OPERATION
All of the circuits entering and leaving the fuse
block do so through the instrument panel wire har-
ness. Internal connection of all of the fuse block cir-
cuits is accomplished by an intricate combination of
hard wiring and bus bars. Internal relays and micro
processors allow the vehicle electronics to control
some of the power distribution circuits throughout
the vehicle. Refer to the Wiring section for complete
circuit diagrams.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove fuse block cover by rotating locking
screw 90É.
(3) Remove the steering column cover. Refer to the
Body section for the procedure.
(4) Unscrew fuse block connections and disconnect
all electrical connectors from the fuse block.
(5) Remove the fuse block from the steering col-
umn.
INSTALLATION
(1) Position the fuse block in the steering column.
(2) Install fuse block connections and connect all
electrical connectors on the fuse block.
(3) Install the steering column cover. Refer to the
Body section for the procedure.
(4) Install fuse block cover by rotating locking
screw 90É.
(5) Connect the negative battery cable.
(6) Set time and radio stations.
FUSE BLOCK #2
DESCRIPTION
An electrical fuse block is concealed under the
driver side front seat. The fuse block serves to dis-
tribute electrical current to many of the electrical
systems in the vehicle. The fuse block houses blade-
type mini fuses, blade-type automatic resetting cir-
cuit breakers and International Standards
Organization relays. Additional provisions are avail-
able in the fuse block for additional fuses and ISO
relays.
The molded plastic fuse block housing has an inte-
gral mounting bracket that is secured with screws to
the seat base. The driver side seat base also has a
snap-fit fuse access panel that can be removed for
service of the fuses and the relays. A finger recess is
molded into one end for easy removal. A fuse layout
map is molded onto the back side of the panel to
ensure proper fuse identification.
The fuse block is integral to the body wire harness.
If any internal circuit or the fuse block housing isfaulty or damaged, the entire fuse block and body
wire harness unit must be replaced.
OPERATION
All of the circuits entering and leaving the fuse
block do so through the body wire harness. Internal
connection of all of the fuse block circuits is accom-
plished by an intricate combination of hard wiring
and bus bars.
POWER DISTRIBUTION CEN-
TER
DESCRIPTION
All of the electrical current distributed throughout
this vehicle is directed through the Power Distribu-
tion Center (PDC). The molded plastic PDC housing
is located in the left front corner of the engine com-
partment, on the battery positive cable. The PDC
housing has a molded plastic cover that slides over
the PDC housing. The PDC cover is easily opened or
removed for service access.
The PDC unit cannot be repaired and is only ser-
viced as a unit with the headlamp and dash wire
harness. If the internal circuits or the PDC housing
are faulty or damaged, the headlamp and dash wire
harness unit must be replaced.
OPERATION
All of the current from the battery and the gener-
ator output enters the PDC through the positive bat-
tery cable. The PDC cover is removed to access the
battery and generator output connection B(+) termi-
nal studs. Internal connection of all of the PDC cir-
cuits is accomplished by an intricate combination of
hard wiring and bus bars. Refer to Wiring Diagrams
for the location of complete PDC circuit diagrams.
POWER OUTLET
DESCRIPTION
The power outlet is installed in the instrument
panel accessory switch plate, which is located near
the center of the instrument panel. The power outlet
base is secured by a snap fit within the instrument
panel. A plastic protective cap snaps over the power
outlet base when the power outlet is not being used.
While the power outlet is very similar to a cigar
lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the recepta-
cle shell that are used to secure the cigar lighter
heating element to the insulated contact.
The power outlet receptacle unit are available for
service. The power outlet receptacle cannot be
