Need help removing the CPS. There is a plate that partially covers the base of the CPS. From looking up top, I cannot see the bolt that anchors the CPS.

1. Should I remove this plate first?
2. Also should I disconnect the CPS before removing it?
3. To get the wire off the CPS, should I be able to pull it off or does in lock in place and I have to press the tabs to get it off?
