Random Junkyard Parts Identification

[ComancheMadness]

So I recently went to a junk yard and I saw a Comanche, so I started to dig for parts and I got some stuff that I have no clue what I got but it looked like it may come in handy in the long run, any clue on what I have, everything came out of a 91 comanche, thank y’all !

Bottom two are headlight warning buzzers.
