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

intention is to organize information by system, con-
sistently from year to year.

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-

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.

AUDIO SYSTEM
RADIO
When the ignition switch is in the ACCESSORY or
RUN position, it connects circuit A1 from fuse 6 in the
Power Distribution Center (PDC) to circuit A48. Cir-
cuit A48 powers circuit F85 through fuse 2 in the fuse
block. Circuit F85 powers the radio.
Circuit Z1 provides ground for the radio. The an-
tenna connects to the rear of the radio.
RADIO MEMORY
Circuit M1 from the Ignition Off Draw (IOD) fuse
(fuse 9) in the fuse block supplies power for the radio
memory. The IOD fuse is removed during vehicle
shipping to prevent excessive battery draw.
Circuit A6 from fuse 16 in the Power Distribution
Center (PDC) supplies voltage to fuse 9. Circuit A7
from fuse 3 in the PDC powers circuit A6 through
fuse 16. Circuits A6, A7 and M1 are HOT at all times.
RADIO ILLUMINATION
Circuit E2 supplies battery voltage to the radio
illumination lamps when the headlamps or parking
lamps are on and the dimmer switch is in the LOW or
ON positions.
Circuit X5 supplies battery voltage for the radio
clock and station frequency display. Circuit X5 origi-
nates at the radio illumination relay and is fed by
either circuit F85 or circuit E2 depending on the
switch position inside the relay.
When the headlamps and parking lamps are off, the
radio illumination relay is in its normal At Rest posi-
tion. In the At Rest position, the relay connects circuit
F85 from fuse 2 in the fuse block to circuit X5.
When the headlamps or parking lamps are on, cir-
cuit L90 from the headlamp switch supplies battery
voltage to the coil side of the radio illumination relay.
Circuit Z1 provides ground for the coil side of the
relay.
When voltage is present on circuit L90, the radio
illumination relay switches from its At Rest position
to connect circuit E2 to circuit X5.
SPEAKERS
There are 3 different radio packages. The standard
radio package includes 2 speakers; one in each front
door. The four speaker system uses speakers in each
front door plus speakers in the rear sound bar. The six
speaker system has the front door speakers, sound bar
speakers and two speakers in the instrument panel.
BASE RADIO
Vehicles with the base radio have a jumper between
the radio and the instrument panel connectors. The
jumper simulates rear speaker load.Circuit X53 feeds the speaker in the left front door.
Circuit X55 is the return from the speaker to the
radio.
Circuit X54 feeds the right front door speaker. Cir-
cuit X56 is the return from the speaker to the radio.
FOUR SPEAKER SYSTEM
Circuit X53 feeds the speaker in the left front door.
Circuit X55 is the return from the speaker to the
radio.
Circuit X54 feeds the right front door speaker. Cir-
cuit X56 is the return from the speaker to the radio.
Circuit X51 feeds the left rear speaker. Circuit X57
is the return from the speaker to the radio.
Circuit X52 feeds the right rear speaker. Circuit
X58 is the return from the speaker to the radio.
SIX SPEAKER SYSTEM
Circuit X53 feeds the left speaker in the instrument
panel. The X53 circuit is double crimped at the in-
strument panel left speaker and branches to the left
front door speaker. Circuit X55 is the return to the
radio from the instrument panel left speaker and left
front door speaker. Circuit X55 is double crimped at
the instrument panel left speaker.
Circuit X54 feeds the right speaker in the instru-
ment panel. The X54 circuit is double crimped at the
instrument panel right speaker and branches to the
right front door speaker. Circuit X56 is the return to
the radio from the instrument panel left speaker and
left front door speaker. Circuit X56 is double crimped
at the instrument panel left speaker.
Circuit X51 feeds the left rear speaker. Circuit X57
is the return from the speaker to the radio.
Circuit X52 feeds the right rear speaker. Circuit
X58 is the return from the speaker to the radio.

RADIO
RADIO
When the ignition switch is in the ACCESSORY or
RUN position, it connects circuit A1 from fuse 6 in
the Power Distribution Center (PDC) to circuit A48.
Circuit A48 powers circuit F85 through fuse 13 in the
fuse block. Circuit F85 powers the radio.
Circuit Z1 provides ground for the radio. The an-
tenna connects to the rear of the radio.
RADIO MEMORY
Circuit M1 from fuse 16 in the Power Distribution
Center (PDC) supplies power for the radio memory.
Circuit A7 from fuse 3 in the PDC supplies voltage
to fuse 16. Circuits A7 and M1 are HOT at all times.
RADIO ILLUMINATION
Circuit E2 supplies battery voltage to the radio il-
lumination lamps when the headlamps or parking
lamps are on and the dimmer switch is in the Low or
On positions.
Circuit X5 supplies battery voltage for the radio
clock and station frequency display. Circuit X5 origi-
nates at the radio illumination relay and is fed by ei-
ther circuit F85 or circuit E2 depending on the
switch position inside the relay.
When the headlamps and parking lamps are off,
the radio illumination relay is in its normal At Rest
position. In the At Rest position, the relay connects
circuit F85 from fuse 13 in the fuse block to circuit
X5.
When the headlamps or parking lamps are on, cir-
cuit L90 from the headlamp switch supplies battery
voltage to the coil side of the radio illumination relay.
Circuit Z1 provides ground for the coil side of the re-
lay.
When voltage is present on circuit L90, the radio
illumination relay switches from its At Rest position
to connect circuit E2 to circuit X5.
HELPFUL INFORMATION
²Circuit A48 supplies voltage to fuse 13 in the fuse
block for circuit F85 when the ignition switch is in
the ACCESSORY or RUN positions. In these posi-
tions, the ignition switch connects circuit A1 from
fuse 6 in the PDC to circuit A48.²Circuit A3 from fuse 5 in the PDC supplies power
to the fuse block for fuse 9. Fuse 9 protects circuit
L7. When the headlamps or parking lamps are ON,
the headlamp switch connects circuit L7 to circuit
L90. When the adjustable dimmer switch is in the
LOW to ON positions, it internally connects circuit
L7 to circuit E2. Circuit E2 powers fuse 25 in the
fuse block. Circuit E2 continues through fuse 25.
POWER ANTENNA
The Power Antenna Relay supplies power to raise
and lower the antenna. Circuit F60 from fuse 7 in
the fuse block powers the relay. Circuit Z1 provides
ground for the relay.
When the radio is turned on, circuit X60 from the
radio energizes the relay to raise the antenna.

Circuit X53 feeds the left front speakers. Circuit
X55 is the return from the speakers to the radio.
Circuit X54 feeds the right front speakers. Circuit
X56 is the return from the speakers to the radio.
