2015 FORD F450 power steering

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:

Exceptions
There are several exceptions to the Normal
Schedule:
Axle Maintenance
Change the axle fluid anytime an axle is
submerged in water. Rear axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required or the assembly has been
submerged in water. During long periods
of trailer towing with outside temperatures
above 70°F (21°C) and at wide-open
throttle for long periods above 45 mph (72
km/h), change non-synthetic rear axle fluid
every 3000 miles (4800 kilometers) or
three months, whichever comes first. This
interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting
