  • After cat O2 sensor PCM pin#?

    Hello,

    I have problems trying to figure out what are the PCM pin#/wires that goes to the after-cat O2 sensor. My car is 2001 Firebird V6. I am planning to connect a DIY O2 sim directly in the PCM wiring harness under the hood.
    Also does anyone knows if it will throw a SES light when O2 sensor pre-heating circuit is disconnected? Thanks!
