Illumination/System Description

Illumination System: Chart:

Power is supplied at all times
^ through 15 A fuse (No. (23) located in the fuse block)
^ to lighting switch terminal (11).
The lighting switch must be in the PARK or HEAD position for illumination.
The illumination control switch is a thumbwheel that controls the amount of current to the illumination system. As the amount of current increases, the illumination becomes brighter.
The ashtray illumination and the glove box lamp are not controlled by the illumination control switch. The intensity of these lamps does not change.
The following chart shows the power and ground connector terminals for the components included in the illumination system.
With the exception of the glove box lamp and the ashtray illumination, the ground for all of the components are controlled through terminals (4) and (5) of the illumination control switch and body grounds (M51), (M76) and (M77).
When the glove box is open, glove box lamp terminal (a) is grounded through the glove box lamp switch and body grounds (M51), (M76) and (M77).
The ashtray illumination terminal (a) is grounded directly through body grounds (M51), (M76) and (M77).
