  • Tekonsha

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.


  • Provides a 7-way, blade-style 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 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
    • Powered module connects directly to avoid overloading your vehicle's electrical system
  • Supplies required fuses to activate functions
  • Constructed of 16-gauge bonded wire


  • Maximum amperage
    • Stop/Turn lights: 4.2 amps per circuit
    • Tail lights: 12 amps per circuit
  • 1-Year limited warranty


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.

T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector - 118291

Average Customer Rating:  4.5 out of 5 stars   (37 Customer Reviews)

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.


Good wire harness. The YouTube Etrailer video and the paper directions are slightly different. Look at both. Bought a bracket and was short 2 screws. Etrailer did reimburse me the difference in the price change within the 30 days of the sale. Thank you


Wiring kit is good and almost installed as expected. This is not etrailer’s fault but the self tapping screw supplied for the ground wire had a smaller head than the hole in the wire end attachment. Of course I did not have a larger self tapping screw or a washer that would fit which necessitated a trip to get a washer that would work.

You must have received the wrong screw. Customer Service will email you.

Honda Passport

Easy to put together and YouTube video helped take apart the back end of the car and wire it properly. Only thing I didn’t realize was I needed an extra fuse. My car is 2021 passport so I needed one more.

2021 Honda Pilot

The white wire wouldn't lock into the plug, but the gray plastic clip will hold it in place. I checked it with a meter and it works fine.


Was extremely easy to do after watching video provided on website.


Multiple parts missing from order and very difficult to speak with a person when calling.
Never had issues with etrailer in the past.

I will definitely have our customer service team reach out to you. We will have this taken care of for you.
-- Etrailer Expert Jenny N - 06/20/2022


Very well built kit and easy to install and all the connectors fit perfectly. The runner grommet worked very well transitioning from inside to outside. Be sure to also order a mounting bracket for the 7-pin plug. I didn’t and had to get one from the local hardware store.


The parts look good. The wiring harness box was opened up in the box that the hitch came in but I did find all the parts except the instructions. I did find the instructions online


Zip ties a little short to tie to hitch. Had to use much longer ones from my stash. The ground screw too small whole screw fits through ring on ground wire


This harness made installation a breeze! Matched the factory pigtail, the seal through the body was perfect,and it had plenty of length to tie it out of the way and reach the proper location perfectly.


This cable connects to your car's connector to supply everything you need for trailer lights. Set up is quite easy. Thanks eTrailer.

This cable works like factory equipment.
Phillip P - 09/25/2021


Holes did not match up


Everything you need with straight forward instructions. Couldn’t have gone better.


The harness was pretty easy to install once you get the body panels off. Its plug and play so no wires to cut and splice. The only thing that happened was after 6 months I lost lights on the left side of my trailer. I contacted customer service and they told me chech the wiring before and after the control box to make sure it wasnt the car. Sure enough, it was the control box. Customer service resolved the issue immediately by sending me a new one. etrailer is second to none.

2019 Honda Passport

Excellent so far. I just installed the hitch on my 2019 Honda Passport. The video tutorials were very easy to follow. I'm very happy that I decided to install it myself.


With the right components, tools and a few [online] videos, installing this wiring harness was a piece of cake.

I am very impressed with the customer support we received from etrailer. Nicole, who took the order, was fantastic and reassuring; she even checked stock while I was on the phone to make sure the hitch and wiring we needed was in stock and available. We were against a tight timeline and paid for expedited shipping - but the estimated delivery date was only a day before our departure. We received an email our hitch and wiring harness were shipped in less than 24 hours, and both came safely packaged day later, giving us plenty of time to install it before our trip. So pleased! Thank you

Honda Passport

This is a very high quality harness. Very easy to install, came with every thing you need. Installed this on a new 2020 Honda Passport. Took me about 30 minutes to install and that was taking my time. I ordered this with the receiver hitch and the bracket for the 7-pin plug that came with the harness. Everything was shipped for free and arrived in 4 days. Anyone with basic tools and knowledge can install this. Ordering this and installing it myself saved me over $1,300 compared to letting the dealership do it. I would highly recommend this to anyone.


The original order for the Curt custom fit harness was placed after several discussions with but despite assurances, it only partially worked and is being returned this week. After several conversations with Shanna S. at, I ordered the better Tekonsha trailer harness and it works perfectly. Had I talked to her first, it would have saved both of us much time and expense.


Fit as described. Have not used with the trailer yet. Prompt delivery. Thank you!


I purchased a hitch and this wiring harness for a 2019 Honda Passport. Delivery was fast and both products fit perfectly with easy install. Customer service at etrailer is the best I've ever dealt with. I highly recommend to anyone looking for accessories.

2021 Honda Passport

Fast shipping and good instructions for installation. ETrailer is the best !


Looks good waiting to hook it up

  • Troubleshooting Tekonsha T-One Vehicle Wiring Harness Ground Wire Not Fitting In 7-Way Connector
    It sounds like you're having trouble fitting the ground wire in the back of the 7-way connector on your T-One Vehicle Wiring Harness # 118291. This is larger than the other wires so you need to make sure you are inserting the wire in the correct spot. See the diagram below. The ground wire fits in the larger hole on the right side marked "B." There is only one orientation for the wires to fit, and once inserted they will lock in place. It should not require a lot of pressure so if you're...

  • Easy to Install Brake Controller for 2020 Honda Passport
    If you already have a 7-pin connector on the back of your Passport then, by far, the easist solution is the Curt # C51180 Echo Wireless Brake Controller. Simply plug one side into your tow vehicle 7-pin connector and plug your trailer into the other end. If you do not have a 7-pin connector you will have to start by installing the Tekonsha # 118291 wiring harness. This will easily install and provide the connections you need for trailer lighting and brakes. Fortunately the Honda has...

  • 7-Way and Brake Controller for 2021 Honda Passport Towing Camper with Brakes
    To tow a trailer with brakes with your 2021 Honda Passport you'd first need to install the 7-way kit part # 118291 which is the same connector as your Flagstaff 228BHSE. Then for a brake controller we have the very easy solution of the Curt Echo Mobile wireless brake controller # C51180 which once plugged into an active 7-way and synced to a smart phone is read to tow without any additional wiring.

  • Does the Draw-tite Hitch for Honda Passports 76290 Come with a Wiring Harness
    I have a solution for you, but the Draw-Tite # 76290 does not come with wiring; this is fairly commonplace since not everyone will need a trailer wiring harness with their hitch. With that said, I recommend using the Tekonsha # 118809, which is a confirmed fit on the 2019-2021 Honda Passport (the same as the Draw-Tite 76290). This provides you with a 4 way trailer connector that has a powered converter to help protect your vehicle's electronics from shorts and backfeeds on the trailer....

I've confirmed with the manufacturer that this bracket is designed for electrical connections to be mounted to the frame of the hitch, such as the one for the 7-way that is included in the Tekonsha T-One # 118291.

    It is pretty easy to install a trailer brake controller like the Curt Echo Wireless # C51180 on your 2021 Honda Passport.

    For the best fit and safety the custom fit hitches by Curt # C13421 and Draw-Tite # 76290 are your best options for your 2021 Honda Passport. These hitches are custom fit so that you will not have to drill into your frame or modify any of your bodywork. I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76290 as it has the tabs mounted to add the 7-way directly to the receiver.

  • Trailer Hitch For 2020 Honda Passport With Best Finish
    Both the Curt # C13421 and Draw-Tite # 76290 Class III hitches are confirmed for a 2020 Honda Passport. Both hitches weigh roughly 42 lbs. We've found that the powder coat finish Curt uses to have a slight edge over that of the Draw-Tite, so that's what I'd recommend. Keep in mind, that even though the hitch uses a quality powder coat finish, the hitch will occupy a spot on the vehicle where it will be subject to much abuse. It's recommended to give the hitch a quick look-over once or...

  • Recommended Trailer Wiring To Add 7-way to 2020 Honda Passport
    Maria, It is possible to put a 7-way on the 2020 Honda Passport with factory tow package with Tekonsha wiring part # 118291. This wiring harness will plug into the factory OEM port under the bumper and give you a 7-Way plug at the rear of your Passport. It includes all of the required fuses to activate the tow package. You will need the mounting bracket part # PK12711U and Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Bracket - Long part # C57202 to mount the 7-way.

It features a black powder coat finish with an e-coat base as well as a limited lifetime warranty. This hitch has a maximum gross trailer weight of 6,000 lbs and tongue weight of 900 lbs.

    Neither the Curt # C13421 or Draw-Tite # 76290 trailer hitch receivers you were looking at for your 2021 Honda Passport will mount through the bumper like the factory hitch would. These receivers mount just under the bumper and leave just the receiver itself visible once installed. If you are alright with that then I recommend going with the # C13421 as the absolute max possible towing capacity of your Passport based on its options is 5,000lbs which lines up with the 750lb tongue weight...

    To tow a trailer with your 2022 Honda Passport Sport you're going to need a trailer hitch receiver, trailer wiring harness, and a ball mount.

    A taillight converter combines 3 circuits, left turn signal, right turn signal and brake lamps into two circuits.

This is necessary because the trailer uses a 2 wire system instead of the 3 wire system used on the tow vehicle. I'd recommend the Tekonsha # 118291. The Passport is prewired for a brake controller so installation will be a plug and play proposition. For a fairly...

The body of the controller installs under the dash where it's out of sight (also where you won't bang your knee on it). You'd adjust the controller via the control knob, which can be mounted anywhere within the driver's reach.
