vacuum schematics arent always same just because same engine and model and year.
different emissions levels and packages plus if built in 48 states or in cali or in canada all have different vacuum schematics
i would go to a junkyard and try to locate another vna your year with same three letter emissions digit code on the sticker,.
or in the SPID label in glovebox in the engine cover
the vacuum lines on these are pretyt basic though
not much to them.
egr vacuum solenoid
heater a/c vacuum line
most everything connects to or originates from an intake manifold vacuum source
i might have the sticker on the rad support of the 92 i just stripped, ill check and see
