Tekonsha Custom Fit Vehicle Wiring

  • 4 Flat
  • Trailer Hitch Wiring
  • Tekonsha
  • 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 - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily

    • Plug in T-connector
    • Connect 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 in your rear cargo area. You will have to remove the rear threshold plate and some interior lining to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way 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.

  • Trailer Hitch Receiver and Wiring Harness For a 2022 Hyundai Elantra SEL
    The Draw-Tite Sportframe Trailer Hitch Receiver # DT75MR will fit your 2022 Hyundai Elantra SEL. This receiver will fit all trim levels of your Elantra except the N-Line and Hybrid trims. The Receiver # 24939 that you were looking at will only fit the 2017-2020 model years. I recommend installing the T-One Vehicle Wiring Harness # TK86FR when you install the receiver. The 4-way harness will allow you to connect to small trailers as well as Auxiliary Lights # C53201. Auxiliary lights are...

  • Recommended Hitch for a 2023 Hyundai Elantra
    Yes, we do. For your 2023 Hyundai Elantra sedan, I recommend the Curt Trailer Hitch item # C53NR. This hitch is confirmed to fit all models of the 2023 Elantra except for the N and N-Line trims. The Curt Trailer Hitch item # C53NR is custom fit and bolts to your Hyundai with included hardware. It is a class I hitch with a 1-1/4" receiver. It has a 2,000 lbs maximum towing capacity and a 200 lbs maximum tongue weight. If you are planning on towing you will also need a wiring harness item...

  • Recommended Hitch for a 2023 Hyundai Elantra
    The Curt Trailer Hitch item # C53NR requires both drilling and cutting to install on your 2023 Hyundai Elantra. I have taken some screenshots from the instructions and attached them below to show you these steps. I have also attached a picture that shows the Curt Hitch installed. At this time 5/17/2023 there are no other options for hitches for the 2023 Elantra. The Curt Trailer Hitch item # C53NR is custom fit and bolts to your Hyundai with included hardware.

  • Will The Curt Trailer Hitch Receiver C53NR Fit a 2023 Hyundai Elantra Hybrid?
    The Curt Trailer Hitch Receiver # C53NR shows it will fit every trim of the 2023 Hyundai Elantra besides the N and N-Line trims. I cannot find any information saying it will not fit the hybrid and the N and N-Line trims are not available with the hybrid engine configurations. The T-One Vehicle Wiring Harness # TK86FR will provide you with a 4-way flat. This connector will control the lights on most small trailers you may tow and will also allow you to use Auxiliary Lights # C53201. The...

  • Trailer Hitch Fitment for a 2023 Hyundai Elantra N (Not N Line)
    The only exceptions to the fitment of the Draw-Tite Sportframe Trailer Hitch Receiver # DT75MR on a 2023 Hyundai Elantra are the N Line and Hybrid models. Since your N model is neither one of these you'll be good to go! Keep in mind that this is a Class I hitch with a 1-1/4" receiver so you will be limited to carrying 2 bikes with it and a total tongue/towing weight of 200 lbs/2,000 lbs respectively. To tow a trailer you need the T-One Wiring # TK86FR and a ball mount kit like part # C45147....

  • Height Of The Draw-Tite Sportframe Trailer Hitch Receiver DT75MR For Ground Clearance
    Since we have not installed the Draw-Tite Sportframe Trailer Hitch Receiver # DT75MR on a vehicle in our shop the only measurement that I can give you is the height of the receiver from the frame. The receiver is 7" tall from the frame mounts to the bottom of the receiver tube. You will need to measure from your frame rail down to determine where this is on your 2021 Hyundai Elantra. The T-One Vehicle Wiring Harness # TK86FR will give you a 4-way flat connector that can be used for small...
