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.

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.

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!

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.

2005 Ford F-150

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!

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 .


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

  • Installing Brake Controller Wiring Adapter Part # 3035P on 2004 Ford Expedition
    The connection point for the brake controller should be located under the dash just above where where your right leg would be if you were behind the wheel. I have an installation video that shows the location of the connector. The video shows an install on a 2007 Expedition, but the procedure would be similar on your 2004 model. The connector you are looking for is gray in color.

  • Are Brake Controller Harnesses Available Separately from the Brake Controllers
    Yes, the harnesses are available separately from the controller. If you have a Tekonsha brake controller with the port on the back, you will need part # 3035-P. If you do not have a Tekonsha witht he port on the back, write back and let me know what controller you have and I will find out what connectors if any are available.

    For some applications, it is located underneath and to the left of the steering column above the brake pedal. on others, it can be found beneath the dash, near the center console.

  • No 12V Power to Brake Controller on a 2001 Ford F-250
    If the truck had a factory 7 way installed at the factory, it should be plug and play. If the 7 way was installed at the dealer, it may be missing a fuse or breaker. The 12V trailer charge is a separate circuit. That is to supply power directly from your trucks electrical system to a battery or some electrical system on a trailer. The brake controller is on a circuit by itself. Remove the brake controller plug from the port underneath the dash. Check to see if the pin where the black wire...

  • Where is the Brake Brake Controller Adapter Port on a 1996 Ford F-53 Chassis?
    I have an answer for you. Your vehicle does not have a brake controller port on that chassis. Ford started making break controller ports for the F-53 in 1999. In order to install a brake controller, I recommend hard-wiring into the wiring system of the vehicle.

    It could be a fuse or a relay that you burnt out in your 2014 F-53 Hurricane Motorhome. I would recommend you check the owners manual of the MH to determine where all of the tow package fuses and relays are and check them. It can be hard to determine if a relay is bad. If you find the relay for the circuit that is not working but are unsure if it is bad the easiest way to test it is to put a good working relay in its place and if the circuit works at that point you know the relay was bad.
