Using 4 wire lambda sensor

[OrMar]

I would like to replace lambda sensor on my AAN and have 2 brand new 4 wire probes ready.
Could I use one of these instead of buying new one ?
It has black, grey and 2 white wires, and I can't find any thread with instructions how to wire it.


Thanks,
Mario

2 white is heat. think black will be signal and grey ground.

OK, but how to wire 2 whites ?
One to original white from harness, and another to ground ?

the probe has a heat ciruit in there. like a lightbulb. the original probe should have the same. non heate3d probes are very rare now.
