GENERAL INFORMATION
INTRODUCTION
The headlamp switch has 3 positions, ON, PARK
(parking lights) and OFF. Two circuits, L2 and L20
connect the headlamp switch to the headlamp dim-
mer/optical horn switch located in the multi-function
switch. The multi-function switch feeds the low and
high beams of the headlamps.
DESCRIPTION AND OPERATION
PARKING LAMPS
Circuit A3 in the Power Distribution Center (PDC)
connects to a bus bar in the fuse block. One of the
four circuits powered by the bus bar is circuit F33.
Circuit F33 connects to the headlamp switch. A 40
amp fuse in the PDC protects the A3 circuit. A 15
amp fuse, in cavity 2 of the fuse block, protects the
F33 circuit.
The headlamp switch has 3 positions, ON, PARK
(tail lamps) and OFF, plus a dimmer switch. When
the headlamp switch is in the PARK or ON position,
the switch connects circuit F33 to circuit L7. From
the headlamp switch, circuit L7 branches to power
the front parking lamps and rear tail lamps, lavalier
lamps, side marker lamps, and rear license plate
lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the parking lamps,
headlamps, lavalier lamps, tail lamps, side marker
lamps and rear license plate lamp although different
grounding points are used. Circuit Z1 also provides
the ground path for the headlamps and turn signals.
HELPFUL INFORMATION
²Check for a blown 40 amp fuse in the PDC.
²Check for a blown fuse in cavity 2 of the fuse
block.
²For the left front parking lamp, turn signal, side
marker lamp and left headlamp, the Z1 circuitgrounding point is the left side of the radiator closure
panel.
²For the right front parking lamp, turn signal,
side marker lamp and right headlamp, the Z1 circuit
grounding point is in the right fender side shield.
²Circuit L7 also feeds the radio, if equipped.
²When the headlamp switch is in the PARK or
ON position, the dimmer circuit, F33, also connects
to circuit E1. Circuit E1 powers the ash receiver
lamp, transmission range indicator lamp, instrument
panel cluster illumination lamps, HVAC control
lamp, heated rear window lamp, and radio lamp. A 4
amp fuse, in cavity 12 of the fuse block, protects cir-
cuit E1.
HEADLAMPS
The headlamp switch has 3 positions, ON, PARK
(parking lights) and OFF. Two circuits, L2 and L20
connect the headlamp switch to the headlamp dim-
mer/optical horn switch located in the multi-function
switch. The multi-function switch feeds the low and
high beams of the headlamps.
HEADLAMP SWITCH IN OFF OR PARKING
LAMP POSITION
Circuit A3 originates in the Power Distribution
Center (PDC) and supplies battery voltage for the
headlamp switch. A 40 amp fuse protects the A3 cir-
cuit. The headlamp switch has an internal 24 amp
circuit breaker that connects circuit A3 to either the
L2 or L20 circuits, depending on switch position.
In the OFF and PARK positions the headlamp
switch feeds the L20 circuit that connects to the
multi-function switch. Circuit L20 powers the high
beam circuit when the operator flashes the head-
lamps with the turn signal stalk of the multi-func-
tion switch. When the operator flashes the
headlamps with the stalk, the multi-function switch
connects the L20 circuit to the L3 circuit. The L3 cir-
cuit feeds the high beam of the headlamps.
HEADLAMP SWITCH IN ON POSITION
When the headlamp switch is in the ON position,
it connects the A3 circuit from the PDC to circuit L2.

DESCRIPTION AND OPERATION
TAIL LAMPS AND LICENSE LAMPS
Circuit A3 in the Power Distribution Center (PDC)
connects to a bus bar in the fuse block. One of the
four circuits powered by the bus bar is circuit F33. A
40 amp fuse in the PDC protects the A3 circuit. A 15
amp fuse, in cavity number 2 of the fuse block, pro-
tects the F33 circuit.
The headlamp switch has 3 positions, ON, PARK
(tail lamps) and OFF, plus a dimmer switch. When
the headlamp switch is in the PARK or ON position,
it connects circuit F33 to circuit L7. From the head-
lamp switch, circuit L7 branches to power the front
parking lamps, rear tail lamps, side marker lamps,
and rear license plate lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the tail lamps, park-
ing lamps, headlamps, side marker lamps, lamps and
rear license plate lamps although different grounding
points are used. Circuit Z1 also provides the ground
path for the headlamps, stop lamps and turn signals.
HELPFUL INFORMATION
²Check for a blown 40 amp fuse in the PDC.
²Check for a blown fuse in cavity 2 of the fuse
block
²For the left rear parking lamp, turn signal, side
marker lamp, and the rear license plate the Z1 cir-
cuit grounding point is in the left rear wheel well.
²For the right rear parking lamp, turn signal and
side marker lamp, the Z1 circuit grounding point is
in the right rear wheel well.
²Circuit L7 also feeds the radio, if equipped.
²When the headlamp switch is in the PARK or
ON position, the dimmer circuit, F33, connects to cir-
cuit E1. Circuit E1 powers the ash receiver lamp,
transmission range indicator lamp, instrument panel
cluster illumination lamps, HVAC control lamp,
heated rear window lamp, and radio lamp. A 4 amp
fuse, in cavity 12 of the fuse block, protects circuit
E1.
FOG LAMPS (REAR)
The rear fog lamps will operate only when the
headlamp switch is in the ON position.
Circuit A3 from the Power Distribution Center sup-
plies (PDC) voltage to a bus bar in the fuse block.
Circuit F61 is one of four circuits that the bus bar
feeds and is protected by a 20 amp fuse in cavity 4.
Circuit F61 connects to the rear fog lamp switch and
the front fog lamp relay.
The fog lamp switch contains a relay that supplies
voltage to the fog lamps. Circuit L2 from the multi-
function switch supplies voltage to the coil side of the
relay (only when the headlamps operate on LOW
beam). Circuit F61 supplies voltage to the contact
side of the relay. During LOW beam headlamp oper-
ation when the fog lamp switch contacts CLOSE, cir-
cuit F61 connects to circuit L38.
Circuit L38 feeds right and left fog lamp. Circuit
L38 also feeds the green L.E.D. in the switch that
illuminates during fog lamps operation.
When the headlamp switch is in the PARK or ON
position, circuit E1 from the headlamp switch sup-
plies voltage for circuit E2. Circuit E2 contains a 4
amp fuse in cavity 12 of the fuse block, and powers
the bulb in the fog lamp switch.
GROUND CIRCUIT
Although circuit Z1 provides the ground path for
the fog lamps, the circuit has different grounding
points for each lamp.
Circuit Z3 supplies the ground path for the fog
lamp switch. The grounding point for the headlamp
switch is the instrument panel left center support.
HELPFUL INFORMATION
²Circuit Z1 also supplies ground for side marker
lamps, turn signals, parking lamps and headlamps.
²Circuit A3 from the PDC supplies voltage to the
headlamp switch for circuit L2.
²Circuit F33 from the fuse block supplies voltage
to the headlamp switch for circuit E1. Circuit A3
from the PDC supplies voltage to a bus bar in the
fuse block that feeds the F33 circuit. Fuse 2, in the
fuse block, protects the F33 circuit.
