* Your Owner's Manual: The most reliable source. Check the manual's electrical section, often towards the back.
* Online Repair Manuals: Websites like Haynes.com or Chilton.com (subscription may be required) offer detailed repair manuals including fuse box diagrams. Search for "1992 Ford Mustang repair manual" on their sites.
* Ford's Website (Possibly): While less likely to have a full diagram, Ford's website might have some basic electrical information or links to manuals.
* Online Forums: Search Mustang-specific forums (like Mustang forums on Corral.net or others). Someone might have posted a picture or scanned copy of the diagram.
* Under the Hood: While not a diagram, the fuse box cover itself *often* has a small legend printed on it identifying some of the fuses. This isn't comprehensive, but it's a starting point.
Important Note: There are usually multiple fuse boxes in a car. A 1992 Mustang likely has one under the hood and potentially one inside the passenger compartment (often under the dashboard). Make sure you're looking for the diagram of the specific box you need. Be cautious working with electrical systems and disconnect the battery's negative terminal if you're working directly on the fuse box to avoid accidental shorts.
