* Factory Service Manual: This is your best bet for an accurate and comprehensive diagram. You can often find these manuals on online retailers like eBay, Amazon, or specialized automotive parts websites. Search for "2000 Ford Mustang GT factory service manual." These manuals are usually quite expensive but provide the most detailed information.
* Online Automotive Repair Databases (Subscription-Based): Websites like AllDataDIY, Mitchell 1, and Chilton offer online access to repair information, including wiring diagrams. These usually require a paid subscription, but they often have very detailed information.
* Ford Dealerships: A Ford dealership's service department might be able to provide you with a copy of a wiring diagram, either for a fee or potentially as part of a service.
* Online Forums: Automotive forums dedicated to Mustangs (like Mustang Forums or others found through a Google search) might have members who have scanned sections of a wiring diagram or can point you toward a reliable resource. However, be cautious about the accuracy of information found in forums. Always verify information from multiple sources.
Important Considerations:
* Specificity: The wiring diagram you need will vary slightly depending on specific options your Mustang GT has (e.g., different sound systems, optional packages). The more detailed information you can provide (like a VIN number if possible), the easier it will be to find the exact diagram you need.
* Accuracy: Be wary of unofficial sources. Incorrect wiring diagrams can lead to serious problems with your car's electrical system. Prioritize official sources whenever possible.
Start with searching online retailers for the factory service manual. That's your best chance of getting a reliable and accurate wiring diagram for your 2000 Mustang GT.
