* Online Parts Websites: Sites like ClassicParts.com, LMC Truck, and others that specialize in classic Chevy parts often have wiring diagrams available for purchase, either as part of a repair manual or as a standalone download. They might be digital downloads or printed copies. Search their websites for "1966 Chevy truck wiring diagram."
* Online Forums and Communities: Dedicated Chevrolet truck forums (search for "1966 Chevy truck forum") are excellent resources. Members often share knowledge and sometimes even scanned copies of diagrams. However, the quality and accuracy can vary, so always cross-reference with other sources.
* Repair Manuals: A Haynes or Chilton repair manual for a 1966 Chevy truck will almost certainly include a wiring diagram. These are readily available at auto parts stores, online retailers (Amazon, eBay), and sometimes even libraries. These manuals often provide more detailed information than just a diagram.
* eBay: You can sometimes find original or reprinted wiring diagrams on eBay. Be cautious and check seller ratings before purchasing.
* Your Local Library: Some libraries have collections of repair manuals that might include a 1966 Chevy truck wiring diagram.
Important Considerations:
* Truck Specificity: Wiring diagrams can vary slightly depending on the specific model (e.g., C10, C20, C30) and options (e.g., power windows, air conditioning). Be sure to specify the exact details of your truck when searching.
* Accuracy: Always verify information from multiple sources, especially if undertaking significant electrical work. An incorrect wiring diagram can lead to damage to your truck's electrical system.
Start by searching online parts websites and forums. If you can't find a free diagram, a repair manual is a worthwhile investment as it contains much more valuable information than just the wiring.
