How many O2 sensors?

[Bruce]

I have 2 bungs in my exhaust.
One for the WB, and one for the oem one
The nordskoddoggie unit is a guesssometer, at best and that's with the oem
one, and doesn't work with the WB

> I'm going to get o2 sensor bungs welded into my exhaust on my '85 suburban
in anticipation of my TPI upgrade, and to help with tuning the (ugh!)
carburetor that's there now.  I know the ECM is going to need an input from
the o2 sensor, but I want to run a gauge or indicator in the cab as well.
Can the two share the same o2 sensor, or do I need separate ones for ecm and
indicator?  Also, could a gauge, like the Nordskog performance analog model
70140 (http://nordskogperformance.com/d70140.html) be used with the WBO2
sensor?
