Quickly and easily install a 7-way, RV-style trailer connector on your vehicle with this custom harness. T-One connector plugs into OEM tow package wiring harness - no cutting, splicing or tapping required.

    • Designed for use with a factory tow package
    • Compatible with 4-pole, 5-pole, and 6-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Tow harness with 7-way connector plugs into connection point behind rear bumper
    • Converter connects in rear cargo area
  • Includes Modulite to ensure that your vehicle's wiring matches that of your trailer

    • Tail lights: 12 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness. The connection point for the 7-way harness is located behind the rear bumper. The converter plugs into the factory wiring harness in your rear cargo area, on the driver's side. You will have to remove the floor covers, cargo trays, and some interior paneling to access this harness. Once you've plugged in the connector, insert the included fuses into your fuse panel as indicated in the instructions.


Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the separate brake and turn signals from your vehicle's 3-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 bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

I must say I like having my etrailer equipment installation was easy. But I really wish I had installed the factory hitch. Only because the provisions for mounting the wire harness is much much better. etrailer IS GREAT WITH ALL THAT THEY DO

Classic under promise and over deliver. The videos were extremely helpful and everything went together just as described on my 2020 Honda Pilot. I ordered the Drawtite receiver and the T-One 7 pin harness. Only thing that was a bit frustrating was the location of the onboard pre wired connector on the Pilot. It would have been helpful for a caution about needing to fish up into the body to find that connector, it isn’t readily available to find.

I used this wiring kit with the Honda hitch. I would recommend installing the 7-way receptacle to the mounting bracket on the hitch prior to installing the hitch to the car. You will need to drill holes in the mounting bracket on the hitch since the ones on the receptacle don't line-up with the ones on the bracket. I used four stainless steel screws and nuts with nylon inserts to connect everything together. The rest of the installation went just like the video, easy.

If your Pilot came from the factory with backup sensors like the touring and elite models come standard with, you will be searching for a plug to hook the blue wire up to that is in this kit...well there isn’t a place to hook it up. The blue wire will only hook up, if for instance your backup sensors were installed aftermarket possibly at the dealership, not the factory. Basically if you find the tow wiring hidden behind the drivers rear interior trim, and you only find one plug, not two, don’t worry about hooking up the blue wire. My car is a 2019 Elite, with factory reverse sensors. I did not hook up my blue wire, and it Works perfect. Install was simple once I learned this.

Very easy to install. Everything I needed was right in the plastic bag of hardware. The head of the self-tapping screw was smaller than the hole in the lug on the ground wire so I had to use a washer between the two. Also, I didn't get a nice clicking sound when I put the white wire into the connector, but all the rest were good. I hope the white wire stays put, but I think it will because of the little plastic piece used to secure all of the wires. I probably didn't need this fancy of a harness for my infrequent, light-towing needs, but it really was a dream to install. Would highly recommend.

Install was easy however the electrical connections were not clear in the black and white instructions included, had to use the color picture on the website to properly wire the 7 pin connection. Any questions were answered by their video. Only wished that I had gotten a model with both the 4 pin and 7 pin connectors.

The wiring harness was complete and easy to install. The best part was that the instructions were easy to follow and accurate. The only thing I would add to the kit is the bracket for the 7-way connector, that way you would have the option to use the bracket or cut a hole in the plastic below the bumper. I chose to cut the hole in the plastic below the bumper.

I really liked this product. Installing this item was a snap. The video was a big help. I remember installing universal kits to my vehicles back in the olden days and I do not miss that. It literally took me a fraction of the time and was worth the few extra bucks to get something made for my vehicle. Thanks again. Still working well btw. 2018 Honda Pilot towing a 21 ft camper. Only thing I would change is make the hitch plug mount and screws stainless for us living in the rust belt as those pretty much instantly got surface rust.

Great customer service. Fast shipping. Video by etrailer makes installation less intimating. I connected the wiring harness without opening the panel in 5 mins. I used the index and middle finger to hold the vehicle harness; with T-one hardness in my palm, I squeezed my hand to latch; heard a click/locked sound. At least give it a try first before you open the panel.

I used an OEM hitch and then ordered this electrical system. Videos were spot on for directions and it was easy to install. Only issues were that the holes are meant for the aftermarket hitch and do not line up with the OEM hitch plate. Had to drill holes which only added a few minutes time. Also, bolts are not included for fastening the end piece to the hitch. I used small stainless to avoid rust issues. The included self tapping screw for the ground is also not a good idea since they can come loose over time. I drilled a small hole, scrapped away the paint for a good ground and used another stainless screw and nut. Quick tip, Install the end piece to the hitch before installing the hitch on the car. Very difficult to do afterwards.

This wiring harness was awesome! I took my laptop out to the used Honda Pilot we had just purchased for out tow vehicle and played your installation video right in the back of the pilot. Everything was just as described in the video: each part to be removed, how to do it and especially finding the wiring plug from the factory right where the video said it would be. It was easy. I was so happy.

I used the brake controller and wire and wire loom on my 2017 Honda pilot and found it to be a perfect fit and a easy hook up as far as the wire loom and the controller was just as easy and worked well as we took a trip from North Carolina to New Mexico without any problem with the brake controller. Good demo an hook up, also. Thanks for the video.

It took longer to gather my tools than to install this unit. The hardest part was getting the factory connection loose from all the tape Honda likes to put on. My only suggestion for install is to skip drilling the 3/32" hole for a ground like the instructions say to do as on the 2016 Pilot there is a 6mm tapped hole already in the compartment that makes a great ground connection. Total time for install was about 20 minutes. I mounted my connector to the hitch cover on the drivers side of the car so the wiring harness was a little long. I just looped it and zip tied it to the car frame. All in all worth the money so I didn't have to find and splice wires.

The hitch and harness work flawlessly. Great products and easy to install.
