Function Checks

Terminal No. 8, of the control unit, must be grounded for cruise control to operate. When the brake pedal is depressed, the brake switch closes and voltage to the brake lights electrically interrupts the ground circuit to the control unit, canceling operation. Power is supplied through fuse No. 5 (8-amp) to terminal No. 1 (control unit), terminal No. 2 (control switch) and terminal No. 1 (speed sensor).
