I've noticed lately that a lot of people have been asking for vacuum diagrams and wiring diagrams for their 3rd gens lately. These diagrams are available online at Autozone.com. They basically have the whole Haynes manuals (Chilton's manuals are similar) online free of charge. It covers pretty much all of the basic and general repair procedures. The Haynes manuals do leave a lot to be desired in certain areas, but they are great for the average do-it-yourselfer.
I would highly recommend a factory service manual (available at www.helminc.com) if you need a more detailed repair guide.
