* Your Owner's Manual: The owner's manual that came with the car (if you still have it) might have a simplified diagram or at least list the firing order.
* Haynes or Chilton Repair Manual: These aftermarket repair manuals are widely available for most car models, including the Caprice Classic. They often contain detailed wiring diagrams and specifications. You can usually find these at auto parts stores or online retailers like Amazon.
* Online Automotive Repair Databases: Websites like AllDataDIY (subscription required) or Mitchell 1 (subscription required) provide comprehensive repair information including wiring diagrams for various vehicles. These are often used by professional mechanics.
* Online Forums: Searching online forums dedicated to classic Chevy vehicles (like those on sites like Facebook groups or dedicated car forums) might turn up someone who has already posted a diagram or can help you find one. Be sure to specify the year of your Caprice Classic as the specifics may vary slightly between model years.
Important Note: The firing order is crucial for the engine to run correctly. Getting it wrong can cause misfires and damage. If you're unsure, consult a reliable source before attempting any work on the ignition system.
