A proportional brake controller like the Tekonsha Prodigy P2 Brake Controller, part # 90885 applies power to the trailer brakes in proportion to the vehicles braking action. The setup of a proportional brake controller is a simple procedure.

When the brake controller is installed in your 2010 Ford F-150 you will need to first adjust the power to the trailer brakes. The steps to adjust the power are as follows.

1. Connect trailer to tow vehicle.
2. With engine running, hold manual full left and set Power Knob to indicate approximately 6.0
3. Drive tow vehicle and trailer on a dry level paved surface at 25 mph and fully apply manual knob. If trailer brakes lock up, turn power down using power knob. If braking was not sufficient, turn power up using power knob.
4. Repeat step 3 until power has been set to a point just below wheel lock up or at a sufficient force as to achieve maximum braking power.

After the power adjustment is made you will be ready to use your brake controller. Depending on what you will be towing, if you will be needing a more aggressive setting for your trailer brakes you can adjust the boost setting after the initial power adjustment has been made.

I am including a link to the instructions on the Prodigy P2 brake controller that will describe how to adjust the power and the boost.
