POWER DISTRIBUTION
CENTER
DESCRIPTION
All of the electrical current distributed throughout
this vehicle is directed through the standard equip-
ment Power Distribution Center (PDC) (Fig. 7). The
molded plastic PDC housing is located on the right
side of the engine compartment, forward of the bat-
tery on the top of the right front inner fender shield.
The PDC houses up to fifteen maxi-type cartridge
fuses, which replace all in-line fusible links. The PDC
also houses up to thirteen blade-type mini fuses, and
up to twelve International Standards Organization
(ISO) relays (four standard-type and eight micro-
type).

The PDC housing is secured in the engine compart-
ment at four points. Integral mounts on both sides of
the PDC housing engage and latch to stanchions that
are integral to the stamped steel PDC bracket. The
PDC bracket is secured to the top of the right front
inner fender shield with three screws, two at the
front of the bracket and one at the rear. The PDC is
integral to the dash wire harness, which exits from
the bottom of the PDC housing. The PDC housing
has a molded plastic cover that includes two integral
latches at the rear and pivot hooks at the front that
snap over a hinge pin on the front of the PDC hous-
ing. The PDC cover is easily opened or removed for
service access and has a convenient fuse and relay
layout map integral to the inside surface of the cover
to ensure proper component identification.
The PDC cover, the PDC housing lower cover, the
PDC relay wedges, the PDC relay cassettes and the
PDC B(+) terminal stud module are available for ser-

vice replacement. The PDC main housing unit, the
fuse wedges and the bus bars cannot be repaired and
are only serviced as a unit with the dash wire har-
ness. If the PDC main housing unit, fuse wedges or
the bus bars are faulty or damaged, the dash wire
harness unit must be replaced.
OPERATION
All of the current from the battery and the gener-
ator output enters the PDC through two cables and a
single two-holed eyelet that is secured with nuts to
the two PDC B(+) terminal studs near the back of
the PDC housing. The molded plastic PDC cover is
unlatched and opened to access the battery and gen-
erator output connection B(+) terminal studs. Inter-
nal connection of all of the PDC circuits is
accomplished by an intricate combination of hard
wiring and bus bars. Refer to theWiring section of
this service manual for wiring diagrams.
