When the headlamp switch placed in the PARK position battery voltage is supplied through the headlamp switch to both the TAIL LAMP, LIC LAMPS fuse and the FRONT PARK fuse. Battery voltage is then applied through the TAIL LAMP LIC LAMPS fuse and the FRONT PARK fuse to the front and rear park lamps and the rear license lamps illuminating the park lamps.

Battery voltage is then applied thorough the rear park lamp fused circuit to the I/P dimming switch in the headlamp switch. The I/P dimming switch varies the voltage level to the interior lamps, dimming or brightening them accordingly through the I/P dimming switch circuit. The grounds for the interior lamps is applied at all times.
