Why?
11&up run in closed loop all the time. The PCM will deliver the commanded AFR in the tune.
I would not have added an AFR guage had I known this before my build.

I would not attach anything to the OEM sensor, you may end up causing issues. If you are dead set on a WB, add a standalone sensor/gauge.
