specifying which motor would help too... ka, sr?

The stock harness has signal in the middle and non-polar ground and power on the outside pins. Just about every 3-pin heated narrowband o2 sensor is pinned like this.

Is this what you wanted, or do you need the signal wire to the ECU?

The power wire can go from any switched/fused power source, and ground to ground.

Anything left?

This is off the top of my head, but i believe it to be correct

Code:

Brown = Power               Red = Power                     White = Power
White = Signal              Black = Signal                  Black = Signal
Black = Ground              White = Ground                  White = Ground
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

can anybody verify this?^

The wiring is the same for black/redtop, correct?

My Apex'i Turbo Timer read the signal from the fatty O2 sensor just fine but when I swapped in the skinny, I get no reading.
