Tekonsha Custom Fit Vehicle Wiring - TK89FR

  • Custom Fit
  • 4 Flat
  • Trailer Hitch Wiring
  • 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.


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


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • Limited 1-year 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 threshold cover, cargo trays, and some interior paneling 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 multiplex-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.

  • Recommended Trailer Hitch Receiver, Wiring Harness & Brake Controller For 2023 VW Atlas Cross Sport
    I recommend using the Curt Trailer Hitch Receiver # C93CR on your 2023 Volkswagen Atlas Cross Sport. This receiver is made in the USA and has a lifetime warranty. The T-One Vehicle Wiring Harness # TK89FR will give you a 4-way flat connector. This connector is most commonly found on smaller trailers and also can be used with Auxiliary Lights # C53201 on larger hitch mounted accessories. If you will be pulling larger trailers which have electric brakes you will need to add a 7-Way # ETBC7...

  • Recommended Trailer Hitch for 2022 VW Atlas
    We do have trailer hitch options for a 2022 Volkswagen Atlas of which I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76176. This is a bolt-on trailer hitch option with no drilling or welding required. It has a 2" opening which is great for towing or hitch mounted accessories like bike racks and cargo carriers. If you'll be towing with the hitch then you'll also need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # TK89FR and Curt Towing Starter...

  • Curt Trailer Hitch Receiver Fit on 2023 Volkswagen Atlas
    There is indeed a Curt trailer hitch receiver that fits your 2023 Volkswagen Atlas (the regular Atlas, not the Cross Sport). I verified this directly with Curt for you, with the correct part number being the following: - Curt Trailer Hitch Receiver # C24ER

  • Recommended Trailer Hitch Fit for 2021 Volkswagen Atlas
    The # 76419 Class III hitch you referenced is a fit for the 2018-2021 Chevy Equinox and GMC Terrain, so it won't fit a VW Atlas. As long as your Atlas isn't a Cross Sport, I'd recommend the US made Curt # C24ER. Or, for the Cross Sport, use # C93CR which is also manufactured in the US. If you'll be towing with the hitch, you'll also need the # 118754 trailer wiring harness which fits all models except for the Cross Sport or # TK89FR for the Cross Sport. For a ball mount, use the # 2753...

  • Recommended Trailer Hitch Receiver For 2021 Volkswagen Atlas
    The Curt Trailer Hitch Receiver # C93CR you were looking at is confirmed to fit your 2021 Volkswagen Atlas as long as it is the Cross Sport model. To tow your trailer with a 2-5/16" coupler you will need a ball mount and a 2-5/16" hitch ball. To find the correct ball mount you will want to measure from the ground to the top inside edge of the trailer hitch receiver, and then from the ground to the bottom of the coupler on your trailer. The difference between these measurements is the drop...

  • Recommended Hitch and Wiring to Tow 3500-lbs Trailer with 2021 Volkswagen Atlas Cross Sport
    The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C93CR that fits the 2021 VW Atlas Cross Sport has a maximum towing capacity of 5000-lbs (the same as your 2021 VW Atlas), so this hitch is rated just fine to tow a 3500-lbs trailer and will do a good job. Curt hitches have a thicker powder coat than some others on the market, which helps protect the hitch from nicks that might lead to rust and corrosion on the hitch, so it's generally what I recommend using. If you DO NOT have...

  • Adding A Trailer Hitch Receiver With 7-Way Harness & Brake Controller For a 2021 VW Atlas
    As your 2021 Volkswagen Atlas has no trailer wiring, you will first need a Tekonsha T-One Vehicle Wiring Harness. I you have a Cross Sport model you will need the Tekonsha # TK89FR. For all other trim levels the Tekonsha # 118754 is the harness that you will need. These harnesses take care of the running lights, brake lights and turn signals for your trailer portion of the 7-way wiring. This connector will then plug into the Universal Installation Kit for Trailer Brake Controller # ETBC7....

  • Recommended Hitch and Wiring for 2024 Volkswagen Atlas
    For your 2024 VW Atlas I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76176. This is a Class IV hitch with a 2" receiver and a bolt-on installation. It has a max gross trailer weight of 6,000 lbs, tongue weight of 900 lbs, and comes with a limited lifetime warranty. In addition to the hitch you will also need wiring. The Tekonsha T-One Vehicle Wiring Harness # TK89FR is the most reliable option available. This plugs into the connection points in your rear cargo area. Once...

  • Mostly Hidden Trailer Hitch for 2020 Volkswagen Atlas Cross Sport
    We have mostly hidden trailer hitches like the Curt # C93CR which only has the hitch tube that hangs below the rear bumper but we do not have any Stealth brand hitches that fit the 2020 VW Atlas Cross Sport. Since there isn't a 2019 fit from Stealth either I would not anticipate one getting released either. For trailer wiring as well the Tekonsha part # TK89FR would be a great option. It's easy to install and has the most reliable converter box as well.

This hitch is made in the USA, has a bolt-on, no-drill installation and will provide you with a 2" hitch receiver. The 2" receiver is the most common size used for hitch mounted accessories such as bike racks, cargo carriers and ball mounts.

  • Hitch and Trailer Wiring Harness Recommended for 2022 Volkswagen Atlas Cross Sport
    For starters, the Curt # C93CR Class III hitch you'd looked at would work perfectly. For a trailer wiring harness, I'd recommend the Tekonsha # TK89FR trailer wiring harness. For a ball mount, use part # 40346 along with a # PC3 hitch pin. For a 1-7/8 inch ball, use # 19260 or # 63845 for a 2 inch trailer ball. I've linked to the installation instructions for the hitch and the trailer wiring harness.

  • Recommended Trailer Hitch Receiver and 4-Way Harness For a 2020 Volkswagen Atlas Cross Sport
    I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # DT96MR for your 2020 Volkswagen Atlas Cross Sport. I found that this receiver is easier to install than the Curt # C93CR that also fits your Atlas. You will not have to remove the exhaust hanger to install the receiver and torqueing the hardware is easier being as the hardware mounts through the side of the frame and not down through the frame. For the 4-Way harness I always recommend the Tekonsha T-One Vehicle Wiring Harness...

  • What is the Best Trailer Hitch for My 2021 Volkswagen Atlas Cross Sport
    The trailer hitch I would recommend for your 2021 Volkswagen Atlas Cross Sport is the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C93CR. I recommend this hitch because it has a thicker powder coat finish than other hitches, which helps protect from rust and corrosion. For a wiring harness I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK89FR, because of the reliability the Tekonsha harnesses have.

  • Compatible Trailer Hitch Receiver For A 2022 Volkswagen Cross Sport
    Yes, the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C93CR is the correct fit for your 2022 Volkswagen Cross Sport. This fully welded trailer hitch receiver bolts onto your Volkswagen Atlas Cross Sport's frame with no welding required. This bumper is designed to sit very close to bottom of the fascia so trimming of the fascia may be needed to provide proper clearance for the receiver tube. If you plan on towing a trailer you'll also need a trailer wiring harness. For this...
