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.
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.

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.
The price I got was excellent compared to what the dealer would charge. Thanks to the etrailer installation videos, i was able to do it without difficulty and this is the first time i installed an item like this.
Worth every penny. So secure and easy to plug harness into factory socket at rear cargo access panel. I took the lower bumper panel off so that I could work on it on the bench. I think the 7 pin receiver could be installed with the bumper panel still on the car but placement is critical as to clear the hitch. Taking the panel off was difficult but doable even for this one armed old man. I drilled a rosette of holes in the bumper and finished the hole with a dremel sanding disc. This made a perfect fit. I used bolts and washer - lock washer on the back. This method created a very solid install. You could try a mounting bracket but I don't see and good clean attachment location.
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.
Tom - 12/15/2021Really impressed with the quality of this harness. I really appreciate how the rubber grommet was integrated. Install was really easy thanks to the video guide.
Chris - 02/20/2022I 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
I have yet to install my new hitch or the corresponding wiring harness. However, I received my shipment quickly and in good order. I will be all too glad update my post once I install the hitch.
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.
The T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector was just as described. It fit my 2021 Honda Pilot perfect. I followed the instructions on the video for a very easy installation. Etrailer.com confirmed my order right away, the notified when the order was shipped and delivered. Great Product, Great Price, Great Service!
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.
Amazingly fast delivery. Hitch and hardware all fit perfectly. Wiring harness appears to be high quality. Installation videos were well done, complete and easy to understand and follow.
Steve K - 10/07/2021Quality product. Terrible write up on how to properly install. I have backup sensors and still have no idea where to plug in the second connector with the single blue wire. The instructions say to connect to “mating connection” and i have no clue where that is. Absolutely not helpful. So this caused the installation to take an extra 2+ hours with googling and guessing, and in the end I just gave up on that. 3 stars due to this.
Sierra K - 06/09/2022I am very happy with the results from the trailer hitch and wiring harness I purchased from etrailer.com. Installation was very easy and I saved $800.00 from a dealer install. Thanks.
Steve R - 08/25/2019Works perfect. Easy to install, and great video directions.
Excellent plug and play harness. The instructions video was extremely helpful too. I used this harness with the Honda hitch for an integrated install.
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.
Though it does not say anything in the installation instructions, be sure to disconnect the negative battery cable before connecting. All the lugs for plug are tightly wrapped together and will short out and blow fuses if you don't disconnect the battery first. I found out the hard way as I assumed incorrectly that the instructions would provide that information if warranted. Also, the added plug with the blue wire for backup sensors on the 2021 honda pilot elite is not used. I searched for a long time before I finally found a YouTube video telling me that.
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.
etrailer 7 pin trailer harness and Draw-title trailer hitch for under $200. Install made so much easier with YouTube self help videos. Great deal and the communication was excellent. Would recommend to anyone, thanks again.
Works perfect! I found there was a factory hole in my '21 Pilot tapped for M6 screw in just the right spot to tie down the little black box, with the grounding wire under the same screw, saved a couple steps. The hardest part of the whole install was getting the new rubber grommet to seat in the hole, had to remove the jack and part of the foam thing under it to be able to get it to seal. Tip: Before you push the white plug onto the vehicle harness, get all 7 wires set into the plug so they cannot short against each other, then you probably do not need to disconnect the negative wire at the battery.
We are THRILLED with our 2016 Honda Pilot Elite tow hitch. My 11 yr old and I installed it with zero difficulty and will definitely use etrailer again. Installation was done in 30 minutes flat. It is definitely important to clean out the debris first wtih WD sprayed & scrubbed so the screws/washers tightened properly.
This kit installed perfectly. Instructions were spot on. Thanks guys.
Everything works! What more can I say. The website provided all the information I needed to order the right cable :-)
One of the pins kept pushing out when connecting the bumper end of the harness. I finally got it but it took a lot of effort.
The instructions promised a purple wire in my vehicle to disable the backup sensors but it isn't there. It beeps constantly inside the vehicle when backing a trailer.
