Installation
This custom-fit T-connector plugs into your vehicle's wiring harness. The connection point for the T-connector is located towards the center of your vehicle on the back wall of the cab. The converter plugs into the gray 12-pin tow plug. 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 4-way flat connector will be stowed beneath your vehicle, under the bumper. Secure the connector with the included cable ties.
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.
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 draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.Just finished installing the T-One Trailer connector on my 2017 Honda Ridgeline RTL-T. Installation was not too difficult. Instructions were sparse with respect to exactly how to locate and access the plug on the back firewall. Also the instructions on how to remove the cover on the plug under the rear bumper were not very helpful. A short video on these tricky things would help immensely. How and where to attach zip ties or sticky tape is not needed. Beyond that I am very pleased with my trailer connector. 561181
The four wire trailer kit installed successfully on a 2019 Honda Ridgeline RTL-T. Installing the black box module is easy once Honda's connector is located behind the driver's side rear seat. Carefully remove plastic panel (near floor) next to where seat belts bolt to frame. Panel has two flexible tabs near top - one on either side of the seat belts - that must be carefully moved a bit to release the panel at top. Check other reviews for photos on locating the cable (it's the thicker one) and connector that plugs into black box. The connector will be tucked behind some thin insulation material. Gently pull it down to expose connector. Its cable shroud is tied to back wall at one point but there's enough slack to connect to module. Secure the module to your taste, install three fuses under hood, and finally connect up trailer cable (very easy). Don't forget to grab the boat and trailer then head to the lake. The kit has high quality parts. 643239
The product is high quality and the instructions are very good. It took me about an hour to install and worked perfectly when complete. I would recommend it. The only difficult part was finding where Honda hid the gray plug for the powered converter module behind the back seat and behind the sound deadening material.. Be patient and persistent and you will find it. etrailer is always my “go-to” supplier for anything towing related. 633409
Gary - 04/20/2020SO far very poor instructions. I mean really the photos do not match my truck, they are not clear at all. They make it sound so simple, but I still cannot find the harness connector in the back seat of my brand new truck. 595987

Good sale , good item. 5 stars across the board. Item was plug and play. Really fits perfect. Super fast shipping. 790101
The trailer turn signal control module kit worked perfectly when installed and still does a year later. Honda wanted over $200 for the kit. E-trailer's kit was less than $40 dollars. Couldn't be happier! 785563
No problem at all other than having to remove to back seat only to find out it was right where the instructions said it was. 771115
Perfect fit!Great price!Good instructions.Wish that Honda could have made it easier to get to the hidden wiring though. 765617
Product worked just fine after I figured out how to get the cover off of the connector at the back of the truck. I did use information from the etrailer website to conquer it. 739611
The wiring at rear hitch was easy and simple. Finding the connection behind the rear seat involved removing the entire seat bottom and back to make a simple connection of the converter. Once that was done the real problem came with trying to follow the fuse placements. After consulting the we then owners manual , was able to figure it out 703320
Great product. Horrendous instructions. The instructions have one picture to show where to mount the module. In black and white! I could not find the connector for the module for my vehicle. Called support two separate times and could not find it. Finally through another review there was more detailed information. There really needs to be 1st hand knowledge on how to install these for all different models. I figured since it was a for a honda it would show me exactly where to go. But all in all figured it out. Works fine. UPDATE the instructions with color DETAILED pictures! 669808
Parts worked great and a lot less than the $400 Honda wanted to charge. Parts fit as advertised. I'm very satisfied. 651392
The support that eTrailer provides for their products is unequaled. Shipping is quick. Thanks, eTrailer. - Ed 635180
Edwin - 04/26/2020The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118778 is compatible with 2017 - 2020 Honda Ridgeline all styles including the Sport. The black box module will plug into the 12 pin connector. First, remove the rear seat trim panel to access the connector area. The 12 pin vehicle tow plug connector will be located near the green relays on the driver’s side. The square plug of the towing harness will plug into the factory gray plug shown in the instructions with an arrow pointing to it. There is a cap on this plug that needs to be removed by sliding it rearwards. It has locking tabs as well so press down on those and that should remove the protective cap carefully.

seems to be a good product at a good price....however...your 'install video' says A) open the rear door B) locate the receptacle and plug in the device..... There is a lot of unexplained hard work to get from A to B....like remove the entire back seat....etc.....at least 1/2 hour each way....... 577741
