im in the process of gutting my car. I want to remove everything that i dont need. These sensor im unsure about and ive checked the haynes manual and it doesnt say.

The first picture..i need to know what the black,grey and brass boxes do,,i think the black one is the feul pump rely but not sure




The second picture is the drivers side door almost underneath the 6x9 speaker. I want to know what the grey box is, the two black ones and the little cylinder thing.



Thanks alot
