There is usually a vacuum hose diagram decal under the hood.

On radiator support or under hood ,on all vehicles, on

Try the public library. We don't have diagrams that go back this far.

This should give you everything you need...

THat goes to your map sensor. If you look very closely under your hood there will be a vac line diagram there

Does your turn signals, high headlight beam work? Also, does the AC function through the dash vents and not the defrost vents?

My cruise control quit and I found it was the vacuum lines running to the servo.
