change out 67 dart remote mirror glass

so what's the catch to hooking up the remote cable that has like these little like probe fingers that are the movements when u move the interior post stem that's where I don't get how that hooks up to the back side of a mirror .cause I think a guy big in mopar parts here locale got that for me .he's not even sure how that reconnects to the back side of the mirror .
the same way they hook to the adjuster on the opposite end. you can pull them apart , I like to mark a couple of them first. I have a remote mirror in pretty darn good shape, that I`m not going to use. I forgot to drill the extra hole for it before I painted my car.
