Adding air/fuel gauge

["ambradley@frontiernet.net" <ambradley@frontiernet.net>]

Actually, more about adding an O2 sensor.  How hard is it to add an O2
sensor to an existing non-catalytic, non smog pumped car?  Can I take
my Roadster to a muffler shop and say "add an O2 sensor to the
downpipe"?  Does the O2 sensor itself need power or do I just run a
wire from the O2 to the air/fuel gauge and then run power to the gauge?

Thanks,
