93 ford ranger vacuum problem
I have a 93 ford ranger with a 4.0 motor. I am wondering if anyone might know where I could find a schmatic of the vacuum system, the one under the hood just isn't clear enough,,,ok here's the problem I probably should have started there,,,my daughter brings the truck home and says something is wrong with it,,,first off letting daughter drive said truck was a mistake,,so I proceed out to find the truck missing and check under the hood to find a vacuum line disconnected, but I can not find the other end anywhere, for all the 4.0 guys out there it's one of the small lines coming off of the back, there are two, one going to the ac controls and the other looks like it might be going around the same way and hooking up to something by the throttle body, then there's the third one that is just going out into limbo, it is connected to a small piece of hardened plastic and going no where. I hope all this rambling is making some sort of sense, any and all help is deeply appreciated,,thanks in advance.

1 small line does go to the heater/A-C controls, 1 small line goes to the fuel pressure regulator ( passenger side of engine close to front ) 1 Larger line goes to the trans, ( if auto ) and another larger line goes to the cruise control if so equipped.
