The plug half came off of the sensor side of the oxygen sensor connector (don't ask me how...) and the wire colors are not the same on both sides.  The chassis side wire colors match the wiring diagram:  BW, YR, W.  But the wires on the sensor itself are Red, Black and White.  Since they are no longer in the plug I do not know which ones to match up.  Help please!

 

Thanks,

Mike V.

Get out the ohmmeter.

Two of the wires will show continuity to each other. Those are for the heater circuit. Doesn't matter which way they to back, those wires go in pins 1&2.

The 3rd wire may show continuity to ground, but it may not. That's the signal wire, and goes in pin 3.

 

If you're holding the connector with the lock tab on top, 1&2 are on top, 3 is the bottom pin.
