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 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.
Circuit-Protected Tail Light Converter
A tail light converter 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. The tail light 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.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

The T-One Wiring Harness for my 2005 Toyota Matrix was extremely simple to install. I think it took me all of 10 minutes. The etrailer staff was incredibly helpful from the moment I ordered. The only advice I have that was not included in the instructions for the wiring harness is to run the trailer wire through the floor, underneath the spare tire. I believe the instructions show the harness simply coming out of the hatch and then the hatch closing on the wiring. I found round, black gaskets underneath the spare that can be removed and allow access to run the trailer wire to the hitch. This lends a cleaner look. Thank you etrailer staff.21871

I bought this as replacement for the U-Haul installed wiring harness that never worked quite right. This unit is much more substantial, has higher quality connectors, and was a cinch to install. I should have gotten this one the first time around.17385

This is a very high-quality product. The connectors on the wiring mated with the factory connectors perfectly. Everything was solidly constructed, and the plug cover is a nice touch. I chose not to drill the hole for the ground wire. Instead I used a stud through the body panel that was near the left tail light (probably holding the light cluster on). Just a few turns with a 10 mm wrench and I was done. Highly recommended.14945

Really easy to install. Took me about 10 minutes. The ground wire is rather short, but you can use the tail light stud rather than drilling. Great product and fast shipping.75398

I loved the quality of the product. I could have used more info in the instructions about where to put the ground wire. Until I took the back light off it wasn't really clear what i might be drilling into. The ground wire was pretty short - so there weren't much choices. 58303

I purchased the "T-One" wiring harness for my 2007 Toyotal Matrix. I must admit that I was not 100% sure the harness would be as simple to install as etrailer described. WOW! was I wrong.... It took me longer to clear the trunk out and open the box than it took to install the harness. It took me less than 5 minutes to install. The only thing is I wish the lead to the trailer was a little longer. However, I am 100% satisfied. Highley recomended product and will shop etriler again.51091

Ordered hitch and wiring harness connector. Being old fashioned I called instead of my first order being on the internet. Talked with Rose and was treated like royalty. Very knowledgeable and accommodating! Order was delivered very quickly as placed. Installation went well. A satisfied customer. 47263

The hitch and electric connector went in perfect. The instructions were great as well as your video. The "Tow Ready" wiring harness is far superior to the last one you sent to me.6721
