How To: 1 wire O2 > 4 wire O2
O2 Sensor --> 1 wire to 4 wire
Wires on 4 wire O2:
WHITE: Signal Wire
GREEN: Signal Ground
2 BLACK: Both black wires are the heater circuit wires.
**Using a P28 ECU**
Run O2 Sensor signal (white) To D14
Run O2 Sensor signal Ground (green) to D22 (or any good Ground)
Run O2 Sensor Heater Circuit Control (black) to A6
Run the other black heater circuit power wire to (A25) or any good switched +12VDC source.
