Here are the best places to look:
* Chevrolet Service Manuals (1964 Impala): This is your best bet. A factory service manual for a 1964 Chevy Impala will contain detailed wiring diagrams, including those related to the automatic transmission (Powerglide or Turbo Hydra-matic, depending on the model). You can often find these manuals:
* Online Retailers: eBay, Amazon, and other online marketplaces often have scanned copies or reprinted versions. Search for "1964 Chevy Impala service manual."
* Specialty Auto Parts Stores: Some auto parts stores may carry reprinted manuals.
* Online Automotive Forums: Check forums dedicated to classic Chevrolets (e.g., forums on sites like Chevelles.com or the Impala-specific forums). Someone may have a scanned copy they can share.
* Online Wiring Diagram Databases: Some websites specialize in providing wiring diagrams for older vehicles. However, finding one specifically for a 1964 Impala's automatic transmission might be challenging, as they often focus on the entire system.
* Haynes or Chilton Repair Manuals: While these manuals are generally less detailed than factory service manuals, they might offer simplified wiring diagrams that could be helpful.
Important Considerations:
* Transmission Type: Specify whether you had a Powerglide or Turbo Hydra-matic transmission. This will greatly narrow your search. The 1964 Impala used both, and the wiring will differ. Your vehicle's VIN will help you determine the exact transmission.
* Diagram Detail: Be aware that the level of detail in diagrams varies. Some may show only major components and connections, while others might show every wire and connection point.
Remember to always disconnect the negative battery terminal before working on any electrical components in your vehicle. Incorrect wiring can damage your car's electrical system.
