I am having some problems with my O2 meter on my car.

First question is which connector and which pin should I hook my Dash Mounted O2 gauge to on the ECM.

Second My scan tool says the O2 sensors are just reading 444mV and not really moving. However when I flip over to the lean rich flag area, it is moving back and fourth and I go to the cross counts and I am getting cross counts of 4-12 but again the O2 mV is 444 and just stays there. (the OEM O2 sensors mV did move around, it is only since I put in the new ones that it stopped moving)

So what pin and should I just ignore the mV readings.
