Operation
The Lighting for Controls wiring diagrams cover instrument
panel and switch illumination. Some of the switches have replaceable bulbs. See 364 Electric Controls and Switches
for information on replacing switch bulbs. See 853 Dashboard and Consoles for information on removing the instrument cluster. See 432 Manual Transmission Controls or
444 Automatic Transmission Controls for details on removing the center console.

Wiring Diagrams, Fuses and Relays

Luggage Compartment Lighting
Operation
The luggage compartment light (55) is controlled by a luggage compartment light switch located behind the left trunk
hinge on sedans and beneath the striker plate on hatchbacks.
With the trunk open, the switch is closed to light the lamp. The
luggage compartment light (55) also has a switch to disable
the light at all times. To change the bulb, pry off the lens. Convertible models use a mercury switch (position sensitive) rather than a mechanical switch.
