Wiring4cars.com offers model years 1965 through 2015 for all American cars, trucks and vans. The wiring diagrams are rendered in PDF format for ease of viewing. In addition, the site offers component-specific diagrams for components like power windows, radio wiring and air conditioner circuits.
Freeautomechanic.com also offers free wiring diagrams that are delivered in PDF format. The site does not maintain a searchable database, but instead it takes requests for wiring diagrams and returns the diagrams via email to requesters. It can take up to a week or more for a response when requesting non-published diagrams. Although the wiring diagrams it offers are free, the site requests donations of up to $5 for the time taken to research and send the diagrams to requesters.
