The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches operate only when you switch the
ignition on, 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.
When switched on, the auxiliary switches
provide 10 amps, 15 amps or 30 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: Fuse
