Altering the Electrical System
Refer to a wiring diagram for your chassis
before adding electrical options to ensure
proper electrical system performance.
WARNING!
Do not replace a fuse with a fuse of a higher
rating. Doing so may damage the electrical
system and cause a fire. Failure to comply
may result in death, personal injury, equip-
ment or property damage.
WARNING!
Never install a circuit breaker in a circuit that
is designated as "fuse only" circuit(s). Fuse
only circuits are marked with an * on the re-
verse side of the Power Distribution Box
cover. Using a circuit breaker in those fuse
only circuits may cause the circuit to over-
heat when a short exists which could lead to
equipment damage and/or personal injury.
CAUTION
Follow all manufacturers' circuit protection
recommendations for the components and
wires being added. Failure to comply may
result in equipment damage.
NOTE
If you are unfamiliar with proper electrical
repair practices and procedures, see your
authorized dealer for assistance.
Batteries
Information on maintaining your vehicle's
batteries.
Regular attention to the charging system
will help prolong the service life of the
batteries.
WARNING!
Batteries contain acid that can burn and
gasses that can explode. Ignoring safety
procedures may result in death, personal in-
jury, equipment or property damage.
WARNING!
Never remove or tamper with battery caps.
Ignoring this could allow battery acid to con-
tact eyes, skin, fabrics, or painted surfaces.
Failure to comply may result in death, per-
sonal injury, equipment or property damage.
WARNING!
Replace only with AGM (Group 31) batter-
ies. Use of other batteries could result in
acid leaks causing personal injury in the
event of a vehicle accident. Failure to com-
ply may result in death, personal injury,
equipment or property damage.
WARNING!
Battery cables and air/electrical harnesses
are mounted to the bottom of the floor. Do
not drill or screw into floor pan without first
checking the location of the cables, har-
nesses or any other component that might
be damaged. Damaging any component
could result in electrical shock which could
cause personal injury and/or loss of a critical
truck system. Failure to comply may result
in death, personal injury, equipment or prop-
erty damage.
