The sensor has three wires in total. x2 at a plug connector & x1 connected via a spade terminal [black].
None of the above seem to supply 12v with the ignition on or off!<ul><li><a href="http://www.unicomsystems.co.uk">Stock [ but not for long ] '92 UK Spec urS4</a></li></ul>

The single black wire is for the oxygen readings. The other two white wires run the sensors heater. For 02's with no heater there is only one wire, the "sensor" wire. If you are going to cut and splice a new universal sensor in all you need to do is connect black to black and "any of the two whites to any of the other two white wires".
