From what I've read the oxygen sensor replaces the CO pot, but don't quote me. I imagine the oxygen sensor goes to a different pin.
To retrofit a CO pot you will need:
- A wire from pin 8 of the ECU
- An earth reference (it shares this with TPS and MAP Sensor)
- A sensor live (again, take the one shared with TPS and MAP Sensor)
