Console: Description and Operation

The CB-4 TAIL/ILLUMI LIGHT fuse applies battery voltage at all times to the taillight relay. When the lighting switch is in the HEAD or PARK position, the lighting switch provides ground to the taillight relay. The taillight relay energizes, providing battery voltage to the dash and console lights. The brightness of the lights is controlled by the illumination controller. The illumination controller is a solid-state device which controls the ground path provided to the lights.
