Tekonsha Custom Fit Vehicle Wiring - TK69FR

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • No 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 in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery

  • 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 the rear cargo area. You will have to remove the plastic threshold cover, side panels, cargo trays, and interior trim panels 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 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.

Great product took me about 10 minutes to install. Would be nice if it came with a M6 nut so you could just screw it onto the connector that is already in the car. It would also be nice if it came with a grommet already on the wire and a way to mount it to the hitch. I cut the existing grommet and zip tied the wire to the hitch so I don't have to drag it through the back door everytime I want to use it.

The 2021 Sienna has the connector underneath the spare tire, two mounted screws perfect for the grounding wire, and a rubber cover for easy access to underneath the vehicle to route your 4-way. The trailer hitch receiver was easy to install, but the instructions were also wrong (removing the cover underneath the car was on the driver side, and not the passenger side). 5 stars as long as they get the instructions fixed so people don’t unnecessarily tear apart their car!

It had a few chips on the paint, other than it fit well and the wiring kit plugged right in to the Orem wiring harness

The trailer wiring harness was a perfect fit for my 2021 Toyota Sienna. with the optional spare tire I did not have to remove any trim clips.

2021 Toyota Sienna

Thos wiring kit works great and fits perfectly under the spare tire where the connector is located. The tekonsha kits Instructions say to pull panels and look under carpet by rear seat in hatch area. Wrong. That's too much work and you'll get no where but once you figure it out it's perfect and easy to install.

Works well, but a little tricky to install. Would have appreciated better instructions (with more details on how to remove panels) to make the install easier on my 2021 Sienna.



- TK69FR
by:

It worked for a few months, then all the trailer lights stopped working.


Comments
First, I would check for corrosion and apply grease to electrical connections. Next, I would check the ground ring terminal to make sure there is no debris near it making it hinder the connection. Customer Service will contact you regarding the 1 year warranty.

Excellent. Five stars. Very easy to install, took me about half an hour. Only minor complaint is that there were a few small spots on the hitch that were not powder coated, so I’ll touch those up with enamel. I was also able to trim the underside panel a little more conservatively so as to leave the aft bolt attachement in place. Maybe not a big deal but given that it’s plastic and supposed to protect wiring from salt and road grime, I figured leaving as much intact as possible would be a good thing. etrailer shopping and follow up were great

I am sorry to hear this. Usually, we have a video installation guide but because this is a newer model, we have not had anyone bring this in yet for us to test fit and record.

  • Draw-Tite or Curt Trailer Hitch For 2021 Toyota Sienna
    Let's start with the two trailer hitches you were referring to that fit your 2021 Toyota Sienna, which are the following: - Curt Trailer Hitch Receiver # C22UR - Draw-Tite Max-Frame Trailer Hitch Receiver # DT55MR They are very similar 2 inch hitches that are both easy bolt-on installations, but I recommend the Draw-Tite # DT55MR, for a couple of reasons. One is that it has higher overall capacities, which not only speaks to the strength of the hitch, but the higher tongue...

  • Does Trailer Hitch For 2021 Toyota Sienna Have Difference in Ground Clearance
    There won't be a difference regarding ground clearance for either of the hitches that fit your 2021 Toyota Sienna, the Curt Trailer Hitch Receiver # C22UR or Draw-Tite Max-Frame Trailer Hitch Receiver # DT55MR. This is essentially the same hitch in many ways, though I do like the Draw-Tite # DT55MR over the Curt because of its higher capacities as well as its finish, which isn't as glossy and gives a more refined look. That said, both hitches have visible crosstubes are and going to...

There is no plug in play 7-way for your vehicle, you have to first install the 4-way and adapt it in order to make it a 7-way.

With the 4-way connector installed there are two options for a 7-way connector.

  • Where Does Tekonsha Trailer Wiring Install on 2021 Toyota Sienna
    The Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # TK69FR attaches in the rear cargo area behind the panel the jack is stored in. Basically you'll just have to take apart the rear cargo area of the van until you get to the area behind the jack and from there you'll find the port. I wish we had an install video I could provide but at this time (November 2021) we have not had chance to install this kit.

  • Recommended 7-way/4-way Connector and Trailer Brake Controller For 2022 Toyota Sienna
    We have exactly what you are looking for! The 7-way connector I recommend for your 2022 Toyota Sienna is the # ETBC7L which is designed for wireless brake controllers such as the Curt Echo Wireless # C51180. I prefer this option as it will not require you to mount a trailer brake controller inside of your Sienna, and you will not need to drill any holes or run any wires in the interior. It also has both a 7-way and 4-way connector just like you were wanting. To install the # ETBC7L...

    Tekonsha gives a installation time of 30 minutes for the T-One Vehicle Wiring Harness # TK69FR on your 2021 Toyota Sienna. This is typically a time given for an experienced technician who has experience with the vehicle and its components. As we have not had a 2021 Sienna in our shop to install this part on ourselves currently we have not included our rating on this product yet. I would think that this would be a roughly 1 hour installation depending on your mechanical ability and knowledge...

I recommend the Blue Ox SwayPro Weight Distribution item # BXW0556. This is a clamp on system that requires no drilling into your trailer's frame to attach the hanger brackets. The built in sway control will keep your trailer in line with your 2017 Toyota Sienna when you're driving down the highway and get passed by a semi. It has a 6,000...

    The Draw-Tite Trailer Hitch Receiver # DT55MR you were looking at for your 2021 Toyota Sienna does not have a concealed crosstube as you can see from the included installation photo. Both the trailer hitch receivers available for your Sienna, the # DT55MR and # C22UR, are exposed hitches meaning the receiver and crosstube is visible so I recommend going with the # DT55MR due to it having the higher tongue weight rating of 675lbs and a higher trailer weight rating of 4500lbs.

You will just need to place your foot on either side of the receiver and move your foot in and out until you find the sweet spot for the sensor.
