Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
Features:
This adapter plugs into the built-in connector beneath your vehicle's dashboard. To access this connector, first locate the instrument cluster finish panel in the center of you dash, near the driver's side. Carefully pry the panel out and undo the locking tabs to remove the panel. Plug the adaptor into the mating connector in the large gray housing behind the panel.
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.

Great item, fit exactly, very fast shipping!
This adapter plug was worth every penny, it saved so much time and work!
easy to install with very percise direction on how to use
Worked great even though the correct product was out for an extended period of time
WOW This only took me 15 minutes to install. Plug & Play
Easy to install with great video and "Expert Advice."
Couldn''t be easier!!! Great adapter and for the money, it is not worth taking a chance of having a bad crimp when you make your own connections.
This made my F-150 installation go very quickly.
The wire harness the website recommended worked as advertised. The video was easy to follow and I was able to hook everything up exactly as the video showed. A+
Easy uses after removing dummy plug installed in Ford wire harness on vehicel
This harness made the install plug and play. It took me 10 minutes to install the brake controller
Excellant product. Fast delivery. Easy to install with instructions provided. Just a plug and play type install.
wire harness makes for very easy install also there is no need to splice wires. just plug and go.
The product arrived just as promised. It installed easily. The instructions were spot on. Installed it along with the brake controller and everything seems to work as it should. We will be moving the trailer this next week. I expect there to be no problems.
The wiring harness plugs right onto the factory wiring plug in the F-150, and then into the brake controller. It couldn't be easier! Save yourself some work and frustration, and get the factory wiring pigtail. It makes for a correct, neat, trouble-free install!
This wiring harness works as advertised, plugged right into my 2010 F150 and P3 controller. I reused my controller instead of paying 300+ for the built in one t be installed.
Only thing I think they could do better is use heat shrink at the ends of the wire loom instead of electrical tape.
My new controller showed up earlier than expected. I installed it exactly like the site showed - couldn't have been easier. I picked up my new trailer the next day. The mechanic at the trailer place looked at my new Prodigy 2 controller and told me I picked the right one. Great information, products and service. I highly recommend etrailer.
Great communications, kept me up to date on my order and shipping. I will buy from etrailer again.
The brake controller is outstanding. Easy to set-up, works perfect. The 2009 f150 install video needs to be updated for newer trucks. My 2012 is different.
I installed a Tekonsha brake controller in a 1992 Ford F-150. etrailer had the Tekonsha controller , the wiring kit and excellent information on installation. Shipping was fast too. I just purchase an adapter cable to install the Tekonsha contoller on a new F-150. It was the right product at a great price and again the shipping and service was excellent. Anytime I need anything regarding towing and trailers, I look at etrailer first.
I purchased the Tekonsha P3 brake controller with wire adapter. The install was quite easy.
Item Purchased: Tekonsha P3 Controller and OEM Cable for 2010 F150 Ford Lariat
