Checking Power Cables
Every cable and wiring harness on this truck is manufac-
tured to an exact specification. A shorter cable or harness
will not fit. If either a harness or cable is routed improp-
erly, it will not fit. Subsequently, electrical shorts and
damaged components may result if the replacement part is
the wrong one, or if it is routed incorrectly.
Torquing Fasteners
Improperly torqued fasteners can cause damage
Use an appropriate wrench and tighten all fasteners to the
torque specified in the following inspection procedures.
