WRONG. You are doing this WRONG!

FORGET the damn connector. Do this:

1) Grab the ratchet, with extension and socket.
2) Use the above to start taking the screw out.
3) As the bolt loosens, grasp the ratchet with one hand, and the connector (with CPS attached) with the other.
4) As the bolt comes loose, gently pull the CPS out, holding the ratchet so as so hold the bolt in the hole of the CPS.
5) As the entire assembly clears the heat shield and comes into view, gently set the rachet down. Then, grab teh bolt and set it down.
6) Disconnect connector from CPS.

THIS way, you don't struggle with that damn connector and you don't loose the screw!
