Tekonsha Custom Fit Vehicle Wiring - TK69FR

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat

  • 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
  • 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 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.

Easy install, all plugs matched my OEM connectors



by:
2021 Toyota Sienna

Relative easy install plug in, route wire, secure ground. Pretty straight forward. Now I need a trailer to hook it to. Prepping for a move with a U-Haul trailer. However my flat 4 pin trailer wiring test plug indicates it should be correct.



by:
Toyota

This product was simple amazing! I was shocked at how easily it installed - actually plugged into a pigtail hidden in the sidewall of my Toyota Sienna! I would rate this device as a 10 if that were possible! Toyota doesn't want you to know about this product because they don't want you pulling anything with a hybrid! Toyota actually started offering it - then quickly discontinued it! So glad this product was available!



by:
2021 Toyota Sienna

Extremely easy to install on 2021 Sienna. Just plugs right into existing socket and then ground to existing bolt under the spare tire.


Comments
After a year, this adapter continues to work perfectly.

Husband was happy with receiver and wire harness. Had all installed in around an hour.



by:
Toyota Sienna

Hitch receiver fit perfectly on the 2021 Sienna. It was easy to install and does the job nicely.



by:
2021 Toyota Sienna

Great website, better than most others out there since it includes detailed information including videos as to how to install the equipment and trailer light system.. Quick delivery, great communication throughout the process. Would definitely recommend etrailer to anyone and everyone I know.



by:

This wiring harness was SIMPLE to install. No splicing or cutting. Plugs effortlessly into
my Sienna’s harness.
Most importantly the e trailer folks care about their customer.



by:

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



by:

Great quality but I got my order 4 days late



by:
2021 Toyota Sienna

Exact fit for factory trailer harness. No cutting or splicing. Instructions are incorrect; the harness is next to the spare tire, and grounding screws are already in place. No need to remove any panels or drill any holes. Kit could use a 6mm nut for the existing grounding screw. 10 minute installation.



by:
2021 Toyota Sienna

Ordered this with a trailer and both were delivered as promised. I found the information on installation excellent even to small details for my vehicle.



by:

Installation was a breeze. No wire splicing. Plugged into my 2021 and it's been working great!



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.

2010 BMW M6

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.



by:

This was so easy to install I thought I was doing it wrong.
Everything worked perfectly.
Thanks



by:
2022 Toyota Sienna

Like all the other reviews, installation was a breeze.



by:
Toyota Sienna

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!



by:

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



by:
2021 Toyota Sienna

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.



by:

Easiest wiring harness ever! No cutting, splicing or removing tail light on a 2021 Sienna!



by:
Toyota Sienna

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.



by:

Product as described. good price. delivery a little slow but arrived at time stated



by:

Plugged right into the factory connector and works great!



by:
2021 Toyota Sienna

Very poor directions not accurate.


Comments
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.

  • Installation Time To Install the Tekonsha Vehicle Wiring Harness # TK69FR on 2021 Toyota Sienna
    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...

  • Where Does the 4 Pin Connector Attach to My 2021 Toyota Seinna?
    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. It is a plug in adapter that requires no cutting or splicing. It can be stored in this area until you need to use it then you would just have it hang out the rear door so it can connect to your trailer.

  • 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.

  • Trailer Wiring Recommendation for a 2022 Toyota Sienna
    I have the perfect solution for you with the Tekonsha T-One # TK69FR! This connects to the OEM plug on your 2022 Toyota Sienna and gives you the basic trailer lighting functions that you'll need to tow a small trailer. If you don't already have a ball mount/hitch ball kit then I recommend checking out the etrailer Ball Mount Kit # 989891 which comes with a ball mount and a few hitch ball options to fit your towing needs. Attached are some review videos for you to check out.

  • Do I Need a Weight Distribution Hitch for a 3500 lbs Trailer and a 2017 Toyota Sienna?
    Thanks for the pictures! It sounds like you would benefit from having a weight distribution system and all of your components are compatible with one. 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...

  • How To Hook Up Two Pin Brake Plug on Jayco Trailer
    I do have an option for you but the only way for you to tow this trailer and have everything work would be to switch from the odd two plug setup to a standard one plug, 7-way trailer connector. This can be done easily with a junction box like the etrailer Trailer Wiring 7-Way Upgrade Kit part # e99011. I am not familiar with the plug you have shown but I'm fairly confident there is no adapter for this.

  • Choosing 4-Pole Trailer Wiring Harness for 2021 Toyota Sienna
    For your 2021 Toyota Sienna, I'd highly recommend going with a plug-and-play option, such as the Tekonsha # TK69FR which would work perfectly with no cutting or splicing necessary. As far as a mounting bracket, you really won't need one as the manufacturer recommends leaving the 4 pole connector in the cargo area of the vehicle when it's not being used. This protects it from damage and from the elements. When you need the connector, you can simply run it out the rear hatch (keeping it...

  • Will Curt Trailer Hitch Receiver C22UR Disable Hands Free Lift Gate Sensor On 2021 Toyota Sienna?
    While Toyota is somewhat correct that installing the Curt Trailer Hitch Receiver # C22UR on your 2021 Toyota Sienna will partially block the hands free lift gate sensor, it will not disable it. 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. If you are planning on towing with your Sienna you will also need a vehicle wiring harness # TK69FR. I included a link to the written instructions of...

  • How To Hook Up Reverse Light Circuit On 2021 Toyota Sienna To 7-way Connector ETBC7L
    I would be happy to help! The 4-way connector # TK69FR you purchased for your 2021 Toyota Sienna cannot have a reverse light circuit, as it does not have enough circuits in the connector for a 5th function. Instead the # ETBC7L 7-way connector you purchased is what will have the reverse light circuit. You will just need to hook up the yellow wire on the back of the 7-way to your reverse light circuit. Using the circuit tester included with the # ETBC7L will help you find the correct reverse...

    For your 2022 Toyota Sienna, there is one option for a brake controller that stands above the rest, from Tekonsha: - Tekonsha Prodigy P3 Trailer Brake Controller # 90195 I really like the P3 because it will give your trailer the most consistently smooth braking, it has a bright LCD screen that is very easy to read, and it has continual diagnostic checks with safeguards to prevent battery drain or shorts.
