Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.
Once installation is complete, the 4-way flat 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 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.I have pruchee several trailer hitches and products from etrailer over the years and they have always exceeded my expectations with the quality and especially their customer service
Good unit and the video made the install fairly easy. The hardest part was running the power wire from the battery to the taillights inside the car. Heres a tip. To get the wire into the engine compartment look under the dash on the drivers side. The rubber grommet for the main wiring harness has a small hole located in the 4 Oclokish position. Push the wire through that hole. In the engine compartment look for what looks like a small rubber tube with a rubber cap on it which is part of the grommet. Cut the rubber cap off and push the wire through. To run the wire to the back, place it under the kick panels all the way to the back (this is the same way the tail light harness is routed.). I could probably do it now in about 1/3 of the time having done it once. Good Luck!!
easy to follow instructions. works as d escribed.

Havent had time to wire trailer yet.
This kit and the online video made wiring up my 2013 Xb a piece of cake. Top quality components, clear & concise instructions and prompt, professional service at a great price. Worth every penny!
Thanks, etrailer!!

Hi Patrick, and happy new year!Im as pleased with the wiring kit now as I was initially. Its clean, neat
Excellent product. Well made and very easy to install. Their videos on how to install were on point. I could ask for any better. These guys strive for excellence. My kind of people.
purchased hitch and wire harness , hitch says 1/2 hr had it on and done in less than 15 min .Very easy to install. Wire harness was easy as well just when you run you hot wire from the rear to the battery, start at the battery it's kind of hard to run the wire from under the engine to the top with all the wires and stuff trying to fish through it all when you can just drop it down and start zip tying everything .Did all mine in the drive way and it only took an hour. Love the plug and play w/the lights.
Thanks Etrailer

The video crew at etrailer deserve an award! I watched the video before I placed the order then again right before I went to install. It took me 60 minutes from opening the box to the final test of the lights. Everything was covered in the video and the tips specific to the vehicle were spot on. I've never had anything install that smoothly. Thanks video team, you rock!
not a bad little deal, everything fit good! went by youtube vid took me about 5 hours all total plugged ln trailer everything worked!!!! .did not have a lift ,so could have been much quicker, will definitely buy more stuff from etrailer if needed!

T-One Wiring Harness w 4 Pole Trailer ConnectorT-One Vehicle Wiring Harness with 4 Pole Trailer Connector - 118460
The instructions with this are practically worthless as they refer to tiny little black and white pictures which are very hard to see. (A link to a website would have been appreciated.) I elected to run the 12 volt feed from the battery under the car. I brought the wire into the trunk area via the little rubber drain plug under the spare so I wouldn't have to drill though the floor. The white ground wire should be about 16" longer then you could use an existing ground screw which appears when you remove the back threshold. (You need to remove the threshold anyway to run the cable to the right tail light.) I spliced about 16" of wire into the white wire using some splices I had lying around and a piece of the black wire which was longer than I needed. The instructions apparently want you to hang the trailer wiring connector out the hatch and close the hatch on it. As all Matrix owners know the weatherstripping on the Matrix is very poor and not wanting to make it any worse I ran the connector down through the drain hole. A little duct tape to close the hole and protect the wires and it was done. Probably took about an hour. There was a link to a video on installing the wiring that was sent with a request for a review. Unfortunately I did not see it before I did the work but it's just as well as my way was actually quicker. You can feed the cable from the tail light opening down through to the spare tire well without taking off the side panels. Just remove the spare to give yourself some room to get an arm in the hole.
This wiring harness was easy to install and has held up just fine after one year. One thing to complain about is the double sided tape that is provided didn't hold up after one year....but If that's all I have to complain about - I say that I got a pretty good product. Thanks.
This installs easy, even though I had installed another model previously, its a no brainer. Main work is removing the side panels to get to the light wiring and then running a power wire to the battery. Finding a hole in the wheel well isn't hard, but then you have to get on your back and run it under your car and up through the engine which is not hard, just takes time and your on your back on the ground or on a creeper. Plugging into your lights isn't hard, just the running the power wire which I ran along the bottom edge of my frame close to the doors.
Received the product and found the instructions to be difficult to read. Fortunately there were visions on You Tube that provided excellent instructions on how to install the wiring harness. The unit was fairly easy to install and works well.
Product was easily installed. The only challenge was running the power line from the battery to the unit in back. I don't have a lift, and a Vibe is a low profile auto. I'm glad that I'm fairly thin!
The written instructions are fairly good. I had access to an online video of installation which added much to clarity of installation.
Overall a very good product!
Longest part of installing this was running the wire from the back to the battery, but it wasn't hard. Rented a trailer the same day and everything worked perfectly. The step by step video took all the mystery out of how to install it, so it just went in quickly.
The only thing I would caution anyone about is to have a few extra zip ties available because it's a long run under the car to the battery terminal.
Called at 1pm, pushed them to ship same day arrived next day!!! EXCELLENT service and support. I bought from etrailer because of the detailed installation videos, low cost and a fitment for my 'discontinued' 2009 Pontiac Vibe . The packaging of the parts in the box is nicely done and I appreciate the parts at least being made/assembled in Mexico (North America) not China.
This harness is great. Install went as per instructions, hides away when not in use, and my turn signals worked as before with no "fast" flashing from overload. Great product.
It took me about four hours, but I decided to flow a factory wiring harness along the interior on the drivers side. I had to remove several panels and then put them back on when done.
The harness works flawlessly.
Unless the car is on a hoist, running the wiring is harder than shown on the video. Unplugging the connectors is also harder than shown on the video, but it is a good quality product.
Product arrived on time and installed perfectly on my 2013 Scion xB. The installation video provided on etrailer's website was very helpful in making the install go so smoothly. Thanks etrailer!
good directions,a bit more work than otherwire harnesses as you need to bring a feed from battery to trunk,all needed parts are included although you might want a few more zip ties.
Plug and go, patience is required to find way through gasket in fire wall otherwise was very simple. Well worth buying this kit as opposed to trying to wire up something yourself for sure. Will buy again when I get another vehicle.
Great product! Watch the video before starting the installation to make things easier on yourself. Does take some time to route the power wire to the engine compartment.
great service! I loved the installation videos. They made it very easy
Bought May 2021. Worked as designed. I installed in a 2012 Scion xB. I sold the car a few months later so I can't give you long-term review, but I never had an issue while towing.
Trailer wire harness deliveryI received the 2010 Matrix wire harness kit in a timely manner. fast efficient service. thanks!
