Neutral Safety Switch: Description and Operation

CIRCUIT OPERATION
When closed, the park/neutral position switch provides a ground path on circuit T41 for the coil side of the starter motor relay. Circuit T141 from the ignition switch provides battery voltage to the coil side of the relay.

Circuit T41 is double crimped at the coil side of the relay and connects to cavity A6 of the Powertrain Control Module (PCM). The park/neutral position switch provides an input to the PCM.
