Ford Repair: 1975 Ford F150 w/ 460 and Motorcraft 2 BBL, vacuum lines, mitchell repair

Question
I just purchased a 1975 Ford F150. It has a 460 and a Motorcraft 2 bbl in it. Several of the vacuum lines are detached and plugged. I have NO earthly idea where they go to. 1 of them comes out of the top of the intake on the left side ( if you look in while it is in the vehicle) and has a "T" valve connected to it. It has a lot of suction and seems important, but I have no idea where it is supposed to go to. Where might I find a vacuum routing diagram or find out where the vacuum lines go?


Answer
Call your local library. Ask them if they are like most libraries, and carry a complete selection of Mitchell repair manuals. It doesn't get any better than Mitchel's diagrams, instructions, etc. Simply make copies given the fact that it won't be the type book that the library checks out.
