There are several forums for owners of particular vehicle types, and wiring diagrams can often be found on them. Agreed, enthusiasts/owners forums are great for that. Or Google your car, put in "1998 Chevy (1500, 2500, whatever it is) wiring diagram". When you get to the page click images.
I have seen some diagrams in Chiltons and Haines auto repair manuals. I you have a Public Library near by you can go to the reference section and look for Motor Manuals. Most librarys whont let you check them out but you can photo copy them. Another source is the Dealer. They will charge you to copy, if they have the book. You can look on the internet I have seen someone out there advertizing wiring diagrams, but don't remember who.
