Help - VR3 2 port connector

[jknights]

Please can somebody tell me the polarity of the VR3 pins.
What connector is + and - for the VR3 to O2 lead.

I have the VR3 with 2 pin out.
I only want to make up a O2 sensor lead.

The pin aligned with the red spot (of the plug) is ? positive/negative ?


Thanks in anticipation.

As a FYI to others
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.
