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.
E163431
The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches operate when the ignition is on
or from battery power, depending on the
switchable power distribution box fuse
locations #82 and #83. We recommend,
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 20 amps or 40 amps of electrical
battery power for a variety of personal or
commercial uses.
The relays for the auxiliary switches are in
the power distribution box under the hood
by the right-hand fender. See your
authorized dealer for service.
Each switch includes a power lead, a
blunt-cut and sealed wire below the
instrument panel and to the left of the
steering column in the driver footwell area.
The power leads are coded as shown:
