I found an old thread but it's closed, so I can't write my question there.
I have an 3-wire heated O2 and I'm not sure which wire is the signal wire to the ECM ...
I found a schematic at sethirdgen.org, but my sensor has different colors what is shown in the second pic.
Does anybody know which wire I have to connect to the ECM?

Hi Eike,
Do you have the stock 1 wire sensor installed? Yes? It has one violet/purple single cable. This is the ECM wire.
Ohm it out to try and identify the heater. It should be a low value and polarity would not change it.
post your measurements here I'm sure the forum can solve it
Yes, I know that ... but I don't know which of the three wires (grey/black/yellow) goes to the ECM.
Probably I don't understand... But it seems clear that is the "C" one in the wiring diagram NON the "A" NOT the "B".
In your pic it is the gray wire.

Good answer, i didn't even see the "ABC" on the pic of connector the first time around
