Tekonsha Custom Fit Vehicle Wiring - 118810

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

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.

  • 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 in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery

    • 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


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

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 rear threshold plate and felt trunk liner to access this harness.


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.

the kit was fine, the work came in trying to get under vehicle to run the 12 volt line to the rear of car, the 2020 corolla is so low too the ground, I soldered the connections then used heat shrink to cover, the rest was easy

  • Trailer Hitch Recommendation For 2020 Toyota Corolla
    I recommend Draw-Tite Sportframe Trailer Hitch Receiver part # 24983 for the 2020 Toyota Corolla Sedan. It is a Class I hitch with a 1-1/4" hitch opening so you would want to be sure your bike rack is compatible with a Class I hitch. I have attached a customer photo of the Draw-Tite with a bike rack attached. If you need wiring in the future, I recommend T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118810 which is a very reliable brand that is known to last.

  • How Much Can a 2020 Toyota Corolla Tow
    The Curt Trailer Hitch Receiver part # C34UR which is a fit for a 2020 Toyota Corolla has a 2,000 lb gross trailer weight rating which is the amount you can pull outward on the receiver with a trailer. That said, the owner's manual does trump this figure if lower or if even rated at all so you'll need to be sure to reference this ahead of time. Therefore, so long as you are under the capacity either of the hitch or vehicle then you won't have any issues. You will need the T-One Vehicle...

  • Trailer Hitch Fit for a 2020 Toyota Corolla
    We actually do have a trailer hitch for your 2020 Toyota Corolla Sedan! It is the Class I Draw-Tite Sportframe Trailer Hitch Receiver # 24983 and it has a 1-1/4" hitch receiver. You did refer to this as a tow hitch so if you planned on using this trailer hitch for towing you also need some wiring and a ball mount kit. I recommend the Tekonsha T-One # 118810 for wiring because of how reliable it is and that it bypasses your OEM wiring so you know your vehicle is protected. For a ball mount...

  • Trailer Hitch Receiver for 2020 Toyota Corolla LE
    There is one trailer hitch receiver that is a fit for your 2020 Toyota Corolla LE sedan, which is the Draw-Tite Trailer Hitch Receiver # 24983. This hitch does require drilling a small hole in the frame in order to attach it, but there is no welding required. I have added a link below to the installation instructions for you to check out. Since you mentioned towing you will also need a wiring harness and ball mount, and the exact parts you need for your 2020 Toyota Corolla are the following: -...

    Both the Draw-Tite Sportframe Trailer Hitch Receiver # 24983 and Curt Trailer Hitch Receiver # C34UR will fit all trims of the 2021 Toyota Corolla Sedan. I recommend using the Draw-Tite over the Curt receiver. The installation instructions for the Draw-Tite(linked below) show it being installed on a SE trim Corolla as well. I recommend installing the Tekonsha T-One Vehicle Wiring Harness # 118810 to give you a 4-way flat trailer lighting connection. This plug and play kit will plug into...

This Class I hitch has a 1-1/4" receiver with a gross towing weight of 2,000 lbs and tongue weight of 200 lbs. Make sure to consult your owner's manual to see what your towing capacity is before you do any towing. You will be limited by whatever capacity is lower, the vehicle or the hitch.

  • Trailer Hitch Recommendation for 2022 Toyota Carolla
    Both Draw-Tite ( # 24983) and Curt ( # C34UR) offer Class I hitches that will work on the 2022 Toyota Corolla sedan. Both hitches share the same capacity, are visually almost identical and would install in the same manner, so you could choose either without issue. I'd personally choose the Curt model, because Curt manufactures their hitches in the US. If you'll be doing some light duty towing with the hitch, you'll also need a # 118810 trailer wiring harness, a # C45221 ball...

  • Trailer Hitch and Towing Equipment Suggested for 2022 Toyota Corolla
    Per the owner's manual, Toyota doesn't recommend towing with the 2022 Corolla nor do they recommend installing a hitch. We can't recommend anything that contradicts the owner's manual, but many folks install a hitch anyway. If you decide to do so anyway and keep the weight you tow to a minimum, you could install the Curt # C34UR hitch and use a lightweight utility trailer like # K2MMT4X6. The trailer itself only weighs about 300 lbs, and I'd personally have no qualms using such a trailer...
