oxygen sensor wiring diagram s13

[SoguRacing]

I need an oxygen sensor wiring diagram.
not sure which is ground, signal, and heater circuit. just a post would help thanks.

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

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

it would be a redtop s13 sr20det. my bad

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.
