when you use an obd 1 motor, b18c or b16a, in a obd II car, 96+ civic, with a skunk 2 conversion harness, what o2 wires do you use? do you wire up the primary plug in on the harness to fit for the primary o2 or do you use the secondary plug in to fit on the o2 senser?

 

Obd II or Obd I ECU
if the ECU is Obd I you don't need the second o2 wired at all it is only emissions. the primary must stay wired as that adjusts your fuel/air mixture.
If it is an Obd II ecu i think you will have more problem than just the o2 not sure about that though......
