OVERHEAD CONSOLE
OVERHEAD CONSOLE
When the ignition switch is in the START or RUN
position, it connects circuit A1 from fuse 6 in the
Power Distribution Center (PDC) to circuit A21. Cir-
cuit A21 supplies power to circuit F87 through fuse
17 in the fuse block. Circuit F87 supplies power to
the overhead console.
When the headlamps or parking lamps are ON, cir-
cuits L90 and E2 provide voltage to the overhead
console for illumination. Voltage on circuit L90 in-
forms the overhead console that the headlamps or
parking lamps are ON. Circuit E2 from fuse 19 in
the fuse block powers the illumination lamps in the
overhead console. Circuit E2 originates at the head-
lamp switch.
Circuits Z1 and Z2 provides ground for the over-
head console. From circuit M2, the overhead console
senses when one of the door jamb switches opens.
AMBIENT TEMPERATURE SENSOR
The ambient temperature sensor is a variable re-
sistor. Circuit G31 supplies voltage from the over-
head console to the sensor. Circuit G32 is the signal
return from the sensor to the overhead console.
LAMPS
Circuit M1 supplies voltage for the case grounded
reading lamps in the overhead console. The ignition
off draw (IOD) fuse (fuse 9) in the fuse block supplies
voltage to circuit M1. Circuit A6 from fuse 16 in PDC
feeds the IOD fuse. Circuit A7 from fuse 3 in the
PDC supplies voltage to fuse 1 in the PDC.

OVERHEAD CONSOLE
OVERHEAD CONSOLE
When the ignition switch is in the START or RUN
position, it connects circuit A1 from fuse 6 in the
Power Distribution Center (PDC) to circuit A21. Cir-
cuit A21 supplies power to circuit F87 through fuse
26 in the fuse block. Circuit F87 supplies power to
the overhead console.
When the headlamps or parking lamps are ON, cir-
cuits L90 and E2 provide voltage to the overhead
console for illumination. Voltage on circuit L90 in-
forms the overhead console that the headlamps or
parking lamps are ON. Circuit E2 from the head
lamp switch powers the illumination lamps in the
overhead console. Circuit E2 also powers fuse 25 in
the fuse block.
Circuits Z1 and Z2 provides ground for the over-
head console. From circuit M2, the overhead console
senses when one of the door jamb switches opens.
AMBIENT TEMPERATURE SENSOR
The ambient temperature sensor is a variable re-
sistor. Circuit G31 supplies voltage from the over-
head console to the sensor. Circuit G32 is the signal
return from the sensor to the overhead console.
LAMPS
Circuit M1 supplies voltage for the case grounded
reading lamps in the overhead console. Fuse 16 in
the Power Distribution Center (PDC) supplies volt-
age to circuit M1 through circuit A7. Circuit A7 from
fuse 3 in the PDC supplies voltage to fuse 16 in the
PDC.
