Which O2 wire is signal? S70 1998

posted by  someone claiming to be Gavin Lim on  Thu Apr 12 16:58 CST 2001 [RELATED]

I'm trying to install an A/F meter and saw 4 wires from the O2 sensor (front only) namely black, grey and 2 whites. Which is the signal wire that I need to tap? I believe two wires are for the heater rite?
