I got hold of a VR3 2 pin lead and beeped it out.
Here are my findings.
Aligned with red spot on outer shell is Pin 1.
Top pin = 1 = Negative connector to the O2 cell (negative)
Bottom pin = 2 = Positive connector to the O2cell (positive)
VR3 P port connector Pin1 connected to blue lead of Molex = negative connector of O2 cell, Pin 2 connected to white lead of Molex = positive connector of O2 cell.
