  • Trailer Hitch Wiring
  • Tekonsha

Installation

This custom-fit T-connector plugs into your vehicle's wiring harness. The connection point for the 7-way harness 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 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 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.

  • Help Locating the 12 Pin Tow Plug on a 2017 Honda Ridgeline
    I called Tekonsha about the T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector part # 118288 for your 2017 Honda Ridgeline and they have not had any instances in which the tow package wiring was not present. They stated all of these trucks came with the factory tow package wiring regardless of options.

  • Trailer Wiring Harness Recommendation for 2019 Honda Ridgeline
    For your 2019 Honda Ridgeline the trailer wiring harness I recommend is the Tekonsha part # 118288 if you need a 7-way or part # 118778 for if you need a 4-way. These are the best wiring harness solutions as the Tekonsha brand is the most reliable option currently available due to their higher quality converter boxes. If your trailer has a 7-way and brakes you'll need a brake controller to activate them for that our best option is the P3 # 90195. This is a proportional brake controller...

  • No Power to Taillight Pin on Trailer
    If you have no power to the taillight pin with the T-Connector Vehicle Wiring Harness # 118288 then the issue is almost certainly that you have a blown fuse on your 2019 Honda Ridgeline. What you will need to do is check you owner's manual to find the fuse and replace it, which should remedy the issue. The only other thing that might be happening is a wire leading to that pin is somehow damaged, so that would be the other thing to look for. I have added links to a couple trailer...

  • Locating Factory 12 Pin Connector on 2019 Honda Ridgeline to Install Tekonsha Harness
    The factory 12-pin plug where the Tekonsha Harness # 118288 will plug in on your 2019 Honda Ridgeline is located towards the center of the vehicle on the back wall of the cab. To access the plug you will open the rear driver side door and fold the bottom rear seat up into the upright position. Then remove the seat trim panel and the plug should be to the left of the green factory relays.

  • Does Rear Seat Need to be Removed to Install 7-Way Wiring Harness on 2019 Honda Ridgeline
    So in regards to removing the rear seat, that does not have to be done on your 2019 Honda Ridgeline to install the T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # 118288. Per the directions you will need to remove the rear seat trim panel, which you can do with the Powerbuilt Trim Pad Remover # ALL648544. As for the modules, they are different so you will need to use the one that comes with the Wiring Harness # 118288.

  • Brake Controller Recommendation for 2019 Honda Ridgeline
    First let's get your 2019 Honda Ridgeline setup for a 7-way and brake controller. It sounds like you might have a 7-way already installed, but if you didn't the correct kit would be the part # 118288 which is a confirmed fit for your vehicle. The brake controller I recommend is the P3 part # 90195 that you referenced. This is the best performing controller and also the most advanced so it will do the best job for you overall. It has a screen that can display full words, the ability to save...

  • Installation of Wiring for a Leer Camper Shell on 2018 Honda Ridgeline
    It sounds like the dealer messed with your factory wiring harness and you want to replace it with the T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector # 118288. The correct way to run the wires is to connect the dome light to the 12V power wire either directly coming from your battery using a circuit breaker or splicing into your 12V wire at the 1 o'clock position at your bumper. If you want to run a specific wire, you will use # 16-1-1 sold by the foot and use circuit...

  • How Easy is It to Install Curt Echo Mobile Trailer Brake Controller
    The really great thing about the Curt Echo part # C51180 is that it only requires a functional 7-way on the vehicle and a smart phone and it's good to go. So you'd just need to pair this to your phone after plugging it into the 7-way and you'd be ready to tow. You would not need to use the brake controller port on your 2017 Honda Ridgeline at all. I attached a review video for more info on this as well. If you were in need of a 7-way for your Ridgeline the Tekonsha kit part # 118288...

  • Changing to 4-Way and 7-Way Connector on a 2017 Honda Ridgeline
    Since your 2017 Honda Ridgeline has the factory 7-way connector on it you should have a wiring harness that has the standard to package plug. It's the harness that plugs into the back of the 7-way connector and looks like the picture I attached. If this is how your 7-way connects then you can simply unplug the factory connector and replace it with part # HM40950 that has both a 4-way and a 7-way connector in one. If your factory 7-way plugs in in some other fashion let me know. Send...

  • Recommended 4-Way Flat Wiring Harness for a 2019 Honda Ridgeline
    If you are looking for only a 4-Way Flat connector for your 2019 Honda Ridgeline then I recommend the Tekonsha T-One # 118778 because it has higher amp ratings than the Curt option and we have found the Tekonsha wiring units to be the most reliable out there. This connector gives you the basic lighting functions that you need for a smaller trailer and can be mounted using the Tow Ready # 18144 and a no-drill bracket like part # 18140. Since you have a pickup I do recommend installing...

  • Is Powered Converter Needed for Installing Trailer Wiring on a 2019 Honda Ridgeline
    The powered converter is what will send the actual power to the trailer connector so you will need to install it on your 2019 Honda Ridgeline whether you're installing the 4-Way flat or the 7-Way connector. I recommend going with the Tekonsha kits, 4-Way Part # 118778 or 7-Way Part # 118288, simply because we have found them to be the most reliable option. I'm attaching links to the installation instructions as well as our ball mount selection and a helpful article about choosing a ball...
