HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou-
bleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wir-
ing which is not part of the circuit represented is ref-
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo-
nents, and modules are shown in theat rest posi-
tion with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system.
It is important to realize that no attempt is
made on the diagrams to represent components
and wiring as they appear on the vehicle. For
example, a short piece of wire is treated the
same as a long one. In addition, switches and
other components are shown as simply as pos-
sible, with regard to function only.
The wiring diagram show circuits for all wheel-
bases. If there is a difference in systems or compo-
nents between wheel-bases, an identifier is placed
next to the component.
SECTION IDENTIFICATION
Sections in Group 8W are organized by sub-sys-
tems. The sections contain circuit operation descrip-
tions, helpful information, and system diagrams. The
intention is to organize information by system, con-
sistently from year to year.
CONNECTOR LOCATIONS
Section 8W-90 contains Connector Location illus-
trations. The illustrations contain the connector
number and component identification. Connector Lo-
cation charts in Section 8W-90 reference the illustra-
tion number for components and connectors.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the number on the Diagram
pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.

IGNITION SWITCH
Circuit A1 from fuse 4 in the Power Distribution
Center (PDC), supplies battery voltage to the ignition
switch. Depending upon position, the ignition switch
powers circuits A21, A22, A31, and A41.
START POSITION
In the START position, the ignition switch connects
circuit A1 to circuit A41. Circuit A41 connects to the
coil side of the starter motor relay.
Also in the START position, the case grounded ig-
nition switch provides ground for the brake lamp
switch and parking brake lamp switch on circuit G11.
START OR RUN POSITION
In the START and RUN position, the ignition

HEADLAMPS
The headlamp switch has three positions: ON,
PARK (parking lamps) and OFF. Two circuits, L2 and
L20, connect the headlamp switch to the headlamp
dimmer/optical horn switch. The dimmer switch feeds
the low and high beams of the headlamps.
HEADLAMP SWITCH IN OFF OR PARKING
LAMP POSITION
Circuit A3 from fuse 7 in the Power Distribution
Center (PDC) supplies battery voltage to the head-
lamp switch. The headlamp switch has an internal
circuit breaker that connects circuit A3 to circuit
L20. The switch connects circuit A3 to circuit L2
when the headlamps are ON.
Circuit L20 connects to the dimmer switch. Circuit
L20 powers the high beams of the head lamps on cir-
cuit L3 when the operator flashes the headlamps
with the turn signal stalk.
HEADLAMP SWITCH IN ON POSITION
When the headlamp switch is in the ON position,
the A3 circuit from the PDC connects to circuit L2.
Circuit L2 connects to circuit L4 through the dimmer
switch. Circuit L4 powers the low beam of the head-
lamps.
When the operator selects high beam operation
with the turn signal stalk, the dimmer switch con-
nects circuit L20 to circuit L3. Circuit L3 supplies
battery voltage to the high beams.
HEADLAMP GROUND
Although circuit Z1 provides ground for both the
right and left headlamps, it has different termination
points for each. For the right headlamp, the Z1 cir-
cuit terminates at the radiator right support. For the
left headlamp, the Z1 circuit terminates at the left
radiator support.
HELPFUL INFORMATION
²Check fuse 7 in the PDC.
²The headlamp switch has an internal circuit
breaker.
²For the left front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the left radiator support.²For the right front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the right radiator support.
PARKING LAMPS
Circuit A6 from fuse 3 in the Power Distribution
Center (PDC) connects to the fuse block bus bar that
powers circuit F33. Fuse 8 in the fuse block protects
circuit F33. Circuit F33 connects to the headlamp
switch.
The headlamp switch has three positions: ON,
PARK (parking lamps) and OFF, plus a dimmer
switch. When the headlamp switch is in the PARK or
ON position, the switch connects circuit F33 to cir-
cuit L7. From the headlamp switch, circuit L7
branches to power the front parking lamps, rear tail
lamps, and side marker lamps. Circuit L7 also pow-
ers the park lamp relay, if equipped with fog lamps.
GROUND CIRCUIT
²For the left front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the left radiator support.
²For the right front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the right radiator support.
HELPFUL INFORMATION
²Check fuse 3 in the PDC.
²Check fuse 8 in the fuse block.
²Circuit L7 also feeds the radio, if equipped.
FOG LAMPS
The fog lamps are controlled by the fog lamp
switch and two relays. The fog lamps operate only
when the headlamp switch is in the ON position, and
the operator has selected low-beam operation. When
the headlamps are in high-beam operation, the fog
lamps will not operate.
When the headlamps or parking lamps are ON, cir-
cuit L7 from the headlamp switch supplies battery
voltage to the coil side of the park lamp relay. When
the operator presses the fog lamp switch, it provides
ground for the coil side of the park lamp relay. This
energizes the relay.
J8W-50 FRONT LIGHTINGÐYJ VEHICLES 8W - 50 - 1
When the park lamp relay energizes, the relay con-
tacts close and connect circuit F81 from fuse 6 in the
fuse block to circuit L36. Circuit L36 connects to the
contact side of the high beam relay. The contacts in
the high beam relay are normally closed. Battery
voltage flows through high beam relay to the fog
lamps on circuit L39. Circuit L39 also splices to the
lamp in the fog lamp switch.
Circuit L3 from the dimmer switch provides power
for the high beams of the headlamps and connects to
Circuit G34. Circuit G34 powers the coil side of the
high beam relay. Circuit Z1 provides ground for the
coil. When the operator selects high beam operation
or flashes the optical horn, circuit G34 energizes the
high beam relay. When energized, the normally
closed contacts in the relay open, shutting off battery
voltage to the fog lamps on circuit L39.
HELPFUL INFORMATION
²Circuit A6 from fuse 3 in the PDC supplies voltage
to the fuse block for fuses in cavities 3 and 6. Fuse 6
in the fuse block protects circuit F81 which powers
the contact side of the park lamp relay.
²In the high beam position, the dimmer switch con-
nects circuit L20 from the headlamp switch to circuit
L3. The headlamp switch connects circuit A3 from
fuse 7 in the PDC with circuit L20. Circuits A3 and
L20 are HOT at all times.
DAYTIME RUNNING LAMP (DRL) MODULEÐ
CANADIAN VEHICLES ONLY
On Canadian vehicles, the low-beam headlamps op-
erate when the ignition switch is in the RUN position
and the headlamp switch is OFF.
When the ignition switch is in the START or RUN
positions, circuit A1 from fuse 4 in the Power Distri-
bution Center (PDC) connects to circuit A21. Circuit
A21 supplies voltage to circuit G5 through fuse 9 in
the fuse block. Circuit G5 splices to supply battery
voltage to the DRL module.
Circuit L20 from the headlamp switch connects to
the DRL module. Circuit L20 is HOT at all times.
The DRL module receives the vehicle speed sensor
input from circuit G7. Circuit G34 from the DRLmodule provides power for the high beam indicator
lamp in the instrument cluster.
Circuit L4 feeds the low beams of the headlamps.
When the headlamp switch is in the OFF position,
the DRL module powers the left and right headlamps
on circuit L4. When the headlamps are ON, the dim-
mer switch powers the low beams on circuit L4.
Circuit L3 feeds the high beams of the headlamps.
When the operator flashes the high beams with the
turn signal stalk, the DRL senses voltage on circuit
L3. When it senses voltage on circuit L3, the DRL
module stops supplying power to the low beams on
circuit L4.
Circuit Z1 provides ground for the DRL module.
Circuit Z1 terminates at the radiator left side sup-
port.
