2021 FORD E-450 auxiliary battery location

12 Volt DC Power Point
WARNING: Do not plug optional
electrical accessories into the cigar
lighter socket. Incorrect use of the cigar
lighter can cause damage not covered
by the vehicle warranty, and can result
in fire or serious injury.
Note: When you switch the ignition on, you
can use the socket to power 12 volt
appliances with a maximum current rating
of 15 amps.
If the power supply does not work after you
switch the ignition off, switch the ignition
on.
Note: Do not hang any accessory from the
accessory plug.
Note: Do not use the power point over the
vehicle capacity of 12 volt DC 180 watts or
a fuse may blow.
Note: Always keep the power point caps
closed when not in use.
Do not insert objects other than an
accessory plug into the power point. This
damages the power point and may blow
the fuse.
Run the vehicle for full capacity use of the
power point.
To prevent the battery from running out of
charge:
• Do not use the power point longer than
necessary when the vehicle is not
running.
• Do not leave devices plugged in
overnight or when you park your vehicle
for extended periods. Locations
Power points may be in the following
locations:
•
On the instrument panel.
• Inside the glove box.
• Behind the driver's seat, upper trim
panel.
110 Volt AC Power Point
(If Equipped) WARNING:
Do not keep electrical
devices plugged in the power point
whenever the device is not in use. Do not
use any extension cord with the 110 volt
AC power point, since it will defeat the
safety protection design. Doing so may
cause the power point to overload due
to powering multiple devices that can
reach beyond the 150 watt load limit and
could result in fire or serious injury.
Note: The power point turns off when you
switch the ignition off, or when the battery
voltage drops below 11 volts.
You can use the power point for electric
devices that require up to 150 watts. It is
on the rear of the center console. To gain access to the outlet contacts,
press the plug against the outlet and rotate
clockwise.

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:
