the first one came off of a bag most likely. I had the same thing, it's the sticker that goes on the bag that holds the weird torx screw wrench (or whatever they call it) for all of those weird screws like tron has and others.
The yellow wire is just a ground strap and could connect any 2 points of metal.
The big red 'Do Not Discard' came off a plastic bag that had the leg levelers (if the bab had them) and security torx wrench that was likely placed in the coin box. It doesn't go on the cabinet.
