That's where the lead from the oxy sensor connects.  Since it's not
connected, the sensor is having no effect at the moment -- the other two
leads on the sensor are just a heater to kick-start it.

Using a digital meter you should see close to 500 mv from that lead to
ground when the ignition is on, cold engine.  If you see near zero instead,
there's quite likely a short from the inner conductor to the shield which
is grounded.  That would make the ECU go to full rich as soon as Temp II
indicated warmup.
