Hi, the autozone site has free diagrams. You have to register your vehicle, it's free. Then click on repair info. I believe the vav diagrams is under the emissions link. Wiring diagrams under chassis link.

Since you only require the trans vacuum, forget about all others and get the vacuum direct from the source, which is the carburettor. One vacuum line would do.
