Brake On/Off (BOO) Switch

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

BOO switch is wired to brakelight circuit. It signals the PCM when the brake is applied. The BOO input is used to adjust engine idle when A/C is in use and to control torque converter clutch lock/unlock strategy.
