Where can I get a diagramed book on 1981 Caddy emission gismos and their proper vacuum controls hook-ups?

'81 Cad w/368cu" had used motor installed at a lic. garage. Has been discovered that elec-controled vacuum ports are not hooked up. Two vacuum lines go nowhere. Smog pump was not hooked up to the air management valve and same has ports for (?). Mechanic failed to even install the PCV valve. Can not go back to shop as the mechanic sold it. Have received 4 of 6 books ordered on emissions that helped me fix the PCV-yet, I don't know if it's supply vacuum is direct or whether it is supposed to come through a thermal control unit. Have hooked up the smog pump to the air management valve but there are vacuum ports going nowhere. All diagrams available in auto service manuals appear to be designed for a trained mechanical technician as descriptive terms are abreviated and there are no identifying pictures of "whar" goes to "what." Could use something like "EMISSIONS %26amp; DIAGRAMS W/PICTURES of PORTED ELECTRONIC CONTROLS" as would be applied to a 1981 General Motors 6.0L V8(6-4). HELP !|||I would try getting a GM restoration packet. Call 800-222-1020 and give them your VIN. If that doesn't work, check your Haynes/Chilton manual.|||u can get it fron online book shop offering the books . acn get it fron books.com
