* Under the Hood: A fuse box is usually located under the hood, often near the battery or on the inner fender well. This box typically contains the larger fuses protecting higher-amperage circuits.
* Under the Dash: Many 1965 Mustangs also have a smaller fuse box located under the dashboard, usually near the steering column. This typically houses smaller fuses for interior lights, accessories, and other lower-amperage circuits. This location is less common than under the hood.
To find them definitively, you should:
1. Consult your owner's manual: If you have the original owner's manual, it will have a diagram showing the fuse box location(s) and a fuse panel layout.
2. Look closely under the hood and dash: Systematically check near the areas mentioned above. The fuse boxes are usually easily identifiable, being rectangular plastic or metal boxes.
3. Use a 1965 Mustang wiring diagram: A wiring diagram specific to your Mustang's options and model will clearly show the fuse box locations and what each fuse protects. These diagrams are available online through various Mustang restoration parts suppliers and enthusiast websites.
Without knowing your specific Mustang's configuration, it's impossible to give a more precise answer. Use the suggestions above to locate your fuse boxes.
