M/T MODELS
Power is supplied at all times
lthrough 30A fusible link (letter J, located in the fuse and fusible link box)
lto ignition switch terminal 1.
With the ignition switch in the ON or START position, power is supplied
lfrom ignition switch terminal 5
lto starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
A/T MODELS
Power is supplied at all times
lthrough 30A fusible link (letter J, located in the fuse and fusible link box)
lto ignition switch terminal 1.
With the ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No,13 located in the fuse block (J/B)]
lto park/neutral position relay terminal 1.
With the selector lever in the P or N position, ground is supplied
lto park/neutral position relay terminal 2
