Cruise Control: Description

System uses manifold vacuum to power a throttle servo unit. When speed adjustment is necessary, servo moves the throttle by receiving a varying amount of controlled vacuum from regulator unit. Speedometer cable from transmission drives regulator and a cable from regulator drives instrument panel speedometer. Engagement of regulator unit is controlled by an engagement switch located at end of turn signal lever or on instrument panel. Two brake release switches are provided. An electric switch disengages regulator unit and a vacuum (switch) valve decreases vacuum in servo unit to quickly return throttle to idle position when brake pedal or clutch is depressed.
