Is there full vacuum line schematics for 93 Ford Aerostar?

What ever search engine you use, type in www.autozone.com/repair_info.

Now you see a page of search results, on the one showing AutoZone.com | Repair Info click on it. Now on the left side of the Auto Zone screen, find Vehicle Repair Guides and click on it. Now select vehicle year and click on it. Click on Ford. Click on Aerostar 2 WD or 4 WD. Click on 3.0 or 4.0. Now it shows Repair Guide so click on Driveability & Emissions Controls now on the right of the page there is a list of options to pick, choose Vacuum Diagrams then find your year and motor. I find the Autozone web site helpful at times
