Illumination

Power is supplied at all times:
^ through 15 A fuse (No. (66) located in the fuse and fusible link box)
^ to lighting switch terminal (11)
The lighting switch must be in the 1ST or 2ND position for illumination.
Power is also supplied at all times
^ through 7.5 A fuse (No. (40) located in the fuse block (J/B))
^ to vanity mirror illumination terminal (1)
A variable resistor is built in the illumination control switch to control the amount of current to the illumination system.

The ashtray, clock, vanity mirror illumination and the glove box lamp are not controlled by the illumination control switch. The brightness of these lamps does not change.
The following chart shows the power and ground connector terminals for the components included in the illumination system.
