1. Engine stop switch button
2. STOP position
3. RUN position
When the engine stop switch is set to "RUN", it
completes a circuit between the ignition switch
and the ECM. This circuit provides the 12 Vdc
power used to initialize the ECM.
If the engine is running and the engine stop switch
is set to "OFF", it opens the 12 Vdc circuit to pin
A4 of the ECM. Ignition will cease immediately,
the engine will shut down, but the ECM will main-
tain power on the vehicle for 30 seconds.
If the engine stop switch is left in the "STOP" po-
sition when the ignition switch is turned to "ON",
the ECM will not be initialized, the headlights and
tail light will not turn "ON".
