IOD FUSE (Continued)
when the vehicle is being prepared for delivery in
order to restore full electrical system operation. Once
the vehicle is prepared for delivery, the IOD function
of this fuse becomes transparent and the fuse that
has been assigned the IOD designation becomes only
another Fused B(+) circuit fuse.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed about thirty days. However, it must be
remembered that disconnecting the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than about thirty
days, the battery negative cable should be discon-
nected to eliminate normal IOD; and, the battery
should be tested and recharged at regular intervals
during the vehicle storage period to prevent the bat-
tery from becoming discharged or damaged.

REMOVAL

The Ignition-Off Draw (IOD) fuse is disconnected
from Junction Block fuse cavity # 34 when the vehi-
cle is shipped from the assembly plant. Dealer per-
sonnel must reconnect the IOD fuse when the vehicle
is being prepared for delivery in order to restore full
electrical system operation.
(1) Turn the ignition switch to the Off position.
(2) Remove the fuse access panel by unsnapping it
from the outboard end of the instrument panel.
(3) Grasp the outer tabs of the IOD fuse holder
unit in fuse cavity # 34 of the Junction Block
between the thumb and forefinger and pull the unit
firmly outward.
(4) Install the fuse access panel by snapping it
onto the outboard end of the instrument panel.

INSTALLATION

(1) Turn the ignition switch to the Off position.
(2) To install the IOD fuse, use a thumb to press
the IOD fuse holder unit in fuse cavity # 34 firmly
into the junction block.
(3) Install the fuse access panel by snapping it
onto the left outboard end of the instrument panel.
JUNCTION BLOCK
DESCRIPTION
An electrical Junction Block (JB) is located in the
left endcap of the instrument panel (Fig. 4). The JB
combines the functions previously provided by a sep-
arate fuseblock module and relay center. It also
serves to simplify and centralize numerous electrical
components, as well as to distribute electrical current
to many of the accessory systems in the vehicle. It
eliminates the need for numerous splice connections

and serves in place of a bulkhead connector between
many of the engine compartment, instrument panel,
and body wire harnesses.
The JB is positioned on a mounting bracket up and
under the left instrument panel. It is secured by four
screws. The JB is concealed behind the left instru-
ment panel endcap. The left instrument panel endcap
is a snap-fit fuse access cover that conceals the JB
fuses. A fuse puller and spare fuse holders are
located on the back of the endcap, as well as the fuse
layout to ensure proper fuse identification. The left
instrument panel endcap must be removed to access
components other than the fuses in the JB.

OPERATION

All of the current entering and leaving the JB does
so through wire harnesses, which are connected to
the JB through integral connector receptacles molded
into the JB housing. The JB houses blade-type fuses,
blade-type automatic resetting circuit breakers, full
International Standards Organization (ISO) relays,
and ISO micro-relays. Internal connection of all the
JB circuits is accomplished by an intricate network of
hard wiring and bus bars. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.
The fuses, circuit breakers, relays, and are avail-
able for service replacement. The JB unit cannot be
