does anyone know where i can dowload the engine schematics for the the 1990 gmc sl sierra?

my girlfriend has an old gmc siearra truck and i would like to get it running for her, but i need to know where everything leads to so i need a diagram of the engine. can anyone out there get me a link to a site where i can get the diagram from?
I would say one of your best bets would be to go to a bookstore and get a Chilton's book :) I don't think you can find the engine schematics online for free (maybe, but I've never come across them.) You could also go to a dealership and see if they would
