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.

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

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.

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

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


When I needed to get a brake controller for our RV, I was told that I needed the cable, and it was included. Upon receipt, the cable was not included, and was told again that I needed it and I had to order it separately. While working with your tech to resolve wiring the brake controller, he determined I could not use the cable and to splice wiring as he told me. Requested return of cable, was lead to believep shipping would be free. But, I had to pay about $xx.xx to return the item and only got a fraction of what I paid as a credit. AND the brake controller still doesn't work as the product instructions indicate it should. I will never order again from your company or suggest anyone order from you.


This Adapter Makes It Easy! I'm not a mechanical guy and I REALLY hate messing with electrical systems. I wanted to install the Tekonsha P-3 on my motorhome but I did NOT want to cut wires, take apart dashboards, etc. The good news is that, after doing some reading on the etrailer website, it appeared that my MH probably had a pre-installed wiring harness for the trailer brakes and all I needed was this adapter. Took me all of 5 minutes to find the connector (4 of which were spent squeezing my plus-sized body in front of the drivers seat), 15 seconds to plug in the adapter and another 15 minutes to mount the P-3 (the majority of which was taken up trying to decide on the best location.) Worked great on the first try! I would highly recommend this product and the service / help at


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.

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,

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.

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.

The device is still working as advertised!

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!

2003 Ford F-350 Super Duty

Nice and clean a pain to plug into my 03 because the factory plug is mounted in a nest and wouldnt move so we had to get creative to plug it in other than that great


Have not had an opportunity to use the item. The plug-in wiring adapter would not plug into the 2021 F53 chassis trailer wiring harness. Ford changed the plug and it is still not available for purchase. The plug- in harness must be hard wired to the chassis trailer wiring harness. Will let you know when I get it Hooke up


Instructions were great, every thing fit, and the controller works great and is adjustable according to your load. I wish everybody's stuff that I purchase would work as good as your products. You even had some instructional videos to pre-train me prior to purchasing and starting the install. Service is king.

Excellent, zero problems. Works great.

The plug-in wiring adapter fit perfectly with the Ford wiring harness, making for an easy install.


I ordered an adapter for this brake controller with the help of customer service rep and the part didn’t fit. Called back and the rep I talked to couldn’t figure it out so she said a tech would call me the next day. No call by 2PM SO I called and the 3rd tech said that the chassis my motor home was built on was a year earlier and they changed the wiring. Ordered that adapter and wanted it soon for a trip so had it overnighted. We’ll see if it fits today when it comes. etrailer has been very good in the past but they fumbled on this one.

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!


Vicki and Etrailer are a joy to deal with. She found the product that I needed and went above and beyond to get the connector to me promptly. I do not even look anywhere beyond Etrailer for all my electrical and trailer related products.
Hats off to Vicki and Etrailer


There was a lot of searches. But I eventually found the information that applied to my application. After that, everything fell into place. All the product links were right at my fingertips and the solution became easy. The prices were good so I could afford to get some extra things to make the project fun. The order tracking and delivery were top notch. I will shop Etrailer again.


I have ordered several items from e-trailer and they have always shipped ontime and the price has always been great!


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

2003 Ford F-250 Super Duty

Was exactly the right harness fir my 2003 F250. Installation was a breeze!


Took me less than 10 min to install, works great, very good price. Will but from here again, came in a timely manner

2022 Ford Explorer

Purchased for connecting Draw-tite I to 2022 Explorer and connected right up to wiring harness under dash, as advertised. No big deal other than standing on my head to find the connector tucked under dash, but this was way easier than trying to wire into the connector. Plugged right in and worked


Installed the brake controller today harness worked as it should.
