Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is 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, you will have to route the harness through the jack storage compartment to the center of your vehicle. Afterward, locate the fuse box under your hood and insert the provided fuses.


Once installation is complete, the 4-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 4-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 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 bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

T-One Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector - 118760

Average Customer Rating:  4.8 out of 5 stars   (328 Customer Reviews)

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-One connector plugs directly into OEM tow package wiring harness - no cutting or splicing required. Powered ModuLite reduces strain on wiring system.

by:

The wire harness was easy to install in less than 40 minutes. The instructions should have larger photos with more details. Locating and connecting to the existing vehicle connector took a little more disassembly than the instructions indicated but I was able to manage it in a short time. I appreciate the fact the new harness had a grommet to seal the hole in the body.



by:

Shipping was very fast. I watched the installation videos prior to putting it on. I was fortunate to have a friend who has a hoist. It really went on just as easy as the video shows.

I bought the wiring harness as well. That was an easy install too.

The hardware is of top quality. I'm glad I dealt with etrailer. Buy from them. You won't be disappointed.

Just a mom who needed to add a hitch to her Honda Pilot. The process is SO user friendly! I used a video on the website to select the best hitch option, effortlessly used the website to find the hitch and suggested items, and even called customer service to make sure I was ordering the right parts for my make and model. When everything arrived, I watched the installation video. Itā€™s CRAZY how easy the process was! The total cost was less than half of what I was quoted at a local shop for a hitch and installation. THANK YOU ETRAILER!



by:

Quality of products was excellent.
YouTube
videos tailored to my vehicle guided me to easy installation of both hitch and wiring harness.



by:

I had a great transaction with etrailer and not knowing exactly what I needed, they helped to purchase the right hitch for my Honda Pilot. It helped so much to have a company help and guide me in this purchase. I trust their knowledge and love the customer service they provided.



by: 11/17/2023

Description says hitch will fit 18in spare tire. Not 18 inch wheel with tire (that comes on vehicle) but a 18 inch full diameter of tire so my spare does not fit. Just a little confusing because Honda recommends full size spare when towing, which is odd, that would be the reason I bought the hitch in the first place, but the spare did not fit. Oh and don,t get the curt trailering wire because that lasted 5 days.



by:

I was able to install the hitch I ordered, the wiring harness and the bracket ALL while listening to Cleveland and Tampa in the wildcard playoffs, even before the extra innings!
The instructional videos online were thorough and I had no questions. All works as required! Iā€™ll highly recommend etrailer to everyone. Thanks again for the fine craftsmanship of your hitches and the accessories.



by:
2022 Honda Pilot

The wire harness was packaged in a box and inside a larger box containing the trailer hitch that I ordered. Both boxes were damaged and somehow the wire harness was removed from it's own box and laying inside the hitch box. I did not notice any damage and haven't installed yet to see if the harness is working properly. I would strongly suggest packing the smaller items in a separate box to eliminate this issue. Ordering, delivery, and communication were outstanding from etrailer.

Wire harness is working fine. I have connected to multiple trailers and all lighting & brake lights work well.



by:

I installed the wiring harness, brackets, and tow receiver 12 months ago. This was a simple job to do. The video tutorial made it even simpler. Everything works as described. I only HATE the plates that hold the harness under the car (already rusting), I had to bend one 90 degrees to make it work and the harness falls out of the other plate when whenever I use it (see photo).
Harness - Perfect
Receiver - Perfect
Plate - 0 stars

Overall I like it and I would recommend their products. Please fix this issue.

2016 Honda Pilot

Great harness and it looks good with the bracket to keep it in place. My only problem was being unable to locate the back up sensor wiring to connect to the harness. Iā€™ve watched your videos but none of them include locating and connecting the ā€œblueā€ wire harness. I dug around and followed my truckā€™s sensor wire but I was unable to locate the connector. My guess is itā€™s buried behind the jack holder which makes it inaccessible unless you remove the entire panel, not just peel it back like in the videos.

Thank you for your review. If you cannot locate where to plug the blue wire in I would go to your local dealership. They will be able to pinpoint where it would be at. Here is an expert answer that can be of some help:

Worked out perfectly for our new Honda Pilot.

Jim

Everything is working out great!



by:
Honda Pilot

16 Pilot Touring model. Truly plug-and-play. I opted to NOT run it out of the bottom. Instead, I run in out the back hatch when needed (I only tow a few times a year). I did have a problem with the hatch thinking it was stuck on something, but I move the wiring loom a bit and just have the flat wire at the hatch opening. Then I can put it all back behind the small door on the left side of the 'smugglers hold' and it is gone from sight.

2022 Honda Pilot

Plug and play. Outstanding video instru ctions!



by:
Honda Pilot

This worked perfectly in our 2021 Honda Pilot. Installation was pretty easy with a video on Youtube.



by:

Worked perfectly once installed. Missing one star because of the installation process. I had to make a few phone calls over a harness plug that didn't seem to go anywhere in my pilot. I got varying answers. One was fortunately correct and then no issues since installed 1 year ago by myself.



by:
2017 Honda Pilot

I recently purchased this wire harness, and I couldnā€™t be more impressed with its simplicity and efficiency. Installing it was a breeze, thanks to the clear instructions provided, and the accompanying video tutorial was incredibly helpful.

The harness itself is well-made and durable, ensuring a reliable connection between my vehicle and trailer. The plug-and-play design made the installation process straightforward, even for someone with limited experience like myself.

What really stood out to me was the quality of the instructional video. It walked me through each step of the installation process, providing visual aids that made it easy to follow along. This attention to detail significantly reduced the likelihood of errors and made the entire experience stress-free.

Overall, I highly recommend this wire harness to anyone in need of a reliable solution for towing. Its user-friendly design and informative video tutorial make it a standout choice in the market.



by:
2022 Honda Pilot

Wire harness works great. Name of product is misleading as it is for installation in a vehicle that does not have a factory tow package. The how-to video is amateurish with several errors in it. Like all how-to videos this one omits the single most difficult procedure, in this case, releasing the car's white electrical connector so it becomes accessible.

Etrailer Expert

Sierra K.

1/21/2022

This wiring harness plugs directly into OEM tow package wiring connector so that no cutting or splicing is required. Since you released your white electrical connector, you have a factory tow package. If you did not have a factory tow package then you would need a product named hard wire application.

Podman

1/24/2023

As I mentioned in the original review, the name of the product is misleading. Think about it. If my vehicle had the factory tow package it would already have a trailer wire harness installed and there would be no need for this part. One years since installation and everything is working fine as expected. I would buy again.



by:
2021 Honda Pilot

Great product $800 cheaper than what the dealer wanted to charge me. Was easy to install with the video on the trailer hitch and wiring harness. Was stated that the foot sensor for the tailgate may not work with this trailer hitch but on the 2021 pilot AWD the sensor is offset so it still works. work Sensor is located at parked in pic. I think the sensor is only offset on the AWD models.



by:

With the help of etrailer video, I was able to easily install the wire harness! Thanks etrailer!

Still working perfectly

by:

I received my package with everything I ordered and the hitch receiver seems to be well built thankfully. However when I received the package it was severely damaged and open. It appears that no packing was added to the box to take up the dead space around the hitch. I would hope in the future etrailer would do something to remedy this.



by:

Delivered sooner than expected. Easy installment... Just jacked up the rear and slid into place... attached with 6 bolts perfect fit. My wife and I did it in about 25 mins.



by:
2021 Honda Pilot

Exact part I needed. Good price. Fast shipping Highly recommended



by:

Very quick and easy shopping experience, shipping was exceptionally fast. The description of the product was spot on, and all parts were installed with ease.



by:

I purchased this trailer hitch receiver, light wiring harness and hitch and ball. Everything has worked the way it was supposed to and was super easy to install. I am very happy with the prices and the product!



by:

This is amazing. The video was extremely helpful. Lucky for me, I didnā€™t have to drill any holes to insert the wiring for the lighting harness. This system is perfect!
