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.

GENERAL INFORMATION
Circuit M1 supplies power to the glove box lamp,
left courtesy lamp, right courtesy lamp, dome lamp,
and cargo lamp. The M1 circuit also connects to the
remote keyless entry module. Circuit M1 is protected
by the ignition off draw (IOD) fuse (fuse 9) in the fuse
block.
Circuit E2 supplies power for the instrument panel
illumination lamps.
INSTRUMENT PANEL ILLUMINATION LAMPS
Circuit E2 from the headlamp switch splices to
supply power to the following illumination lamps:
²Ash receiver lamp
²Cigar lighter lamp
²Transmission range indicator lamp
²Transfer case range indicator lamp
²A/C-Heater switch lamp
²Heated rear window lamp
²Rear wiper switch lamp
²Fog lamp switch lamp
Fuse 19 in the fuse block protects circuit E2. Circuit
Z1 provides ground for all of the illumination lamps
except for the cigar lighter lamp. The cigar lighter
lamp is case grounded.
HELPFUL INFORMATION
Circuit E2 also supplies power to the radio, LCD
relay and the illumination lamps in the instrument
cluster.
IGNITION SWITCH LAMP
The time delay relay is used to allow a time-ON
function for the ignition switch lamp and the courtesy
lamp. Power for the relay is received on the M1
circuit from the IOD fuse (fuse F9) in the fuse block.
Circuit M2 provides ground for the time delay relay
through the right and left door ajar switches and the
headlamp switch. When a door is opened, or the
headlamp switch is moved to the dome lamp position,a ground path is provided for the relay on circuit M2.
This energizes the relay, causing the contacts to close.
When the relay contacts close, power is provided
through the relay to circuit M50. The M50 circuit
supplies current to the ignition switch lamp. Circuit
Z1 provides ground for the lamp.
GLOVE BOX LAMP
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block powers the glove box lamp. A case grounded
switch, in series after the lamp, closes when the glove
box door is opened. The switch completes a path to
ground on circuit Z1.
CARGO LAMP, COURTESY LAMPS AND DOME
LAMP
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block supplies power to the cargo, courtesy lamps and
dome lamp. This circuit is HOT at all times. The
ground path for the lamp is provided in three differ-
ent ways.
One way is through the door jamb switches. Circuit
M2 connects to the door jamb switches from the cour-
tesy and dome lamps. The switches are connected to
ground circuit Z1. When a door is opened, the plunger
in the switch closes, completing a path to ground.
The second way is through the liftgate switch. Cir-
cuit M2 connects to circuit M4 at the cargo lamp.
Circuit M4 connects to the liftgate switch. The lift-
gate switch connects to ground circuit Z1. When the
lift gate opens, the plunger in the switch closes, com-
pleting a path to ground.
The third ground path is through the headlamp
switch. Circuit M2 is spliced in with the headlamp
switch. When the operator turns the headlamp switch
to the dome lamp ON position, a ground path is
provided through the switch.
J8W-44 INTERIOR LIGHTINGÐXJ VEHICLES 8W - 44 - 1
READING LAMPS
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block supplies power to the reading lamps. Circuit
M1 is HOT at all times. When the operator depresses
the reading lamp, the reading lamp switch closes and
supplies ground on circuit Z1.
VISOR VANITY MIRROR LAMPS
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block supplies power to the vanity lamps. Circuit M1
is HOT at all times. When the vanity lamps switch
closes, voltage flows to vanity mirror lamps. The van-
ity mirror is case grounded.
UNDERHOOD LAMP
Circuit A6 from fuse 16 in the Power Distribution
Center (PDC) supplies battery voltage for the under-
hood lamp. A mercury switch, in series after the
lamp, connects the lamp to ground on circuit Z1.
When the hood is raised, mercury inside the switch
moves to a position where it connects circuit M1 to
ground circuit Z1, illuminating the lamp.
CHIME/BUZZER MODULE
The buzzer or optional chime module sounds an au-
dible warning tone. The tone sounds for seat belt
warning and when the ignition key is in the ignition
switch while the drivers door is open. The tone also
sounds when the ignition key is in the ON position
while the drivers side seat belt is not buckled. Lastly,
the tone sounds when the headlamps are ON when
the ignition is OFF. Refer to Group 8U for system op-
eration.
When the ignition switch is in the RUN or START
position, circuit F87 from fuse 17 in the fuse block
supplies power to the chime/buzzer module. Circuit
A21 from the ignition switch supplies power to fuse
17.
Circuit L7 from fuse 15 in the fuse block also sup-
plies power to the chime/buzzer module. Circuit A3
from fuse 5 in the Power Distribution Center (PDC)
powers fuse 15.
When the parking lamps or headlamps are ON, the
headlamp switch connects circuit G26 with the driv-
ers side door jamb switch. Circuit G26 also connects
to the key-in switch. Circuit M11 connects the key-in
switch to the chime/buzzer module and the headlamp
switch.
If the headlamps are ON, and the drivers door
opens, ground for the chime/buzzer is on circuit C26
from the headlamp switch through the door jamb
switch to circuit Z1.
If the headlamps are OFF with the key in the ig-
nition while the drivers side door is open, ground forthe chime/buzzer is supplied through the key-in
switch. The ground path is over circuit M11, through
the closed key-in switch to circuit C26. From circuit
C26, the ground path continues through the drivers
door jamb switch to circuit Z1.
Circuit G11 from the buzzer powers the seat belt
warning lamp in the instrument cluster. Circuit Z1
at the instrument cluster provides ground for the
lamp.
Circuit G10 from the buzzer connects to the seat
belt switch. When the seat belt switch closes a path
to ground is completed on circuit Z1 and the tone
sounds momentarily.
Circuit Z1 also grounds the chime\buzzer module.
HELPFUL INFORMATION
Circuit F87 also powers the instrument cluster and
the headlamp delay module.
