  • Tekonsha

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.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes Modulite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to avoid overloading your vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 4.2 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


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   (282 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.


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.

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.

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.
-- Etrailer Expert Sierra K - 01/21/2022
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.
Podman - 01/24/2023


I really found that installing the unit was somewhat easy. I would recommend etrailer to anyone looking to install a hitch.


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.

2019 Honda Pilot

Box came damaged is an understatement (see photos). I'm hoping none of the bolts were lost or the wiring kit was damaged. But it is a bulky item and it's typical for damage to box. Off hand, I'm thinking everything is ok.


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! I’ll highly recommend etrailer to everyone. Thanks again for the fine craftsmanship of your hitches and the accessories.

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. I’ve watched your videos but none of them include locating and connecting the “blue” wire harness. I dug around and followed my truck’s sensor wire but I was unable to locate the connector. My guess is it’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:
-- Etrailer Expert Sierra K - 06/28/2021


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.

2022 Honda Pilot

All items were received in good condition with clear instructions for installation. The videos on etrailer website were especially helpful. Everything worked perfectly after install. Since the factory installed the back up sensor, there was nowhere to plug in the blue wire.


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

Still working perfectly

Works perfectly!
Brad - 08/30/2021


Fast shipping and hitch installed easy and was extremely well built! Great install videos too!


the T one was perfect, but the instructions, were very small print and photos, and were not totally correct. you have to remove the rear interior panel partly for a 2022 honda pilot, to get to the main connector , not difficult at all, but the direction did not mention that.

2022 Honda Pilot

Install was quick and removing plastic was the hardest part. Video was very helpful for installation.


Came in quick,easy install. Didn’t have to fight with it at all.Great in use now for 6 months

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.

I will have our Customer Service team reach out to you.

2016 Honda Pilot

E-trailer's hitch for our 2016 Honda Pilot Touring fit perfect, as described. No problem installing, except that the bolts too a LOT of leverage to crank fully tight. The e-trailer video was a savior!


Always very happy with e trailer they send me correct items videos that make it easy to install and fast shipments Christy very helpful and knows her stuff very happy with her customer service I think the best way to describe e trailer it trailer hitch for dummies lmao cause it’s so easy to do thanks Christy


Great product and loved the installation videos provided by the site. I definitely recommend etrailer and I’m very happy with my purchase.


I am very pleased with the hitch and wiring harness that I purchased. The hitch is well constructed and the installation instructions for both the hitch and the wiring harness were clear and accurate.


Fast delivery and a top quality hitch. This hitch was a breeze to install, had the hitch bolted to the car in less than 20 minutes. Complete job with wiring harness in less than 2 hours. (Took my Time)
Highly recommended

2017 Honda Pilot

I went to an auto electric shop to have trailer wires installed. They wanted about $400.00 to install an adapter and tail. I thought the job could be done in a couple of hours and felt the charge was more than the work was worth. I found the part at for $72.00 and installed it myself in 45 minutes. The job was simple and easy and I saved a ton of money.

2021 Honda Pilot

Shipping was quick and install was very easy watched the videos on installing the hitch and wiring harness both were very easy install.


Easy installation.


Works well, easy to install. A little frustration with the extra blue wire that was to defeat backup beeper, which as it turned out I didn't need but waisted a lot of time trying to figure out we it was supposed to plug in .

2021 Honda Pilot

I received exactly the article that was ordered in a timely fashion and all components were contained in packaging, I installed on my vehicle exactly as video instructions. I tested wiring and all worked as required. This again was a good experience in ordering, delivery, and instructions on specific installation. Thank you

It has worked perfectly, and continues today.

  • Do Interior Panels of 2017 Honda Pilot Need to Be Removed to Install Trailer Wiring
    In our install videos sometimes we have to go a bit further with the steps to be able to show everything. We'll sometimes take panels off so that we can show better where the location of a connector may be. This gives better access for our cameras to see what's going on. If you can grab the connector on your 2017 Honda Pilot to install the # 118760 without taking the panel off you'd be just fine.

  • Installation of Tekonsha 118760 Wiring Harness for Factory Tow Package on 2016 Honda Pilot
    On your 2016 Honda Pilot, the blue wire and quick connect of harness # 118760 should have a mating quick connect in the rear cargo area if you have the backup sensors. If you don't have the backup sensors, then this wire and connector are simply stored out of the way and left disconnected. I've attached the installation instructions to assist. If you have the sensors and yet cannot locate the connection harness, then you will need to trace the wires of the sensors from the sensor itself...

  • Troubleshooting Wiring Harness 118760 Installation in 2018 Honda Pilot
    I am sorry your installation of wiring harness # 118760 in your 2018 Honda Pilot was a challenge, and also that it is not functioning. The first thing to check before you un-install the harness is that the ground ring terminal is tightly affixed to a clean metal surface. A good ground is essential for any wiring harness to function. You might even sand off that point to expose bare metal which will give you the best connection. The other thing to check is the installation of the included...

    The Tekonsha 4-pole Wiring Harness # 118760 fits your 2012 Honda Pilot that has the factory tow package. The connector with the single blue wire plugs in to the mating vehicle connector, next to the main tow package connector behind the driver-side trim panel, but only if the vehicle has the back up sensors. If it does not then that wire/connector is not used. The written instructions for this item are linked for you.

  • Tekonsha 4-Pole Wiring Harnesses for 2017 Honda Pilot
    Tekonsha 4-pole wiring harness kit # 118760 is a fit for the 2016 through 2018 Honda Pilot. Part 118679 is now discontinued. The harness # 118760 is the new version that includes a second connector with a blue wire that should be connected to the mating plug on Pilots that have the backup sensors. If you use this harness on a Pilot without the sensors then that second connector with the blue wire simply is not used. I confirmed the above information with my contact at Tekonsha. Both kits...

  • Can Ground Wire On T-One Trailer Wiring Harness Be Secured In Place With Electrical Tape
    One of the biggest issues customers run into is when the ground wire(white wire) is not secured very well. It can cause unpredictable results that range from some lights not working to none of the lights working, and can happen at the worst time. The ground wire needs to be secured to a clean, bare metal surface to provide the ground for the harness and to ensure it works properly. I recommend finding a nearby screw that is already fastened on the vehicle. You can take it out, and then...

  • Help Locating Tow Package Port/Plug on a 2016 Honda Pilot
    The tow package port/plug for a 2016 Honda Pilot is located behind the rear driver side trim panel in the hatch. If you have trouble locating the port you may need to remove a few things and pry the panel away from the body so you can get a better view of the inside. That said, I was able to find this plug by simply removing the access door on the panel instead of prying the panel away but this may be different for each vehicle. There are some models that the port/plug is easier to find...

  • Trailer Wiring Harness for 2018 Honda Pilot with Reverse Sensors
    Since your 2018 Honda Pilot features the factory reverse sensors you will want to go with the Tekonsha T-One Wiring Kit # 118760. As you mentioned in your question, this particular harness includes an additional connector that is only used on Pilots that are equipped with these sensors, and it allows them to continue working as normal with the harness plugged in and in use. The Curt alternative does not include this additional provision so it won't work well on your vehicle.

  • 2016 Honda Pilot Back-Up Sensor Plug for Installation of Wiring Harness
    I don't have any advice, exactly, but the back-up sensor plug that mates with the T-One Vehicle Wiring Harness # 118760 on your 2016 Honda Pilot should be directly next to the plug for the main harness. Occasionally this can be pretty difficult to find and it could be jammed back pretty far or possibly taped to the side so the best I can offer is to keep digging and you should be able to find it assuming you have these accessory sensors on your Pilot.

    Since the # 118760 that you installed is only for trailer lighting only the one fuse is needed to be installed.

Most likely what's the issue is the ground wire of this harness. The white wire of it needs to connect to a clean metal surface so that the harness has a proper ground and will function properly.
