WARNING
To prevent personal injury or death when
performing maintenance and repairs to any
turbocharged engine with engine air inlet piping
disconnected, a turbocharger compressor air
inlet protective shield should be installed over
the turbocharger air inlet.

wire gauge to meet the fuse and circuit breaker
current rating. Do not increase size of fuse or
circuit breaker or change type of breaker supplied
with your truck. To do so could cause wiring to
overheat and possibly burn, resulting in a fire
which could cause property damage, personal
injury, or death.
