I have been searching for a while and i just want to know which wire is which. My 02 sensor has 4 wires, i know the 2 white ones are for the heater but which is the signal? the grey or black? I have always known of black meaning ground but autozone tells me that the black is the signal.
I believe contestant #2 is attempting to sell something with humor to smooth over.
To contestant #1, with no explaination as to why you will probably not receive many answers to the Q! But get out a pair of wire cutters and be ready, just in case.
