I don't know but i can give u this.
This is a maintenance manual for determine it is working good.
wideband O2 sensor and Secondary O2 sensor is different.
But i guess 1 is cathode 3 is anode ,the 2 and 4 just for feedback , it just my guess .
So i think u can made 2 resistance in 2 and 4 to "fool" the ecu and power for your new O2 use 1 and 3.
