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 proper-
ty damage, personal injury, or death.
WARNING
Never install a circuit breaker/poly-
switch
in a location indicated for “fuse
only.” Using a polyswitch (circuit
breaker) in a fuse-only circuit may
cause the circuit to overheat when a
short exists, which could lead to equip-
ment damage and/or personal injury.
NOTE
Polyswitches/circuit breakers are al-
lowed
in certain locations as indicated
by the label on the fuse box. In these
applications, a fuse may be used in-
stead of a circuit breaker
.
CAUTION
Follow all manufacturers' circuit pro-
tection
recommendations for the com-
ponents and wires being added. Fail-
ure to comply may result in equipment
damage.
NOTE
If you are unfamiliar with proper elec-
trical
repair practices and procedures,
see your authorized dealer for assis-
tance.
Vehicle CAN Bus
Y
our vehicle is equipped with a CAN bus
electrical system. Because of how the
electrical system is designed it is important
that any accessories added after the
vehicle is built are installed only on the K-
CAN or the S-CAN. These dedicated CANs
are provided on the driver's side of the cab,
near to the interior fuse panel. Access to
the K-CAN and S-CANs is provided by two
RP1226 connectors. DO NOT tap into,
connect to, tamper with, or splice into any
CAN network other than the K-CAN or the
S-CAN. Connecting to a unapproved CAN
network may trigger CAN fault codes.
CAUTION
Connecting to an unapproved CAN
network
may trigger CAN fault codes.
The manufacturer will not warrant fail-
ures or damage caused to CAN net-
work components when the failure or
damage is a result of improper con-
nections to the CAN network.
