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.

ANTI-LOCK BRAKES
GENERAL INFORMATION
Three fuses supply power for the Anti-Lock Brake
System (ABS); fuses 9 and 10 in the PDC and fuse
13 in the fuse block. Fuses 9 and 10 in the Power
Distribution Center (PDC) are connected directly to
battery voltage and are HOT all times. Fuse 13 is
HOT when the ignition switch is the RUN position.
In the RUN position, the ignition switch connects
circuit A1 from fuse 4 in the PDC with circuit A22.
Circuit A22 connects to a bus bar in the fuse block.
The bus bar feeds circuit F15 through fuse 13. Fuse
13 is a 2 amp fuse.
Circuit F15 splices to the coil side of the ABS
power relay and cavity 53 of the ABS control module.
Circuit Z1 provides ground for the ABS control
module. Circuit Z1 connects to cavities 1 and 19 of
the ABS control module.
Refer to group 5, Brakes for operational descrip-
tions of ABS system components.
WHEEL SPEED SENSORS
The all wheel anti-lock system uses four wheel
speed sensors; one for each wheel. Each sensor con-
verts wheel speed into an electrical signal that it
transmits to the ABS control module. A pair of
twisted wires connect to each sensor to provide sig-
nals to the ABS control module.
Circuits B6 and B7 provide signals to ABS control
module from the right front wheel speed sensor. Cir-
cuit B6, which provides the LOW signal, connects to
cavity 29 of the ABS control module. Circuit B7 con-
nects to cavity 47 of the module and provides the
HIGH signal.
Circuits B8 and B9 provide signals to ABS control
module from the left front wheel speed sensor. Cir-
cuit B8, which provides the LOW signal, connects to
cavity 30 of the ABS control module. Circuit B9 con-
nects to cavity 48 of the module and provides the
HIGH signal.
Circuits B1 and B2 provide signals to ABS control
module from the right rear wheel speed sensor. Cir-
cuit B1 which provides the LOW signal, connects to
cavity 27 of the ABS control module. Circuit B2 con-
nects to cavity 45 of the module and provides the
HIGH signal.
Circuits B4 and B3 provide signals to ABS control
module from the left rear wheel speed sensor. Circuit
B3, which provides the LOW signal, connects to cav-
ity 28 of the ABS control module. Circuit B4 connects
to cavity 46 of the module and provides the HIGH
signal.
ACCELERATION SWITCH
During four-wheel drive operation, the acceleration
switch provides deceleration data to the ABS control
module. Refer to Group 5, Brakes for additional in-
formation.
Circuits B21, B22, and B23 connect the accelera-
tion sensor to the ABS control module. Circuits B21
and B22 provide switch states while circuit B23 pro-
vides ground. At the ABS control module circuit B21
connects to cavity 25, circuit B22 connects to cavity
43 and circuit B23 connects to cavity 26.
ABS POWER RELAY
The ABS power relay is located in the Power Dis-
tribution Center (PDC). When the ABS module
grounds the ABS power relay on circuit B20, the re-
lay switches to connect circuit B15 and circuit A20
from PDC fuse 10. Circuit F15 from fuse 13 in the
fuse block splices to feed the coil side of the ABS
power relay. Circuit B20 connects to cavity 34 of the
ABS control module.
Circuit B15 is double crimped at the ABS power re-
lay. One branch of circuit B15 supplies power to the
coil side of the ABS pump motor relay. The other
branch of circuit B15 splices to cavities 3 and 33 of
the ABS control module and to the hydraulic control
unit.
ABS PUMP MOTOR RELAY
The ABS pump motor relay in the Power Distribu-
tion Center (PDC) supplies voltage to the ABS pump
motor. When the ABS power relay energizes, circuit
B15 supplies battery voltage to the coil side of the
ABS pump motor relay. The ABS control module pro-
vides ground for the relay on circuit B116. Circuit
B116 connects to cavity 15 of the ABS control mod-
ule.
When the ABS pump motor energizes, it connects
circuit A10 from PDC fuse 9 to circuit B25. Circuit
B25 supplies battery voltage to the pump motor. Cir-
cuit Z12 provides ground for the pump motor.
PUMP MOTOR SPEED SENSOR
The input from the pump motor speed sensor tells
the ABS control module that the pump is operating.
Circuit B17 and B16 from the control module connect
to the speed sensor.
BRAKE PEDAL TRAVEL SENSOR
The brake pedal travel sensor provides the ABS
control module with data regarding brake pedal posi-
tion. The sensor is a variable resistor that the ABS
