[QUOTE="mwolson, post: 13056942, member: 16006"] I just looked it up in the EVTM, and the PCM power is grounded at G104, which appears from the drawings to be up near the battery. The ground under the PCM is G201, which is the ground for signal returns and shielding. G201 is the better ground to use for the wideband to avoid ground offset when datalogging. EDIT: My recommendation here is wrong. See below. [/QUOTE]
