ILLUMINATION CONTROLLER
Turning the illumination controller knob upward
increases the brightness
of each illumination light,
turning it downward decreases its brightness. The
knob is
installed on the ground circuit of the
illumination lights, turning it changes the resistance
of the controller. (Fig. 8-103)

STOPLIGHT AND REAR DEFOGGER I
GENERAL DESCRIPTION i .-_
The circuit consists of the stoplight, stoplight switch (vehicles w/o cruise control), brake switch (ve~icles w/
cruise control), rear defogger, rear defogger switch, rear defogger relay and trailer harness conn~ctor for
stoplights. i
With the brake pedal depressed, the stoplight switch or the brake switch is turned on to illumi~ate the
stoplight. The brake switch controls not only the operation of the stoplight but also the input of th~ cruise
cancel signals to the cruise control unit. 1
When the rear defogger switch is turned on with the starter switch on, the battery voltage is applie to the
rear
defogger through the rear defogger relay to operate the rear defogger.
The rear
defogger switch is provided with a timer. When the operation time of the timer elapses w ich has
been set in advance at manufacture,
the switch is automatically turned off. (The timer operating time is
normally about 30 minutes).
