If the ecu doesn't support a 4-wire o2 sensor then it can't really be done that way. If you changed the ecu, then you can more than likely find a diagram for the ecu pinouts or locations for the ground, 12v+, and heater wire in one of the manuals posted above...i believe the one for 92+ civic should have that info, just download it and search through it.
