Here are the best places to look:
* Factory Service Manuals: These are the most reliable source. A factory service manual specific to your Challenger's engine will have detailed wiring diagrams, including the ignition system. You can often find these online through eBay, Amazon, or specialized automotive parts websites that sell repair manuals. Look for manuals that explicitly mention your engine size.
* Online Forums and Communities: Websites and forums dedicated to classic Mopar (Dodge, Plymouth, Chrysler) vehicles are excellent resources. Members often share repair information, including diagrams, and can help you identify the correct diagram based on your engine code. Try searching on forums like Allpar or Challenger forums. Be sure to provide as much detail as possible about your car (engine size, options, etc.).
* Online Parts Websites: Some online parts websites (like those selling parts for classic cars) may offer wiring diagrams as part of their resources or may have access to them if you contact their customer service.
* Haynes or Chilton Repair Manuals: While generally less detailed than factory manuals, Haynes and Chilton repair manuals often include simplified wiring diagrams. Again, ensure the manual covers your specific engine.
Important Considerations:
* Engine Code: The engine code (usually stamped on the engine block) is crucial for finding the correct diagram. This code will help narrow down the search.
* Specific Components: If you're looking for a diagram of a specific part of the ignition system (e.g., the ignition coil wiring), mentioning that will help others understand your needs.
Remember to be cautious when working with automotive electrical systems. Disconnect the battery's negative terminal before working on any wiring to prevent accidental shorts or damage.
