Hi everyone,

I got an issue,

on my motor b18cr,

Wiring= Main Colour/Striped Colour

Black/White
Green/Black

White
Yellow/Black

I got a universal sensor . with 2 Black Wires, 1 Blue & 1 White.

Anybody know the correct wiring to each other?

Thank you.

measure the resistance of the black wires, should be 20 to 40 ohms, this would be the PO2H
white would possibly be the PO2S and blue PO2S ground
