    Default Silverado 2003 + PCM DBW Ground ?

    Can someone tell me if the grounds on the Blue Connector Pin's#24, 27, 64 & 67 are needed for the PCM internally or are they there for the O2 sensor's? I'm using the normal ground's on Pin's 1 & 40 on Blue connector & Pin's 1 & 40 on green connector. I'm going to be running OL-MAF or OL-SD so O2's will not be needed(OFF ROAD USE ONLY...) It just seems like to many grounds...IDK maybe I'm wrong and the PCM needs them.
