FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. The power distribution box is located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 244).

CHANGING A FUSE
Fuses WARNING
Always replace a fuse with one that
has the specified amperage rating.
Using a fuse with a higher amperage
rating can cause severe wire damage and
could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. A
break in the fuse wire will indicate a blown
fuse. Check the appropriate fuses before
replacing any electrical components.

The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches operate only while the ignition is
in the on position, whether the engine is
running or not. Ford recommends, however,
that the engine remain running to maintain
battery charge when using the auxiliary
switches for extended periods of time or
higher current draws.
Note:
When your vehicle has a diesel
engine, use the auxiliary switches only while
the engine is running. The glow plugs also
drain battery power when the ignition key is
in the on position. Using the auxiliary
switches, even for limited amounts of time,
can cause your battery to drain quickly and
prevent your vehicle from restarting.
When switched on, the auxiliary switches
provide 8 amps, 12 amps or 20 amps of
electrical battery power for a variety of
personal or commercial uses.
The relay box for the auxiliary switches is
on the end of the left side of the instrument
panel. See your authorized dealer for
service.
The relays are coded as shown: Each switch includes a power lead, a
blunt-cut and sealed wire located below
the instrument panel and to the left of the
steering column.
The power leads are coded as shown:
