2020 Honda Fit - T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • Tekonsha

Quickly and easily install a 4-way trailer connector on your Honda Fit with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector
  • 1-Year limited warranty


This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.

T-One Connection Location Points Behind Tail Lights

Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.

Once installation is complete, the 4-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 4-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.

This kit was pretty easy to install, especially with the instructional videos on the site. It has held up very well over the past year, with absolutely no issues.

Another year in and still working great!
Nathan - 03/31/2022


Working with etrailer was great. I accidentally ordered the wrong drawbar for my hitch and they called me and fixed the order before sending it.
The hitch installation went of... without a hitch.
The only bummer was running the hot lead from the rear of the car to the front. It was kind of a royal pain.

2015 HondaFit

Order arrived quickly and the wire harness was easy to install. Staff at etrailer very helpful during the order process.

Have been using the wire harness on and off for a year on my Honda Fit. Most of the time the cables are tucked away by the spare wheel and I just pull them out, and connect to the battery, running the wire through the car when I need to hire a trailer. So far works great and is the perfect solution for me.
David C - 01/01/2022


The trailer hitch is just what I wanted and it works great. The wire harness makes the trailer lights work right off the battery. This keeps the lights from dimming when in use.


From the minute I discovered for my new trailer hitch needs, called them on the phone, got to a live person who helped me order every item I needed, was alerted that my items had been delivered, and opened the door to see a big cardboard box that actually was still in one piece, it was a topnotch experience. Talk about great customer!

I will attach a photo of my hitch once it's installed on July 29.


Got my hitch and lighting kit all hooked up. Instructions were clear. I will order again from etrailer when I need anything for my vehicles. Super fast shipping too!


Hitch installation was quick and easy. Works exactly as expected


Great Products. We were very happy with the quality of the parts and the help we received when we call customer support.

2018 HondaFit

Great product. Everything was there to complete the installation.

2018 HondaFit

Perfect fit as always! and the website gives you access to helpful tutorial videos that explain the product well, and show you how to install it.


Very Happy with this Product. It was exactly what we were looking for and arrived early. Thanks

  • Does Tekonsha Trailer Wiring Kit # 118767 Connect Directly to Vehicle Battery and will that Drain It
    The T-One Vehicle Wiring Harness with 4-Pole Flat # 118767 that you referenced does connect directly to the vehicle vehicle's positive battery post. This allows the trailer taillights to draw power directly from the vehicle battery and not from the vehicle taillight circuits. As long as the trailer lighting isn't active this will not drain the battery. Connections to a battery do not drain it. There has to be an amperage draw for the battery to drain in any way. Similar to how you don't...

  • Where Does the 4-Way Trailer Connector on a 2015 Honda Fit Store After Installation
    The 4-way trailer connector that fits your 2015 Honda Fit, part # 118767, actually stores outside the vehicle near the trailer hitch receiver. I've linked the install instructions for you. The harness plugs in behind both tail lights and then there is a power wire that needs to be run to the Fit's battery. To mount the connector near the hitch use the bracket # 18144, along with one of our no-drill brackets, # 18140 for the short one or # C57202 for the long one. On some vehicles the...

  • Trailer Hitch and Wiring Recommendation for 2018 Honda Fit
    Offically Honda states your 2018 Honda Fit is not rated for towing a trailer. Since people will still tow and there is a demand for a hitch for your vehicle we have a hitch like the Curt part # C11406 which is a confirmed fit as well as trailer wiring like # 118767. For a ball mount you'd need the part # C45521 as well.

  • Trailer Hitch, Wiring and Ball Mount Recommendation for 2015 Honda Fit
    For smaller, lighter-duty vehicles like your 2015 Honda Fit we only have Class I hitches like the Draw Tite part # 24920 that you referenced. I can't imagine a Class II hitch being available or useful for your vehicle as it wouldn't be able to tow 3,500 lbs regardless of what hitch is on it. We have trailer wiring as part # 118767 which would be a fantastic option confirmed as a fit. For a ball mount you'd then want the part # 36071 which is designed for this hitch and then for hitch balls...

  • Can Draw-Tite Trailer Hitch Receiver 24920 Be Used To Tow 4' x 6' Utility Trailer
    The Draw-Tite Sportframe Trailer Hitch Receiver # 24920 you were looking at for your 2016 Honda Fit would be fine for towing your 4' x 6' utility trailer as long as it does not exceed the 200lb tongue weight rating and 2000lb trailer weight rating of the trailer hitch receiver, or the towing capacity of your vehicle. All of the trailer hitch receivers made for your vehicle have the same 2000lb trailer weight rating, so I do recommend going with the # 24920 due to Draw-Tite hitches being...

Let's start with the trailer hitch and the best option in terms of quality and value is the Draw-Tite Trailer Hitch Receiver # 24920.

  • Trailer Hitch Recommendation for 2018 Honda Fit for Carrying Bike Rack
    Since the Curt Class I hitches require the use of a stabilizer strap when carrying a non-supported load like a bike rack the Draw Tite part # 24920 is the best hitch option for your 2018 Honda Fit. For trailer wiring you'd then want the part # 118767 which is a confirmed fit as well. For a ball mount part # 36071 and hitch ball part # 19256.

  • Routing 12 Volt Hot Lead to Battery on 2015 Honda Fit
    There are a number of options for routing the hot lead to the battery when installing the T-One Vehicle Wiring Harness # 118767 in your 2015 Honda Fit, but since this harness mounts outside the vehicle the best option is to run it along the exterior of the frame and up through the engine compartment. You can use Wire Loom # 7509-1 and Cable Ties # DW05726-10 for this. I have added a link to a help article on routing a hot lead to the engine which I strongly recommend checking out.

  • How Much Does the EcoHitch Hidden Trailer Receiver for 2015 Honda Fit Weigh
    The EcoHitch Hidden Trailer Hitch Receiver - Custom Fit - 2" # 306-X7273 weighs roughly 29-lbs, so it's really not going to add any more weight than a load of groceries or some personal cargo would in most cases. You're not going to see any type of improvement in handling or stiffening of the body though since it's not making any structural improvements to the vehicle frame. If you're going to be towing with this hitch you'll also need a wiring harness, ball mount, hitch ball, hitch pin...

  • Trailer Hitch Receiver and Wiring For a 2019 Honda Fit Sport
    Yes, the Draw-Tite Sportframe Trailer Hitch Receiver # 24920 will fit your 2019 Honda Fit with the Sport trim. This receiver is confirmed to fit all trim levels of your Fit. I do recommend installing a T-One Vehicle Wiring Harness # 118767 when you install the receiver. This 4-way flat connector will allow you to power Auxiliary Lights # C53201 with a hitch mounted accessory that impairs the view of your tail lights. It will also power the lights of most small trailers in the event you...

  • Will Adding a Trailer Hitch to my 2020 Honda Fit Sport Void the Warranty
    I'll start off by saying that the Magnuson-Moss warranty act that states, in part, that unless the part added actually causes a problem, then installation and use of the part will not void the warranty; so basically, adding a trailer hitch will not void the factory warranty on your vehicle as long as it's not the cause of a malfunction. With that said, I recommend using the Curt # C11406, which is confirmed on the 2020 Honda Fit-including the Sport models. This hitch will sit below the...

  • Can You Tow A Trailer With Class I Trailer Hitch Receiver On Honda Fit?
    The Curt Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # C11406 which is confirmed to fit the 2015 - 2020 Honda Fit has a tongue weight rating of 200lbs and a trailer weight rating of 2000lbs, though you will need to check the owner's manual of your vehicle and use the lower rating between the vehicle and hitch. You can use a Class I hitch for light duty towing, but I am not sure what the GVWR of the trailer you mentioned is so I recommend reaching out to Uhaul to find what ratings...

  • How Can I Transport My 14 Ft. Laser Sailboat on My 2016 Honda Fit?
    I have a great solution for that will work with the weight/length of your 130-pound Laser Sailboat on your 2016 Honda Fit. Unfortunately, with the approximate 125 pound maximum weight capacity of your roof, you will not be able to adhere to the roof rack weight limit since it exceeds the roof capacity. With that being said, the safest way to transport your sailboat is by trailer. I recommend the Yakima Rack and Roll Trailer - 66" # Y08106. With the Rack and Roll trailer, you will have...

  • Recommended Trailer Hitch for Towing 4 Kayaks on Small Trailer with 2015 Honda Fit
    I have two different hitches I'd recommend for towing a small kayak trailer with your 2015 Honda Fit. For a standard Class I hitch with a 1-1/4 inch receiver opening, I'd recommend the # 24920 Draw-Tite hitch you'd looked at. This is a standard hitch that would be fully visible once installed. If you go this route, you'll also need a ball mount like # 3593, along with a # 19256 for a 1-7/8 inch trailer ball or # 19258 for a 2 inch ball. If you'd prefer a hitch with the more prevalent...

  • How to Carry a Recumbent Bike and Recumbent Trike with a 2015 Honda Fit
    I hate to tell you but you will not be able to carry the bikes with your Honda Fit. The issue is that all of the trailer hitches for the Fit are Class I hitches. The types of bike racks that can hold both a trike and a recumbent bike, such as # HR1000Z-R-TRKADP, only fit Class III and up 2 inch trailer hitches. There are adapters but the use of an adapter will reduce the tongue weight capacity of the hitch by 50 percent. The tongue weight capacity of the available trailer hitches is 200...
