Illumination

System Description:

Power is supplied at all times
^ through 15 A fuse (No. (56), located in the fuse and fusible link box)
^ to tail lamp relay terminal (3) and (1)
Ground is supplied to tail lamp relay terminal (2) when the lighting switch is moved to the 1ST or 2ND position.
The tail lamp relay is energized.
The lighting switch must be in the 1ST or 2ND 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 glove box lamp, cigarette lighter, rear power window sub-switch LH, and rear power window sub-switch RH illumination is not controlled by the illumination control switch. The intensity of these lamps does not change.

The chart shows the power and ground connector terminals for the components included in the illumination system.

With the exception of the glove box lamp, cigarette lighter, rear power window sub-switch LH, and rear power window sub-switch RH illumination, the ground for all of the components are controlled through terminals (3), (4) and (5) of the illumination control switch and body grounds (M14) and (M68).

The glove box lamp terminal (3) and cigarette lighter illumination terminal (1) are grounded directly through body grounds (M14) and (M68).

The rear power window sub-switch LH terminal (33) is grounded directly through body grounds (B9) and (B31). The rear power window sub-switch RH terminal (33) is grounded directly through body grounds (B54) and (B71).
