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.

Thats great! So glad our video was helpful. Thanks for letting us know!
Easy plug and play with plenty of wire to get down to the 7 way. I was able to attach to a factory ground like one of the videos showed. It's been installed for one year with no issues.
Install took about an hour. Youtube video helped alot. Haven't had a chance to connect my trailer yet.
Was extremely easy to do after watching video provided on website.

Still works like the day I put it on the vechicle.
The wiring kit did not come with a bracket for bumper attachment.
Good video instructions, fairly easy install and well built wire harness.
Perfect fit. Excellent quality and easy installation.
Easy installation, same as the factory factory installation documentation and photos. Recommend watching the 2019 installation on the etrailer website at My 2023 Passport had a large bolt on the frame of the cubby box rear floor support, so I used it for the ground wire. I also wanted easy access to the fuse if needed without removing the cubby box so I mounted the module on the driver side rear internal reinforcement where the storage box is. Which may for easy installation with no drilling, used the double sided tape and zip ties. Now if I need to check the fuse all I have to do is remove the storage box. Hope I never have to but you never now. The one time I had this problem prior on another vehicle it was caused by bad trailer wiring on a back road at night and raining.
Video installation instructions were extremely helpful. Everything was plug and play once one had gained access to the hidden factory connectors.
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.
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.
Easy to follow video on how to install, it took less than an hour (as long as you have the right tools).
Really well made kit that fit like factory and had no issues installing.
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 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.
The original order for the Curt custom fit harness was placed after several discussions with etrailer.com but despite assurances, it only partially worked and is being returned this week. After several conversations with Shanna S. at etrailer.com, 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.
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.
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 etraler.com.
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.
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
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.
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
Plug n play. Fit my Passport perfectly.
