UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches will only operate
while the ignition is in the on
position, whether the engine is
running or not. However, it is
recommended that the engine
remain running to maintain battery charge when using the upfitter
switches for extended duration or higher current draws. (This is even
more important for vehicles with diesel engines since the glow plugs are
also draining battery power when the ignition key is in the on position.)
When switched on, they provide 8 amps, 12 amps or 20 amps of
electrical battery power for a variety of personal or commercial uses.
There will also be a relay box located on the driver side end of the
instrument panel. See your authorized dealer for service.

The relays are coded as shown.
There will also be one power lead
for each switch found as a blunt-cut
and sealed wire located below the
instrument panel and to the left of
the steering column.
They are coded as follows:
