POWER DISTRIBUTION
DESCRIPTION
All of the electrical current distributed throughout
this vehicle (except for police package wiring used
with rear fuse block) is directed through the stan-
dard equipment Power Distribution Center (PDC).
The molded plastic PDC housing is located in the left
front corner of the engine compartment, just in front
of the coolant reservoir bottle. The PDC housing has
a molded plastic cover. The PDC cover is easily
removed for service access and has a convenient fuse
and relay layout label affixed to the inside surface of
the cover to ensure proper component identification.
The PDC housing is secured in the engine compart-
ment by one screw to the rear of the PDC and two
clips on the front side. A small molded plastic protec-
tive cover on the front right side of the engine com-
partment is unsnapped to access the battery/
generator cable input connection studs.
Included in the police package is an additional rear
fuse block and remote rear power post.
The rear fuse block is located in the right corner of
the trunk behind the trunk trim panel. The rear fuse
block houses 2 relays and three fuses. The wiring is
routed to an area just below the instrument panel in
a six cavity connector to provide three fused ignition
feeds. Three fused battery feeds in the PDC also are
provided to the center stack area of the instrument
panel within the same six cavity connector.
Only the police package has both fused ignition
and battery circuits below the instrument panel. Spe-
cial service vehicles have only the three fused battery
circuits in the six cavity connector.

corner of the trunk side panel.
CAUTION: DO NOT USE THE REMOTE REAR
POWER POST AS A REMOTE JUMP POST. SERI-
OUS DAMAGE CAN OCCUR. REFER TO LUBRICA-

OPERATION
The power distribution system for this vehicle is
designed to provide safe, reliable, centralized and
convenient to access distribution of the electrical cur-
rent required to operate all of the many standard
and optional factory-installed electrical and electronic
powertrain, chassis, safety, comfort and convenience
systems. At the same time, these systems were
designed to provide centralized locations for conduct-
ing diagnosis of faulty circuits, and for sourcing the
additional current requirements of many aftermarket
vehicle accessory and convenience items.
These power distribution systems also incorporate
various types of circuit control and protection fea-
tures, including:
• Fuses
• Fuse cartridges
• Fusible links
• Automatic resetting circuit breakers
• Relays
• Flashers
• Timers
• Circuit splice blocks.
