shovel, etc. than it did to make the actual installation.
The Subaru wiring connector was not too difficult to find. It was a matter of running my hand along the wiring harness found in the spare tire well until I felt a pronounced lump under the tape. On this particular car, the connector was in the right rear corner of the tire well.

I was a little dubious about closing the hatchback on the cable every time. However, after two seasons of using a trailer for camping trips and hauling things, Ive stopped worrying about it. I still have to make sure that the cable is in the right position before I close the lid not in the latch area and positioned so that there is just enough slack in the line to the trailer. Most of the time I have something in the trunk area that I can set on the cable to keep it in position while I close the lid.

Outstanding quality and so easy to install. The online videos are worth a thousand words...My install looks as neet as the one in the video.
Highly recommend - easy to install and no noticeable impact on the turn signal flash frequency.
Product delivered within a few days. Extremely easy to Install. Took about 15 minutes total. Instead of sandwhiching the connector harness inbetween the rear cargo hatch/door and bumper area, I instead routed the harness through the rubber grommet located underneath the spare tire. This makes for a cleaner install in my opinion. A+++ for perfect fit, fast shipping, and easy install.

Great product, unfortunately I sold the car. I now have a 2000 BMW 528i touring wagon. Wish you made a product for this car that didnt require drilling into the spare tire well. I dont like the idea of mounting a trailer hitch to the body. Need a solution that mounts to a more robust part of the vehicle. Travis
My friend Ann ordered this kit for me, everything is top notch, thank you. However, the problem I have has to do with my Subaru Legacy sedan, I have tried everything to find the vehicle's plug in to install the wiring harness, there isn't one that I can find. I have been in my past a VW mechanic for many years, so unless old age is confusing me, I wonder if you might have a plan. I was originally going to wire the harness in, then I saw how nice it is and thought what a great idea, just plug it in. So, for now I am still trying to find the plug in, they have it for the wagons but not for my 2006 sedan..so far.Thank you

The wiring harness you purchased is a fit for the Legacy wagon model only, not the sedan. The sedan does not have the connector. For your vehicle, youd need part C59236 which would need to be hardwired into place.
Easy once connector is locatedI just installed a hidden hitch and the T-one wiring harness on my 2008 Subaru Outback wagon. The vehicle's trailer harness connector is not where the instructions for the product say it is nor is it where previous users have noted it to be on previous models. For instance, there is no longer a side access panel to the taillight assembly. What you do is open the hatch at the back and pop up the carpeted floor panel to the left of the spare tire compartment, on the driver's side. Just pull straight up - it is attached by three plastic connectors. Then pop up, in the same way, the panel made of cardboard and rigid foam that lies beneath that carpeted floor panel. This exposes a narrow slot at the bottom outer edge of the rear compartment, in the hollow metal part of the car between the outside metal skin and and inside trim. The slot is several inches forward of the tail light. A wire bundle was barely visible at the very rear of the slot, looking like it was running to the taillight. INitially I ignored it and kept searching. But when I ultimately got around to reaching my fingers in and pulling on this wire bundle (after searching everywhere else), it turned out to not be connected to anything, but was the trailer wiring connector that had been bent into a loop at the factory and tucked into the slot. The T-One connector plugs right in. I cut out a square in the cardboard and foam base panel to run the wiring through so that the transformer box, or whatever it is, on the connector cable can fit in one of the spaces between the foam dividers that are glued to the panel and support the carpeted top panel. This way, the carpeted upper panel lays flat when snapped back into place. The cable was then routed down into the spare tire well. I cut a slice into the rubber plug at the rear of the spare tire well, as suggested by a previous user, and then a hole at the center of the rubber plug just large enough to fit the cable without distorting the rubber. I then pushed the plug back in place, with several feet of cable and the connector for the trailer now outside the vehicle. A little silicone glue around the cable where it passes through the rubber plug sealed up the spare tire well to finish the job.

Thank you for a very easy hitch to install. The wiring harness took a little time until I read the information from Craig P. and then it was a snap. Hauled 15 square bails this weekend. Thanks CD

The dealership quoted me $200.00 to install wiring harness for my hitch. I watched your video, ordered the part and installed myself. I just needed to know where the connection was!!! Thank you. It was a great experience

Great
The item fit and worked exactly as described and the video help from this site made it very quick and easy to install. Thank-you
Great product, great company, easy website, and fantastic customer support.
Sorry, no pictures. I like the hitch and harness so far, no problems with towing my utility trailer. The only thing I might mention is that the harness outside of the car is rather long (2 feet longer then what I need), but that's not a problem as I just wrap the excess around the hitch frame, and save it for if I ever need it longer for some reason. There wasn't room inside the car under the mat for the excess length.
I still remember how easy it was to install the hitch, just bolted up the the existing bolt holes in the cars frame. (Subaru Outback)
2009 Subaru Outback PZEV: Install video helped a lot, made everything easy. Wish it could show you how to attach it to the hitch without having to take it out of the car and shut the door on it all the time.

The manufacturer specifically designed the harness so the connector would be deployed from the interior of the vehicle when needed. This is typically done on small SUVs and passenger vehicles that arent usually used for towing. Installing it in this manner keeps the connector protected from damage when its not being used. The rear hatch of your vehicle has weatherstipping thats thick enough that the wire for the trailer connector wont be damaged as long as you avoid the latch area. I have the wiring harness on my van installed this way, and its still working great after 5 years.
Arrived as described and plugged in easily; but that's the end of the good news. Didn't work at all the first time I tried to use it. Voltmeter indicates that power comes out of the car, fuse was fine, but no power reached the flat 4 connector.
I didn't test until over 30 days past arrival, so etrailer won't replace the plug. I had to pay to send it for a warranty return, it's been there for 5 days now, and is currently somewhere in the warehouse waiting to be dealt with. After long waits on hold no specific estimate on timing for return.
I'm out return shipping, original cost, and either can't use my trailer or have to buy another harness.
Summary:
Bad product out of box, OK maybe just a fluke. etrailer customer service not great. Annoyed customer.
Installation was a snap. Remove the cargo area floor, find the vehicle connector, and plug in the harness. No splicing, shrink wrapping, cutting, trimming, or other extra work.

These products continue to meet my expectations and I have had no issues at all. Thank you for offering such exceptional and easy-to-use products.
Product arrived in good time and looks well constructed for the $. In my particular application, I had great difficulty getting the fuse block and black electrical module to sit neatly where it made the most sense as to the logical routing of the wire loom and cables. After attempting to route 4 different ways, I settled on stuffing the fuse block and electrical module into the inner body panel well beneath the drivers side tail light. I believe this part is applicable to several Subaru models and therefore, the length and spacing of the cable where the fuse block and electrical module are along the length of the wiring was not the greatest for my particular vehicle, a 2009 Outback wagon. Not bad, just could not route where I had hoped to for the neatest result.
I was really pleased with how this mounted. The video instructions at etrailer.com were very helpful. As expected, it plugged into the Subaru connection perfectly, and it worked. My challenges were to find and choose the most weather-resistant place for a hole to run the wiring through (I chose an incision in a rubber plug, then put silicone on it) and non-interfering location to lay the wiring. I accomplished those things and had a good outcome. ( I have since sold the car, so can't comment on longer-term usage).
Every thing I get from etrailer is top notch. My car had a trailer hitch & wiring that the previous owner had U-Haul install. The trailer lights were on even when the ignition was off. I ordered the trailer light wiring from etrailer and installed it and problem solved. Thanks etrailer for really good products & instructions.
The trailer wiring kit for my 2005 Forrester arrived promptly. I reviewed the installation video so had an idea about how to proceed. Being used to things NEVER going as smoothly as expected, I prepared myself for some glitches. Much to my delight, removing interior panels went just as outlined in video. The car plug-in was just where the video said it would be. The harness fits perfectly and looks professionally installed with no tools of any kind needed. Total installation time start to finish was less than 10 minutes and most of that was removing the spare tire to affix the harness portion that came with 2-sided tape. I had originally prepared to tackle the project using a universal wiring kit requiring wire location and splicing of wires. I discovered Etrailer while researching how to manually wire the lights. I'm so glad I found this product - it made a difficult job a snap, and the product performs EXACTLY as advertised. My highest recommendation.

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.The wiring, platform, and hitch fit with no issues. A couple of brackets had to be removed but my car service guy said it was no problem. My only problem is I still need a pick up truck. The set up is good for small light loads but my Subaru is just too light weight.
The trailer wiring harness was perfect for my Subaru! It was easy to install and worked correctly.
It helps a lot to read the directions. Well made product and worked perfect first time connected.
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.
True plug and play! Video was great except my harness was on the driver side of my 08 outback not the passenger side.
Worked out great, installed on wife's 09 Outback and not mods needed, direct install just like described.
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.
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!
Product, shipping, website, return policy all were perfect. Will for sure use this site in the future. Only reason i didn't give it full excellent review was because I found my hitch cheaper two on 2 other sites. That being said those sites didn't have the amount of reviews etrailer did which further explained the ease of install by customers....and gave me that desired warm and fuzzy feeling when ordering from the World Wide Web :)
Wiring installation instructions complete with pictures made me feel like superman with a phd. Well done etrailer. Well done.
I'm used to the pain of wiring small trailers but this harness makes it pretty idiot proof. Find the plug-in on the vehicle, plug it in, install fuse, fish the plug through the spare tire area and boom. Easy peasy! I haven't checked it to verify it works but I'm guessing it does. Thanks Etrailer!
Great internet service, good customer service, great experience will use this company in the future for sure !

Excellent product, works great, this is the third product purchased from etrailer they all are quality products
quick install, and worked well! So much easier than trying to freestyle the wiring.
Shipped on time as advertised and complete. Instructions were well written and accurate for hitch itself, but missing a couple steps for the electrical connector kit, (as for taking apart the car trim) so took some time to figure out. (The instructions were from the manufacturer and not etrailer.com itself). Connector worked fine on installation.The fit of the hitch was very precise, so precise that at first I thought it wasn't the right model. But I persevered, and it did fit. The close and precise fit is appreciated, it should help eliminate possible looseness, rattling, and weakness. This is my third Curt hitch from etrailer.com on 3 different cars. I would definitely buy from them again.

These are not the first Curt products I ordered from Etrailer. After a year, I have no complaints about the products, and certainly none about Etrailer. I find the Curt products well designed in form, fit, and durability, and etrailer a fast and efficient way to order them.
2008 Outback
Wires are good quality. Instructions could be a lot better. "remove left and center black plastic, after locating wire..." The words "wire connector located just forward of left tail light assembly would of been better than all of the instructions given. The plastic on the side goes from the tailgate past the back seat and you don;t need to remove it. You only have to remove a screw in the corner but I had no idea which panel it was behind, center or left towards the front back or middle. Step 2 for outback refers to fig A but mine looks nothing like it, mine looks like fig C.
They also say Tools needed : phillips screw driver. That's it. And step 2 they talk about using a pry tool.
The kit also includes a grounding electrical connector, a electrical splice fitting and a self tapping sheet metal screw with no reference as to what to do with them.
Spending ten minutes to write some instructions would make this about perfect.

I use this frequently and have had no problems with it.
Easy peasie is what this is. Quick connect inside vehicle makes it easy and the videos are great too. Thanks again
Complete kit,easy installation. The wiring harness connected directly to the auxiliary wiring found in the left rear inside pockect of our 08 subaru Outback. All lights on our 2 trailers worked the very first time . We've had this kit for a little over a year, With zero problems. Many thanks to Curt for quality product. Also many thanks to etrailer.com (Laurae) for their fast friendly service.

Its a great product. Still performs flawless after thousands of trailer hookups.
Plugged it in, i have lights!! My 02 Forester came with a harness, but when i plugged it into my trailer there were no lights on the right side. I emailed George, got some very helpful diagnostic help, and determined the old harness was faulty. Ordered the new one, plugged it in, viola...good as new :) cant say enough good things about etrailer.com, but i will add that EVERY online business should operate this way.

The curt trailer wire harness is perfect for 2009 subaru outback. thanks so much for info and product. I will buy additional harnesses as backup for our other cars since my 2009 connector broke at an inconvenient time.

Curt trailer wire harness is still excellent after 1 year.
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).

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.
Product arrived on time and was very easy to install. My hook up was right where "etrailer" said it would be and the video made it as simple as plug and play. I hooked it up the day I received it and within 17 minutes I was loading my trailer with deer stands and heading to the woods. The product was perfect in function, price and ease of install. Will definitely use "etrailer" again.
Thank you, John

Still working like new.
The wiring harness/trailer plug worked great, no problems except for the installation instructions. I had to look elsewhere for instruction on how to get to my particular vehicle's built-in plug. The included instructions were not wrong, just too vague. A link to a website with more specific instructions would have been nice. Delivery was quick.

It works perfectly, no problems at all.
Product seems correct but it was shipped in the same box as the trailer hitch with no packing material and the box the wiring came in was smashed by the hitch and it’s contents were scattered inside the shipping box.

So 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!

The location of the connector plug is the same for the 1998 model Subaru Legacy Outback Wagon. I mounted the module under the panel to the left of the spare tire hatch. To remove that panel you remove the plastic trim around the tie down loops and pull the panel up. I removed some of the styrofoam under this panel to mount the module. The connector can then be fished easily up to the tail light connector. The 4 flat connector can then easily be routed out through the rubber plug at the bottom right of the spare tire well.
