Here's why and where you might look:
* Copyright: Wiring diagrams are copyrighted material. Auto manufacturers don't generally release them for free public distribution.
* Complexity: The electrical system of a car, especially one with features like hideaway headlights, is complex. A poorly drawn or incomplete diagram can be more harmful than helpful.
* Where to look (but expect to pay):
* Factory Service Manuals: These are your best bet for accuracy. You can often find them through online retailers specializing in classic car parts and manuals (e.g., eBay, Amazon). Expect to pay a significant price.
* Online Retailers Specializing in Auto Repair Manuals: Websites that sell repair manuals for various car makes and models sometimes offer wiring diagrams separately or as part of a larger electrical system guide.
* Classic Car Clubs and Forums: Dodge Charger clubs or forums dedicated to Mopar vehicles might have members who have scanned portions of a wiring diagram and are willing to share them, but a complete, accurate set will be rare.
Before you start working on your electrical system:
* Safety First: Disconnecting your battery's negative terminal is crucial before working with any car's electrical system.
* Careful Inspection: Before resorting to a diagram, carefully trace the wires yourself. Sometimes, you can figure out a simple circuit by following the wire's path. Labeling what you find as you go helps.
Finding a free diagram is a long shot. Investing in a proper service manual will ultimately save you time, frustration, and potential damage to your car.
