Note: Spare fuse amperage may vary.
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. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.

AUXILIARY SWITCHES (IF
EQUIPPED)
For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
• When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
equipped with radio transmitters, for
example, two-way radios, telephones
and theft alarms. Any such equipment
installed in your vehicle should comply
with Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulations, and
should be installed by an authorized
dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford electrical or electronic
accessories or components to your
vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of other electrical
systems in the vehicle. The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches operate when the vehicle is
running or from battery power, depending
on the switchable PDB fuse locations #82
and #83. 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.
When switched on, the auxiliary switches
provide 20 amps or 40 amps of electrical
battery power for a variety of personal or
commercial uses.
The switches include the fuse and relay kit.
This kit contains the required fuses and
relays that an authorized technician needs
to install into the power distribution box,
located under the hood. Refer to the
instruction sketch included in the kit.
Contact an authorized dealer for service.
Each switch includes a power lead (a
blunt-cut and sealed wire) located in the
underhood cowl shield above the engine
block powertrain control module.
The power leads are coded as follows:
