Thanks, Bill.  Been looking for a diagram for using one of the wide-band
sensor.  One nice thing about the wide-band O2 sensor is that the response
curve is much less radical than the typical O2 sensor which means you can
get a better feel for what the indications are telling you.  The voltage
curve around 14.7 A/F ratio of typical O2 sensor is so steep that just a
little bit off makes a bit difference in the indication.

Only down side, is last time I checked the wide band O2 sensor were fairly
expensive compared to the older ones.
