Tekonsha Custom Fit Vehicle Wiring - 118753

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

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.


Features:

  • 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 point in rear cargo area
    • 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


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the passenger's-side interior trim panel in your rear cargo area. 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 flat connector will be stowed in your rear cargo area.


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.

Product installed per video, needed a floor jack and prop van up on some wood blocks to install. All went well, happy with purchase. 809957

I love it!!! I was looking for a stock look and you guys NAILED IT! all that is visible is the receiver. everything else is neatly hidden under the bumper skin which cut nicely with my multi tool. For my wiring harness I tied into the fuse panel by the vacuum instead of running a wire to the battery. I did still use the supplied fuse, i just plugged into one of the unused constant power plugs. If I had to be picky I would request a better photo of the rear bumper or even better a template for cutting. that was the only part that had me sweating. Lift gate sensors are not blocked and still work perfect with no mods needed. 803737

Ask the Experts about this Tekonsha Custom Fit Vehicle Wiring

  • Difference Between Tekonsha Trailer Wiring Harnesses that Fit 2019 Honda Odyssey
    The big difference between the two Tekonsha trailer wiring harnesses that fit your 2019 Honda Odyssey is how they draw power to activate the trailer lights. The # 118753 has a wire that runs up to the vehicle battery which is used to power all of the trailer lights directly from the battery. This is a much safer setup but the install in more involved and it costs more. The part # 118781 installs much easier but it draws power for the trailer taillights through the wiring panel of the Odyssey....

  • Recommended Trailer Wiring and Brake Controller for 2020 Honda Odyssey
    I'm not sure how you went about wiring your old van but with the new 2020 Honda Odyssey the easiest way to install a 7-way trailer connector is by first adding a 4-way and then converting it to the 7-way. For the 4-way I prefer the Tekonsha options because I like the converter box to be secured with a screw instead of double sided tape like the other option. One of two different Tekonsha harnesses work for your van; use part # 118753 if your van has no pins in the 10, 11, and 12 cavities...

  • Recommended Wiring Harness For 2018 Honda Odyssey
    The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118753 is currently the only confirmed fit we have from any manufacturer. The power wire to the Modulite is a little inconvenient to run and I get that it is easier to get a harness that doesn't use it, however, it is a safer harness. Because it draws its power from the vehicle battery, it protects the factory wiring from overdraw preventing an overload to your electrical system. I've attached an article on routing...

  • Brake Controller Recommendation for 2018 Honda Odyssey
    You will need to start with a 4-way for your 2018 Honda Odyssey (if you do not have one). For that you would want the # 118753. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885....

  • Do Additional Fuses get Installed for a Trailer Wiring Harness for a 2018 Honda Odyssey
    The only fuse that gets installed for trailer wiring harness # 118753 for the 2018 Honda Odyssey is the one included with the kit for the power wire. The only thing getting plugged in on the right (passenger's side) is the set of connectors for the harness. I have linked the manufacturers instructions for reference.

  • Recommended Trailer Brake Controller and Wiring Harness for 2020 Honda Odyssey
    The brake controller I highly recommend for your 2020 Honda Odyssey is the Curt Echo Mobile Trailer Brake Controller # C51180 because it is the easiest brake controller on the market to use and install. The reason the Echo is so simple is because it is controlled with an app on your smartphone, a device that you're already comfortable using so there is not going to be any unfamiliar hardware or poorly-written manual to keep poring over simply to use your controller. The Curt Echo will...

    I can see why this might be confusing and there are some differences between all 3 of these wiring harnesses. I'll start off by explaining the differences between the Tekonsha # 118781 and # 118753 wiring harnesses. The main difference is that the # 118753 is designed for vehicles that do not have the towing fuses already in place. In order to determine which one you can use on your 2020 Honda Odyssey you'll need to check the rear interior fuse box, which is located on the left side...

The T-One Vehicle Wiring Harness part # 118781 is what I recommend because when compared to the T-One Vehicle Wiring Harness part # 118753 comes with additional fuses that may or may not be needed to activate the tow package.

    Both the Draw-Tite Max-Frame Trailer Hitch Receiver # 76171 and the Curt Trailer Hitch # C13370 referenced in your question are Class III hitches that are confirmed to fit your 2018 Honda Odyssey. These will both install at the same location on your vehicle's frame and the hitch visibility for both models will be about the same. The primary difference between the two is their weight capacity. The Draw-Tite # 76171 features a higher 4,500 pound towing capacity and 675 pound tongue weight...

  • Difference between Item # C56382 and Item # 118753 for a 2018 Honda Odyssey
    The difference between the Curt # C56382 and the Tekonsha T-One # 118753 for your 2018 Honda Odyssey is that the Curt is for if the fuse locations actually have pins in them. The Tekonsha option is for if the fuse locations are lacking the pins to activate the tow wiring. The Tekonsha basically bypasses everything and pulls power straight from the battery via the black wire (which runs to your battery) while the Curt utilizes factory wiring on your vehicle.

  • Hidden Trailer Hitch and Trailer Wiring Recommendation for 2019 Honda Odyssey
    The hitch and wiring kits for a 2019 Honda Odyssey are the same as the 2018 models. The etrailer.com hitch part # E95588 is a fit for either. The other hitch I would recommend though is the Draw Tite part # 76170 as only the hitch opening will hang below the rear bumper which makes it the least visible. For wiring the best option is the T-One kit part # 118753 which is a custom fit and the brand we offer that has the most reliable converter boxes. If you wanted to do some towing...

  • What Trailer Hitch for a 2019 Honda Odyssey EX Has The Most Concealed Look
    Correct, the actual cross tube portion of the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76171 is recessed more so than the Curt Trailer Hitch Receiver part # C13370 or the etrailer.com Trailer Hitch Receiver part # E98855. The Draw-Tite hitch however does become less recessed as you get closer to the receiver tube opening. To give you a better idea of this, the distance from the center of the hitch pin hole to the outer edge of the bumper is 4" with the Draw-Tite hitch and 3" with...

  • Recommended Trailer Hitch for 2018 Honda Odyssey
    There are hitches available for a 2018 Honda Odyssey, and I recommend going with the Draw-Tite # 76171. This is a Class III hitch with a 2" receiver that has a tongue weight capacity of 675 lbs and a gross towing weight capacity of 4,500 lbs. You will still be able to use your Odyssey's tailgate foot sensor; just activate it on either side of the receiver tube. If you plan on towing, you can use ball mount kit # 989900 and for wiring you would need T-One Vehicle Wiring Harness # 118753....

  • 2020 Honda Odyssey Difference Between Tekonsha 118781 and 118753 Wiring Harnesses
    Both the # 118781 and the # 118753 are indeed confirmed to fit the 2018-2020 Honda Odyssey, both use T-connectors to plug into your tail light connectors, and both are rated at 5 amps for the stop/turn circuit and 7.5 amps for the tail light circuit. The main difference is that the # 118753 includes extra wire to run a power wire to the battery, whereas # 118781 comes with extra fuses which activate the "tow package" and power the harness through it. So, which one do you need? Well,...

  • What Is the Best Trailer Wiring Harness Option for 2020 Honda Odyssey
    As long as your 2020 Honda Odyssey doesn't fall into the extremely rare category of Odysseys that are missing terminals on fuse locations #10, #11 and #12 inside the fuse box, your best option is to go with the Tekonsha # 118781. Curt offers a similar option with the # C56382, but in our experience, the Tekonsha harnesses, and their converter boxes in particular, seem to do a better job and have proven to outlast the competition. If you want to be extra sure, you can look behind the...

  • Differences Between Available Class III Hitch Options for 2020 Honda Odyssey
    Both hitches would share the same 525 lb tongue weight/3500 lb towing GTW towing capacity, but the similarities would end there. The Draw-Tite # 76170 is a concealed design, meaning that the majority of the hitch would be concealed behind the Odyssey's bumper when the hitch is installed with just the receiver and safety chain loops being visible. Because of the concealed design, the bumper cover would need removal to install the hitch and would be reinstalled afterward. The Curt # C13370...

  • Will Curt Trailer Hitch C13370 Block Hand's Free Lift Gate on a 2018 Honda Odyssey
    With Curt trailer hitch # C13370 installed on your 2018 Honda Odyssey the Hands-free Liftgate sensor areas may be limited to areas away from the center where hitch receiver opening is located but not completely block them. If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip,...

    You're going to need a custom trailer hitch receiver and a custom wiring harness for starters. On your 2019 Honda Odyssey I recommend the etrailer.com hitch, part # 76170. I like how the receiver tube is all you see under the van's bumper and the cross tube is completely hidden. The wiring harness that fits is part # 118753. It's a 4-way connector and plugs right into the van's wiring behind a trim panel in the rear cargo area on the passenger side. I've linked the install details...

This is a Class III hitch with a 2" receiver that is a complete bolt-on installation so no drilling into your 2018 Honda Odyssey's frame is required. For wiring which will give you a 4-way connector and allow you to power your trailer's lights you need Wiring Harness # 118753.

I attached an install video for this kit for you to check out on a similar 2018 model as well.
