Cruise Control
Provides information about the selected speed to the engine control module (ECM) which calculates and requests the throttle angle of the electronic throttle module.
Clutch pedal sensor and brake pedal sensor send signals about clutch or brake pedal depression to disconnect the cruise control and control the throttle.
The brake light switch is an extra safety switch for the brake pedal sensor and travels via the engine control module (ECM) directly to the electronic throttle module.
