A/T Models

Power is supplied at all times:
^ through 3O A fusible link (letter [i] located in the fusible link and fuse box)
^ to ignition switch terminal [1].

For models with theft warning system (and with ASCD)
Power is supplied:
^ through 1O A fuse (No. [21] located in the fuse block [HEC])
^ to theft warning relay terminal [1]
^ to theft warning relay terminal [3]
^ through theft warning relay terminal [4]
^ to inhibitor relay terminal [1].
If the theft warning system is triggered, terminal [2] of the theft warning relay is grounded and power to the inhibitor relay is interrupted.
When the theft warning system is not triggered and the ignition switch is in the START position, power is supplied:
^ from ignition switch terminal [5]
^ to inhibitor relay terminal [6].
With the selector lever in the "P" or "N" position, ground is supplied:
^ from inhibitor switch terminal [1]
^ to inhibitor relay terminal [2]
^ through inhibitor switch terminal [2]
^ to body grounds E13 and E25.
The 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.

For models without theft warning system
Power is supplied at all times:
^ through 3O A fusible link (letter [i] located in the fusible link and fuse box)
^ to ignition switch terminal [1].
Power is supplied:
^ through 1O A fuse (No. [21],located in the fuse block [HEC])
^ to inhibitor relay terminal [1].
With the ignition switch in the START position, power is supplied:
^ from ignition switch terminal [5]
^ to inhibitor relay terminal [6] (models with ASCD)
^ to inhibitor relay terminal [3] (models without ASCD).
With the selector lever in the "P" or "N" position, ground is supplied:
^ from inhibitor switch terminal [1]
^ to inhibitor relay terminal [2]
^ through inhibitor switch terminal [2]
^ to body grounds E13 and E25.
The inhibitor relay is energized and power is supplied:
^ from inhibitor relay terminal [7] (models with ASCD)
^ from inhibitor relay terminal [5] (models without ASCD)
^ 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.
