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.
The switches are labeled 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 a switch
is turned on, the indicator light on the
switch illuminates and the circuit provides
power to the device wired to that switch.
Note:
AUX switch 1 is dedicated to the
off-road lamps when your vehicle is
equipped with this option. 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 is marked with a red spot
tape.
The second set (B) is also under the hood.
It is taped behind the battery tray and is
marked with a white spot tape. This set
routes to the interior passenger footwell.
Remove the battery and battery tray to
access the under hood 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 marked with a white spot
tape.
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 the Fuses chapter of your Owner
’s
Manual for information on fuse and relay
locations. See your authorized dealer for
service.
