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 standard equip-
ment 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 res-
ervoir 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 compartment by one screw to the
rear of the PDC and two clips on the front side. A small
molded plastic protective cover on the front right side of
the engine compartment is unsnapped to access the bat-
tery/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.
The remote rear power post is located in the right
corner of the trunk side panel.

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.
The power distribution system for this vehicle con-
sists of the following components:
• Power Distribution Center (PDC)
