you were right, there are 2 of them (yellow). I was trying to pull the lower (and bigger one). No way that one is coming out. There is one hiding further up on the board behind a whole cluster of wires. looks like it has the easy clip you described. As I look at it, it has 3 wires running to the connection.

Would someone like to clarify if that's the one I want before I disconnect it?

thanks.
