Haynes and Chilton manuals are available for purchase from most auto parts stores. They usually have wiring diagrams. These are usually around twenty dollars. As of today, a Haynes manual is listed on rockauto.com for 14.95. It's under the category Literature.
I bought the Haynes book..its worthless the only diagram of any value is the starting/ charging page and that is easily found on the web for free..alldatadiy has way better printable pages and diagrams..
