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.

the stop lamp switch. A 15 amp fuse in the PDC pro-
tects circuit F32.
When the operator presses the brake pedal, the
stop lamp switch CLOSES and connects circuit F32
to circuit L50. Circuit L50 connects to the stop
lamps. Circuit L50 also splices to power the CHMSL
lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the stop lamps,
CHMSL lamp, and the stop lamp switch. The Z1 cir-
cuit has more than one grounding point. It also sup-
plies ground path for the tail lamps, parking lamps,
headlamps, side marker lamps, rear license plate
lamp, back-up lamps and turn signals.

ing point is in the left front inner fender shield.
BACK-UP LAMPS
In the RUN position, the ignition switch connects
circuit A2 from the Power Distribution Center (PDC)to circuit A22. Circuit A22 feeds a bus bar in the fuse
block. A 40 amp fuse in the PDC protects the A2 and
A22 circuits.
Circuit F20 is one of four circuits that connects to
the fuse block bus bar fed by circuit A22. Circuit F20
supplies power to the back-up lamp switch. On 3±spd
automatic transaxle vehicles, the back-up lamp
switch is part of an assembly that includes the park/
neutral position switch.
When the operator puts the transmission in
REVERSE, the back-up lamp switch connects circuit
F20 to circuit L1. Circuit L1 feeds the back-up lamps.
A 10 amp fuse, in cavity 8 of the fuse block, protects
F20 and L1 circuits.
