    Default O2 Sensor wires

    Can someone tell me what color corresponds to which wire on the rear o2 sensor. I have a 99. I cant find my shop manual. Thanks

    The diagram I have shows:

    Red: sensor output to computer (shielded wire)
    Blk/Red: sensor feed from computer
    Red/Yel: Heater power from computer
    Blk/Wht: (???) wire goes off the page and haven't figured out where to yet... looks like ground...

    PM me your email addy & I'll send you the diagrams I have.
