greetings and welcome. nice summer project !
the map fits on the fire wall, and vacuum to its own special nipple. at rear of intake.
seen here, the twin hose , prevents freeze ups (ice ups) when cold and blocking vacuum to map. btw.

the early engine has odd vacuum hoses. (frames 41 to 45 above)
the dash pot, VSV valve? smashed is easy to do ,its very fragile.
no egr, so do dont use it. (it might throw code 51 DTC, cross fingers it dont go to limphome mode, like same california, ECU do)
the dash pot missing means starting engine can be harder, missing all that fresh air.... may flood starting.
one guy i know adds foot throttle about 5% to start car, due to that DP missing.
if the vsv is missing the DP is active full time. and engine screams 3ooo or more at hot idle. so then he took the actual DP off TB. and no more DP.
the ECU assumes it works, and sets fuel ratio based on it working to start cold.
with the EGR main missing the VSV is useless. sure.
