Air/Fuel ratio gauge installation?

[2nr4lif]

I'm trying to install my autometer air/fuel ratio gauge in my '95 non-turbo. There are four wires coming off of the heated O2 sensor ( 2 white ones, 1 black, and 1 grey). Which of these wires do i tap the air/fuel gauge signal wire in to?

tap into the white wire with black stripe. that's the wire you want to tap into with the purple wire from your autometer gauge.
later
