I think it's pretty obvious once you look at them how they come off. They all have some sort of clamp that firmly attaches to the black cable sheath. Some of mine have a straight wire coming out of the end with a type of set-screw that grips it while others have a sort of loop on the end that simply hooks around a control level.

My heater panel was disassembled when I got my car, so thanks to Chris for the fiche pic, it will help.

I also noticed that I am missing several of those small clamps, I guess I'm going to have to rummage in the pic-n-pull to find replacements.

I have the micro-fiche printed out in a notebook and I also have one of these.
