A/T Models

Power is supplied at all times:
^ through 30 A fusible link (letter (i), located in the fuse and fusible link box)
^ to ignition switch terminal (1).

Models without ASCD
With the ignition switch in the ON or START position, power is supplied:
^ through 10 A fuse [No. (25), located in the fuse block (J/B)]
^ to inhibitor relay terminal (1) (models without theft warning system)
^ to theft warning relay terminal (3) (models with theft warning system).
Also, with the ignition switch in the START position, power is supplied:
^ from ignition switch terminal (5)
^ to inhibitor relay terminal (3).
If the theft warning system is not triggered, power is supplied:
^ through theft warning relay terminal (4)
^ to inhibitor relay terminal (1) (models with theft warning system).
With the selector lever in the P or N position, ground is supplied:
^ to inhibitor relay terminal (2) through the inhibitor switch.
Then inhibitor relay is energized and power is supplied:
^ from inhibitor relay terminal (5)
^ to terminal (1) of the starter motor windings.

Models with ASCD
With the ignition switch in the ON or START position, power is supplied:
^ through 10 A fuse [No. (25) located in the fuse block (J/B)]
^ to inhibitor relay terminal (1) (models without theft warning system)
^ to theft warning relay terminal (3) (models with theft warning system).
Also, with the ignition switch in the START position, power is supplied:
^ from ignition switch terminal (5)
^ to inhibitor relay terminal (6).
If the theft warning system is not triggered, power is supplied:
through theft warning relay terminal (4)
^ to inhibitor relay terminal (1) (models with theft warning system).
With the selector lever in the P or N position, ground is supplied:
^ to inhibitor relay terminal (2) through the inhibitor switch.
Then inhibitor relay is energized and power is supplied:
^ from inhibitor relay terminal (7)
^ to terminal (1) of the starter motor windings.
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.

THEFT WARNING SYSTEM
The theft warning system will interrupt power supply to clutch interlock relay (M/T models) or inhibitor relay (A/T models) if the system is triggered. The starter motor will then not crank, and the engine will not start.
