To find the correct diagram, you need to specify the exact year and trim level of your Mustang. Then you can look in a few places:
* Your Owner's Manual: The most reliable source. Look for a section on fuses and relays; it should have a diagram.
* Online Repair Manuals: Sites like Chilton.com or Haynes.com offer online access to repair manuals (often subscription-based) that contain detailed fuse box diagrams for specific years and models.
* Ford's Website: While they don't typically offer free downloadable diagrams, Ford's website might have some information or direct you to a dealer who could provide assistance.
* Online Forums: Forums dedicated to Ford Mustangs (like Mustang forums on sites like Corral.net) can be helpful. Search for your specific year and model, and someone might have a scan of the diagram they can share. However, always verify the information you find on forums with other sources.
* Your Local Auto Parts Store: Auto parts stores like AutoZone, Advance Auto Parts, or O'Reilly Auto Parts often have access to repair information and might be able to print out a relevant diagram for you.
Important Note: Always disconnect the negative battery terminal before working on your fuse box to prevent electrical shock or damage to your vehicle's electrical system.
