I own a '98 Sable. When you look under the dash at the brake pedal, you will see the typical Ford brake light switch that connects to the brake pedal arm that activates the brake lights. What is the white plastic 'plunger style' arm behind it? It moves with the pressing of the brake pedal too. It appears to be an electric switch of some kind. The wires from it connect to the brake light switch. What is it and what is its purpose??

Turns off the cruise control when the brake pedal is pressed.

Thanks Major. Figured it was either the cruise cancellation or the electrical signal to the floor shifter that allows me to shift when the brake is applied.....hoping it was the later. Thanks again!

The shift interlock (can shift out of park unless brake pressed) signal comes from the brake light switch. Its a great way to tell if you have inop brake ligths due to a switch failure.... you cant shift out of park!

That can be overridden in an emergency by turning the key to the unlock position then shift. Good to know if you're ever stuck in park in a bad area or something. Just be aware you won't have brake lights.
