UPFITTER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with
the Upfitter option package which
will provide four switches, mounted
in the center of the instrument
panel, labeled AUX 1, AUX 2, AUX 3
and AUX 4. These switches will only
operate while the ignition is in the 4
(ON) position, whether the engine
is running or not. It is, however, 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 4 [ON] position.)
When switched on by the operator they provide 10 amps or 30 amps of
electrical battery power for a variety of personal or commercial uses.
If your vehicle is equipped with this
option, there will also be a relay box
with a fuse located inside the glove
box.

The relays and fuse in the glove box are coded as shown in the
accompanying illustration.
There will also be one power lead
for each switch found as a blunt-cut
and sealed wire located behind the
passenger compartment fuse panel.
They are coded as follows:
Switch Circuit number Wire color Fuse
AUX 1 1936 Orange with
Light Green
Trace 30A
AUX 2 1933 Orange 30A
AUX 3 1934 Orange with
Yellow Trace 10A
AUX 4 1935 Orange with
Light Blue Trace 10A
More detailed information about the Upfitter switches can be found in
the Electrical Wiring section of the Ford Truck Body Builders Layout
Book , found at www.fleet.ford.com/truckbbas.

Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions such as
slower speeds and increased stopping distance should be taken when
driving a heavily loaded vehicle.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the 4 (ON) position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the 4 (ON) position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to 2 (LOCK), then remove
the key.
2. Insert the key and turn it to 3 (OFF). Apply the brake pedal and
shift to N (Neutral) .
When the key is in the ignition and in the OFF position, the
automatic transmission shift lever can be moved from the P
(Park) position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to Fuses and relays in the Roadside
Emergencies chapter.

This switch is located in the front
passenger’s footwell, behind the kick
panel access cover.
To reset the switch:
1. Turn the ignition off.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition on.
5. Wait a few seconds and return
the key to off.
6. Make another check for leaks.
FUSES AND RELAYS
Fuses
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.
Note: 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. 15
