Cruise Master & Custom Cruise III

The Cruise Master system, used on all 1980---82 models and 1983 Caballero and El Camino, and the Custom Cruise III system, used on 1983---87 models except 1983 Caballero and El Camino, allow the operator to maintain a constant vehicle speed without continually applying foot pressure on the accelerator pedal. Both systems use vacuum to control a servo unit which alters throttle position to maintain the selected speed, release valves and switches which allow the system to be easily disengaged, and dash or steering column switches to control the system. The primary differences between the systems are the manner in which the servo is controlled and the method of sensing vehicle speed.
