CHANGING A FUSE
Fuses WARNING: 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. 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.

AUXILIARY SWITCHES
The auxiliary switchboard on the center
console makes aftermarket customization
easier, with four prewired switches
attached to the power distribution box for
electrical accessories. When using the auxiliary switches for an
extended period of time, we recommend
that the engine is running to prevent the
battery from running out of charge.
A fuse and relay kit is included with this
option. The kit contains fuses and relays
for the pre-fusebox, located under the
driver
’s seat. Refer to the instructions
included with the kit. See an authorized
dealer for service.
There is one power lead connector for each
switch. These can be found at either the
43-way connector for the AUX 1 and AUX
2 switches or the 6-way connector for the
AUX 3 and AUX 4 switches. Both
connectors are behind the passenger side
cup holder.
The relays are coded as follows: Fuse Rating

please contact the Truck Body Builders
Advisory Service. See Special Notices
(page 16).
