Trailer Brake Controller Recommendation for a 2012 Ford Expedition with Factory Tow Package

There basically two types of brake controllers: time delay and proportional. Time delay controllers, like # 39523 that you have referenced, send back a pre-set amount of voltage over a certain amount of time which can be adjusted. It can take some time determining the best set up for any given trailer when using a time delay controller and there is more wear and tear on both the vehicle and the trailer. The benefit is that time-delay controllers do not have many mounting restrictions.

Proportional controllers are what I recommend for any trailer set up. These controllers use an internal accelerometer type device that senses how much the vehicle is braking and sends back the appropriate voltage to the trailer brakes to match the vehicle braking. This is the safest way to stop and it reduces wear and tear on both the vehicle and the trailer. Some proportional controllers have more mounting options than others but are not as versatile in terms of mounting as time delay controllers.

I recommend the Tekonsha P2, # 90885, proportional controller. It is easy to use and easy to set up and is one of the most popular controllers we have carried. It can be mounted a full 360 degrees in the direction of travel and it can be used with electric or electric over hydraulic brakes. For a 2012 Ford Expedition with factory 7-Way connector you will also need wiring harness # 3035-P to plug into the factory port.

I have included some helpful links showing a typical installation, instructions, and an FAQ on brake controllers for you.
