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.

2021 Honda Pilot

Ground (White) wire was too short to reach a screw in the metal plate in the rear compartment of our 2021 Pilot, had to remove the electrical tape and zip tie so I could push the rubber grommet further down the wire under the car that way there was more wire length available in the rear compartment. The 7 blade pin adapter was faulty, one of the wire connectors would not clip in, I had to use another adapter to finish the install.

For this harness, it is definitely a trickier install as there is not a lot of room to work in. I did find that others have had the same issue with the ground wire. I recommend taking a look at the video install that we have on a 2020 Honda Pilot starting at time stamp 11:10 to see how we handled it. As for the 7 way adapter I will have our Customer Service team reach out to see what we can do for you.



by:

I have ordered from etrailer several times and have never been disappointed. Products are always top notch, prices are good and video instructions have been spot on. Communication is great. I would not hesitate to order from etrail again.

2016 Honda Pilot

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.



by:

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.



by:
2016 Honda Pilot

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.



by:
2017 Honda Pilot

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



by:
2016 Honda Pilot

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.



by:

I wasn’t sure how the wiring harness would work. I had never done anything like that before. I followed the instructions, and everything worked perfectly.



by:

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.



by:

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.



by:
2010 Honda Element

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.



by:

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.



by:

Very straightforward installation....just follow the video.



by:

I 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.

No problems with the trailer wiring harness so far and dont anticipate any. Great product!



by:
2021 Honda Pilot

Instructions were easy to understand and the video online helped as well. Would highly recommend this wiring kit over others. Top notch.



by:

Perfect fit. Easy to install. Supported by a great instructional video.



by:

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.

Thank you Chad, to bad E-trailer did not know this, and it works. There FAQ and tech support sent me on a wild goose chase, even say its on the passenger side of the car. I could find nothing either side. Etrailer please correct your miss-information, cost me hours in the hot sun!

we have a few cases where the customer says that the car has a backup sensor but the manufacturer did not include the connecter. In these cases the blue wire was not used and did not affect the function.

Excellent plug and play harness. The instructions video was extremely helpful too. I used this harness with the Honda hitch for an integrated install.



by:

Perfect very useful to any carriers with light I installed to my car



by:

Still a great product. I have used unit quite a bit over the past year and there have been no problems at all.



by:

Not completely installed because I expected a mounting bracket would be included but isn't. So I have to wait until the bracket arrives to test it. Appears great otherwise. Have purchased before from etrailer and have always been pleased.



by:
2016 Honda Pilot

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.

Ron

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



by:

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.

Peter

Still just fine!



by:
2011 Toyota Venza

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.

Still working great, likely to last a long time.

  • Where it the Back-Up Sensor Plug on 2020 Honda Pilot for Installing Tekonsha 118286 Harness
    I can see why the instructions might be confusing and unfortunately we don't currently have an installation video of the # 118286 on a Honda Pilot with the backup sensor available, but I can help you. If you check out image D on the instructions page it shows where you should look to plug into the backup sensor. This plug is located behind the passenger side access panel. I've linked a photo of the instructions that shows this in better detail.

  • Is the 7-Way of the Tow Ready Trailer Harness for 2016 Honda Pilot Same as Honda Trailer Connector
    The 7-way that comes with the # 118286 is a standard 7-way design that is different from the Honda 7-way harness for your vehicle. This uses a 4-bolt mounting bracket whereas the one that comes from Honda uses a bracket for the 7-way that uses 2 bolts on the bottom of it. This 7-way will still work and could potentially still fit in the cut out area of your Pilot but it may require modification. The one we offer will also be much less expensive.

  • Comparing the 7-Way Trailer Wiring Harnesses for a 2016 Honda Pilot
    Wiring harness # 118286 is meant as a replacement for the OEM 7-Way on a 2016 Honda Pilot or to upgrade the factory 4-Way to a 7-Way. Wiring harness # 118286 is similar with the difference being that it has a second connector that works with the backup sensor which allows that sensor to continue working. If the vehicle never had a trailer connector then go with 118286.

  • How to Install the Tekonsha 118286 on a 2021 Pilot with the Backup Sensor

  • Can the 12V Wire on 7-Way Power a Scooter Lift
    The answer to this will depend on your scooter lift. The 12V wire can be used to power your scooter lift but it will be limited by the fuse in your vehicle. From what I was able to find, this is a 30 Amp fuse in the 2019 Honda Pilot. I would double check the owner's manual just to make sure. As long as the only thing drawing power from the wire is the scooter lift, and the scooter lift does not use more than 30 Amps, you should be able to use it. If you exceed this you will blow the fuse.
