Tekonsha Custom Fit Vehicle Wiring - TK33VR

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


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 points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite power module that 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 tail lights on both the driver's side and passenger's side. You will need to remove the protective covers 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 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 Power Module

A ModuLite power module is built into this T-One connector. 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.

  • Troubleshooting T-One Wiring Harness Installation on a 2022 Ford Bronco
    Thank you for your purchase of the T-One Vehicle Wiring Harness # TK99VR for your 2022 Ford Bronco! To start off troubleshooting we'll want to make sure you have the correct harness. The part # TK99VR you have is if your Bronco has LED taillights. If you don't have the LED taillights then you need the T-One # TK33VR instead. It looks like the non-LED setup has the brake function tied in with the turn functions but if you have the LED setup then the brake function has it's own circuit....

  • Why Does Trailer Wiring for 2022 Ford Bronco Require Running Wire up to Vehicle Battery
    Modern trailer wiring kits like the part # TK33VR which fits your 2022 Ford Bronco if it does not have LED taillights or the part # TK99VR if you do have them do require running a power wire up to the battery to draw power from for the trailer's taillights. This is due to vehicles now having a much more delicate wiring system and also because they've found that these kits prevent issues on the tow vehicle and trailer wiring. In the event of a short the Bronco's wiring isn't going to end...

  • Best Trailer Hitch Receiver & Wiring For 2022 Ford Bronco
    Let's start with the trailer hitch for your 2022 Ford Bronco, and there are a couple of options, the Curt # C76WR and Draw-Tite # DT37GR. Between these two, I highly recommend the latter: - Draw-Tite Max-Frame Trailer Hitch Receiver # DT37GR The Draw-Tite really outclasses the Curt in every way; it is stronger, with higher capacities of 4,500 lb towing/675 lb tongue weight compared to the Curt's 3,500 lb towing/350 lb tongue weight, and has much better clearance, as you can see in the...

  • Comparing Curt and Draw-Tite Trailer Hitch Receivers For a 2021 Ford Bronco
    I as well am not an engineer but I can tell you that Draw-Tite has built and tested the Max-Frame Trailer Hitch Receiver # DT37GR strong enough to be able to handle 675lbs of tongue weight and a trailer weight of 4,500lbs. You do want to take into consideration that while the receiver is rated for these numbers you will still not want to exceed the specifications on your 2021 Ford Bronco. If you can't find these in your owners manual the service department at your dealer should be able...

  • Parts Needed to Flat Tow 2022 Ford Bronco
    Curt Manufacturing shows the Custom Base Plate Kit, # C59JR to fit the 2021 Ford Bronco but they do not list it as a fit for the 2022 model year. In addition, this base plate option is limited to only being used with the Curt Rambler Steel Tow Bar for Curt and Blue Ox Base Plates, # C26FR. While this is a decent tow bar option, we have several options that are better and can be used with a wider selection of base plates. My recommendation for your 2022 Ford Bronco with Ford Performance...
