Splice S111 is the splice to the Sensor Ground network. This wire will have around .016-.020 volts on it when the ignition switch is to RUN (engine not running), and zero volts on it when the switch is OFF/LOCK. The Gray/Yellow tracer wire may have around .072 volts on it with the ignition switch to OFF/LOCK, and some higher voltage on it when the switch is to RUN (engine running)."

Circuits check per the above values. Looks like I need to source a connector.
