Installation of Tekonsha Brake Controller Adapter

For most applications, the factory plug is located beneath the dash, near the center console. If you have a Ford full-size van, the harness is underneath and to the left of the steering column. The Ford Explorer and Mercury Mountaineer have 6-pin connectors behind the glove box on the passenger's side. On a Ford 2010 Flex, the connection point is under the front edge of the dash directly below the steering column. On a 2013 Ford Explorer, the connection point could be behind the driver's side kick panel. On a 2014 Ford Explorer, the brake controller port is located by the steering column.

To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.

This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2021 Ford Explorer

Exactly what I needed to install my Tekonsha Primus IQ brake controller in my 2021 Ford Explorer. The install video from eTrailer was perfect and made the install really easy!!



No issues a year later. Wiring adapter still doing its job!


Worked out perfectly for me, super easy installation with adapter harness. Work's flawlessly, easy one hand gain control with control's on front. My truck had nice cubby it fit in so out of the way and seamless look. Thanks for a great product and service.



Working great, easy install


Easy plug and play installation on my 2007 Mountaineer. So much better than having to wire the whole thing myself.

Wayne S.


Still working just fine. The Tekonsha controller and adapter performed fine on a long tow from NJ to OK and back last year, and I suspect they will continue to work just fine in the future. Definitely the way to go if the factory wiring is present.


Works like a charm. So easy to install I think anyone could do it. I’m totally satisfied. We’ve used our travel trailer about 6 times during our first year.The brake controller is flawless.

2010 Land Rover Range Rover

I ordered the trailer brake adapter harness for my 2010 full size Range Rover.
It fit great and its well made to do the swap,
for others that will read this here is how.
I found the brake connector in the truck was hidden behind the fat harness thats next to the inside left kick panel, just behind the hood release panel
By pulling on the OBD 2 wire harness, I found it was tied to the OBD harness.

Some say that the connector is on the left side of the steering column , in my truck is was on the far side of the fat harness so it was hard to see.

I had to remove the left side console, I removed the screw, then pulled the bottom of the wood panel towards the left door, the 2 pins released, then the panel slides to the rear of the truck to dislodge the top pin.

5 screws secured the lower panel , remove the lamp ,unplug it,
then remove the OBD 2 connector from its mount , slide the gray collar to the left kick panel then the harness pushes up out of its holder.
Plug in your new adapter harness for your trailer brake controller,
Assemble is the reverse of taking it apart.
in the picture the new harness is connected to the gray connector

This harness works as it should, a good product,


I ordered a Draw-Tite 5535 Brake Controller & adapter cable 3035-P from etrailer for my 2011 Ford Holiday Rambler F53 Chassis RV to tow my Tow Dolly with electric brakes. I ordered the parts on Saturday and received them on Thursday using economy shipping rate which was great. I received just what I ordered and installed them today (Friday) everything worked perfect and the install was very quick and easy.

Great no problems, Plug & Play made a hard job easy.

Isuzu Rodeo

Multiple products which I purchased from Etrailer to upgrade my Capri Rodeo truck camper. The steps are well made, easy to setup, and extremely helpful in entering and exiting. I set them next to the door when travelling. The trailer brake controller smoothed out the jerking that was a problem for far too long and simple to install. The vent cover was definitely needed as the original had a hole in it. The removal and replacement went well.

All the items are quality products and still working well.

2007 Ford F-150

I haven't towed with the it yet. But installation on my 2007 Ford F150 was pretty simple. The plastic panel I attached it to had steel behind it. So I removed the plastic panel, mounted the bracket, then trimmed the excess length off the screws, and reinstalled the panel. The wiring harness plugged right into the truck's plug under the steering wheel. It seems like a great product, and having the specifc wiring harness for my truck made it simple to install. Sheila was very helpful too. Thanks.



Ive been using it now for a year. It works great!

2015 Lincoln Navigator

I'd ordered the Tekonsha Prodigy P2 Proportional Trailer Brake Controller (1 to 4 Axles ) on a Monday with a Wednesday delivery date of two days, as I'd specified. I have a Lincoln Navigator that had the factory installed heavy tow package. I had also ordered the adapter connector for Prodigy P2 controller to the Navigator's factory plugin. The entire install took me 15 minutes. I found the video review of the controller quite helpful as it demonstrated how to static set the controller's setting before drive trials and how to set the "boost" settings. Good price and very easy to install.

Michael M.


The device is still working as advertised!


It was an easy installation, plug and p lay


Fit and works great on my 2001 F-150 with a Tekonsha P3 Electronic Brake Controller



Still going STRONG a year later...!!


The wiring adapter connected properly to my truck's factory, wiring adapter for electric trailer brake controller. It also subsequently connected properly to the Tekonsha Brake EVN electric brake controller I also purchased from etrailer. Everything worked properly towing my trailer.


Customer service is great ! Jamie is the best Alex is second best??
I would try not to use usps as there services are not fast enough.
Thank you for all of your help getting the correct brake actuator for
Disc brakes!

2015 Ford F-150

This is the first trailer brake controller I have ever purchased or used so I don't have any past experience for a reference. However I think I hit the jackpot with this. The installation was easy and took me no longer than 15 minutes after a quick review of the installation instructions. I have a 2004 F150 and along with the Tekonsha Brake Controller I purchased the Wiring Adapter which made the installation very easy. Took it for a test run and it works awesome. Good product.

Ford F-150

I bought the Prodigy 3 controller and the plug and play harness for my f150 and installation was a breeze. The main trailer I use has four wheel brakes and I sometimes haul very heavy loads. The controller has worked flawlessly! Thanks for a great product and thank you Angela for awesome customer service!


Excellent quality and delivery was quick. Fits the application perfectly and functions as expected.


Awesome controller. Works well with both of my trailers. Super easy to adjust brakes . Looking to get another for the wife’s suv.


Ordered a trailer brake controller and the wire harness adapter for our Motorhome. Everything fit and works perfectly. Very easily installed.


Plug and play high quality construction here it is 2023 purchase this product for a 2004 truck that I purchased. It was a simple as they told me.


This company has been amazing to work with. Fast when it comes to shipping very helpful. This time I had Roger R. as my salesperson extension number 79340. Answered lots of questions help me find what I was looking for look forward to getting everything installed and up and running. Great company very big on the service part. Thank you


Parts arrived early installing was a snap and the video was helpful in finding the plug under the dash
System set up seems straight forward and i will be hitting the road to test soon e trailer supplied everything where my local auto parts had the controller but couldn't get the cable..highly recommend the factory ford pigtail


With Ford adapter was plug and play. Have not used it yet, but will be within a week or so.

2006 Ford F-150

worked perfectly and good quality . Should get torn or ripped and don't have to worry about electrical tape



perfect. The wiring does have to be strongly zip tied to not move over time . I had to redo mine about 5 months ago . That's user error install tho .


Plug and play. Very simple. Worth every penny.


My 1994 f250 was wired different so I couldn’t use the adapter. I used the universal plug that cam with the break controller
