Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the rear interior trim panel on the driver's side of the rear cargo area. You will need to remove access panels, threshold, trunk floor panels, and trays to access the harness. Once you've plugged in the T-connector, pull back the interior trim panel on the driver's side and locate the ground stud. Loosen the bolt, place the screw eyelet on the stud and re-tighten the bolt.
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 plugs 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.
With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

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. Powered ModuLite reduces strain on wiring system.Great product. Works perfect and was very easy to install and disappears when not in use.
Very helpful staff. I had trouble with the shipping companies which sent the order to the wrong location, not etrailer's fault. The team at etrailer resolved the shipping issue. I am satisfied with the merchandize I received, etrailer stands behind their products and were helpful in selecting the right combination of components. Great company, great phone service!
Easy install. Bought this with the Curt Class III hitch. All components match up and install without a struggle. The Tekonskha Custom Fit harness incorporates turn signals, running lights and brake lights.
This worked well on my 2020 Subaru Ascent. The only reason for 4 stars instead of 5 is due to there not being a clamp or something to hold the final cable in place. It isn’t a big deal, you can tuck it into the bumper and that seems to be fine but would have liked a better setup there. Overall great harness and pretty easy to install.
Very easy installation, I followed the video online and got it down very quickly.
Great instructions and installation!
I was impressed with the installation service, the finished appearance and the price.
Paulette W - 01/03/2022What you see is what you get. Works perfectly. Instead of leaving it laying in the cargo bin i ran mine through the grommet for the tail light over the bumper and on to the hitch. That was a bit of a struggle with the size of the cap since it didn't flex very well but not major. Arrived ahead of expected shipping date with everything needed to install.
Product was as described. It fit perfectly on my 2020 Subaru Ascent an was very simple to install the hitch and harness. Took about about 75 minutes. Products were high quality. Also saved about $700.00 if a Subaru dealer installed. When not in use it is totally concealed by the center removal bumper face plate.
Highly recommend this product.
Instructions were clear and easy to understand so much so I had my 14 year old son install this unit.
Very easy to install. The only difficulty is actually getting to the place where the harness is to be placed. Instructions are easy to follow and, with a little care, the system can be installed with no issues.
Bruce - 08/24/2021Great product! Ease of installation. Super fast shipping. Definitely recommend for all your truck and trailer needs.
I purchased this for my 2019 Subaru Ascent along with a Drawtite hitch 76253 and a brake controller with a dash mounted control knob so that the actual controller is hidden near the steering wheel shaft hidden under the dash. All three items were installed and we enjoyed a great summer of RV trailer camping in the summer of 2019.
John - 05/01/2021I have been using etrailer.com for several years on multiple vehicle hitch and wiring projects and I have always been very pleased with the product and my experience. This time was no different. I needed to install a hitch and wiring harness for a 2020 Subaru Ascent. The parts that were matched with my vehicle online fit perfectly. The instructional videos that accompany every part are outstanding. Each step is clearly explained and easy to follow. Once again, etrailer.com delivered exceptional service, prices, parts, delivery, and everything else I needed to complete my hitch and wiring project in just a few hours. I highly recommend etrailer.com and I will continue to be a customer for several decades to come.
Great experience. Currently deployed and wanted to get my wife a hitch for her new Ascent. The Subaru dealer really screwed up everything but Arthur at ETrailer saved the day. Super friendly and helpful. Fast shipping and got exactly what was ordered! Highly recommend.
Works perfectly. Easy install.
Super easy to install and still working a year later
Easy installation, the wiring options video helped me pick out what was best for me and item came with everything needed.
Worked great
Super easy to install.
etrailer is always helpful. This is exactly what I needed and works perfectly.
The install was straight forward. If I hadn't been also installing a trailer brake controller the entire install would have taken all of 15-20 minutes. Very simple!
Works great fit perfectly.
I haven’t installed it yet but the how videos makes me believe it will be simple. Great web site for ordering and quick shipping.
Works great super easy install .
