* Repair Manuals: A Haynes or Chilton repair manual specifically for a 2000 Chevy Silverado will have a detailed wiring diagram section. These are available at most auto parts stores and online retailers.
* Online Automotive Repair Databases: Sites like AllDataDIY, Mitchell1, and others (often subscription-based) offer comprehensive wiring diagrams and other repair information. These are usually more detailed than what you'll find in a general repair manual.
* Factory Service Manual: A genuine factory service manual from GM (if you can find one) will be the most accurate source, but these are often expensive and difficult to obtain.
* Online Forums: Searching Chevy Silverado forums (like those on sites dedicated to automotive enthusiasts) may yield results. Someone may have already posted a diagram or a link to one. However, always verify the information found on forums as its accuracy isn't guaranteed.
* Auto Parts Store Websites: Some major auto parts store websites (like AutoZone, Advance Auto Parts, etc.) might have some basic wiring information, though it's often less detailed than a dedicated repair manual.
When searching, be as specific as possible. Mention the year (2000), make (Chevy), model (Silverado), and trim level (if known) to ensure you get the correct diagram. The radio type (factory or aftermarket) might also affect the wiring. If it's a factory radio, the wiring harness will differ from an aftermarket installation.
