    That is your map sensor which usually is mounted next to the TBI unit on the passenger side.

    80-87 E4ME ESC controlled cars and trucks have a MAP sensor, some of them called another name though like MAS or something else, id have to look it up again to see.
    looks identical to a MAP sensor though

    that in your pic is probably the tranny lockup vaccum electrical switch though, sometimes theres another one like it on other side of firewall about there too,
    started for '80-up fuel mileage crappy axle highway ratio/emisisons days along with ESC system junk

    kinda hard to tell what all is in your pic, kinda far away pic to see the smaller stuff there on firewall
