2022 FORD F-150 auxiliary battery

WHAT ARE THE AUXILIARY
SWITCHES
The auxiliary switchboard on the overhead
console makes aftermarket customization
easier with six prewired switches
connected to the power distribution box.
Each circuit is individually fused for
connection of electrical accessories.
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.
• It is your responsibility to ensure that
any equipment you have fitted
complies with applicable local
legislation.
• An authorized dealer needs to install
mobile communication 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 dealer add any
electrical or electronic accessories or
components not produced by us to
your vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of the other electrical
systems in the vehicle. LOCATING THE AUXILIARY
SWITCHES
The auxiliary switchboard on the overhead
console makes aftermarket customization
easier with six prewired switches
connected to the power distribution box.
The circuits are individually fused for
connection of electrical accessories.
The switches have labels for AUX 1 through
AUX 6. They only operate when the ignition
is in the on position, whether the engine is
running or not. We recommend that you
leave the engine running to maintain
battery charge when using the switches
for an extended time or when using higher
current draw accessories. When you turn
on a switch, the indicator light on the
switch illuminates and the circuit provides
power to the device wired to that switch.
Note:
AUX switch 1 operates the off-road
lamps when your vehicle comes with this
option.

LOCATING THE AUXILIARY
SWITCH WIRING
There are three sets of blunt-cut and
sealed circuits. Two sets are under the
hood and behind the battery tray, and one
set is inside your vehicle at the passenger
footwell.
The powered set (A) is taped behind the
battery tray and has a red spot tape mark.
The second set (B) is also under the hood.
It is taped behind the battery tray and has
a white spot tape mark. This set routes to
the interior passenger footwell.
Remove the battery and battery tray to
access the underhood circuits. The interior set is taped on a wire harness
by the passenger side footwell. This set is
the other end of the circuits taped behind
the battery tray, with a white spot tape
mark.
Remove the fuse panel access door in the
kick panel to access the wires. If you do not
see them, you may need to pull them
down.
See Fuses (page 472). See your authorized
dealer for service.
Circuits from the under hood fuse box (A)
are powered. All other circuits (B-E) are
not connected at either end.
Additional information on fuse and relay
locations is available. See
Fuses (page
472). See your authorized dealer for service.
