All will be schematics like found on rad support in engine bay.
You basically will have 2 larger vacuum hoses, one for power brakes and one for PCV Valve.
Smaller hoses go to
EVAP Solenoid(usually drivers side engine bay, will have 2 vacuum hoses, in/out, and 2 wire electrical connector)
Fuel Pressure Regulator(behind alternator, has Fuel line, return line, attached to it)
Vacuum reservoir(on top of fan/blower box on most 1994's)
(FPR and reservoir can share one hose, and there will be a "T" on it splitting it to the two devices)
Vacuum reservoir will have another black line(looks like a wire) coming out and running thru firewall, and a Grey line coming out of firewall(maybe) right next to it, grey hose runs to heater hose valve "IF" so equipped
This Black line is for running the Vents inside the cab, i.e. floor, panel, defrost selector for air flow
Optional hoses
EGR solenoid(calif. only, or if so equipped)
Cruise control, if so equipped
