behind the clutch pedal. Additional fuses
are located in the engine compartment
(driver
’s side firewall) and also in the
sleeper (driver’s side of vehicle) under the
bunk storage compartment. Refer to the
fuse labels affixed at each fuse panel
location (generally under the fuse panel
cover) for information about the location
and amp ratings of each circuit.
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.
