have you seen these pins? you might wanna change your response ff you have.Unplugging a wire harness is not going to "loosen it up and introduce the possibility of bending one again." The whole reason for the plugs is so that they can be un plugged and plugged back in. I deal with wire harnesses and plugs every single day and it is extremely rare that a pin bends. Usually if a pin gets bent it is because the person doing the work was in a hurry and being careless slamming things together.
and you contradicted yourself...You cant say its not going to loosen up if you dick with it, then say if a guys in a hurry he can dick it all up.
