Brake On-Off (BOO) Switch

WARNING: This page is about a different car, the 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

BOO switch is mounted on the brake pedal. Switch is closed when brake pedal is depressed. Lock-up torque converter uses this signal and is a factor in air/fuel ratio adjustment.
