Thank you very, very much for the excellent write up and picts on this procedure to uncouple the electrical connectors. I had never seen anything like these critters, and I succeeded in getting my knife blade underneath the thumb releasing bar (I thought it had to be raised) and prying up, breaking it. But, I can still slide the tiny red slider to the side, so partially released.
I would like to see your pictures put someplace where all newbees can see how to operate these tiny electrical locks.
God Bless you Shibbyutman!
