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:
