Air/fuel pressure gauge

Anyone know which wire from the PCM is the correct wire to tap for the air/fuel gauge? Autometer says to hook to the signal wire coming from the PCM for the O2 sensor. any help would be greatly appreciated

From what i have read, the wide band does indeed come with the weld in bung, but the narrow band just taps into the signal wire from the PCM. Any help in finding the right wire or pin, would be greatly appreciated.
