When I purchased my 2012 Ford Expedition, it came with a hitch, and a 4-pin trailer connector. There wasn’t a brake controller installed, and I needed a 7-blade connector so I could pull my trailer. Adding the 7-blade connector and brake controller was not complicated. It’s just a matter of picking up the right parts. This article is about adding the brake controller. Also check out my article on Installing to a 7-blade RV connector on a Ford Expedition.
Parts Needed:
Tekonsha Prodigy (Amazon – Tekonsha 90885 Prodigy P2 Electronic Brake Control
Tekonsha Plug-In Wiring Adapter PN 3035-P (Amazon – Tekonsha 3035-P Brake Control Wiring Adapter for Ford
Installing The Brake Controller:
The first thing I did was locate the factory plug Ford provides to install a brake controller
You can see the factory connector hanging under the dash right behind the diagnostic plug that mechanics plug their scan tools in to.
And then I found a place to mount my brake controller:
You can see where I found a wide metal surface under the dash, and used (1) of the factory screws. I drilled the second hole and used a small bolt and nut with a lock washer.
I then attached the brake controller to the mounting bracket.
I had already plugged the Tekonsha wiring adapter in to the brake controller:

About The Author
Growing up, my father always believed that every family needed a truck—there’s just something about having a vehicle capable of hauling anything at a moment’s notice. That philosophy stuck with me, and it’s been the foundation of my lifelong passion for Ford trucks.
While I’m best known for my work with Ford Rangers, I’ve owned a wide variety of Ford trucks over the years—including F-150s, F-250s, F-350s, and even larger rigs like the Ford Excursion, Ford Expedition, and a 1982 Ford Econoline Sportsmobile camper van. I’ve used these vehicles for everything from family transportation to towing car trailers and campers, and each one has fueled my love for Ford’s versatility and durability.
I especially enjoy the styling of 1970s and 1980s Ford trucks—the bold designs, rugged presence, and classic charm are timeless. Sharing my passion for Ford trucks, vans, and SUVs with other enthusiasts online brings me a great deal of joy, and it’s why I created Blue Oval Trucks.
This website is dedicated to helping Ford truck enthusiasts explore, learn about, and celebrate these incredible vehicles. While I share my expertise and experiences here, Blue Oval Trucks is an independent enthusiast site and is not affiliated with Ford Motor Company.
