Where is a Fuse diagram for 1990 corvette?

You won't find a single, readily available online image that's universally accepted as *the* fuse diagram for a 1990 Corvette. The location and specifics vary slightly depending on options installed in the car.

Your best options are:

1. Your Owner's Manual: The most reliable source is your car's owner's manual. It should have a detailed fuse box diagram.

2. The Fuse Box Cover: The inside of the fuse box cover itself often has a diagram printed on it.

3. Online Repair Manuals: Websites like HelmInc.com (the official GM parts and manual source) sell factory service manuals. These manuals have extremely detailed electrical diagrams, including fuse box layouts. These are the most comprehensive but cost money.

4. Third-Party Repair Manuals: Sites like eBay and Amazon often sell third-party repair manuals for the 1990 Corvette. The quality varies, but they often include fuse box diagrams. Be sure to check reviews before purchasing.

5. Corvette Forums: Search Corvette-specific online forums (like CorvetteForum.com). Someone may have already posted a picture of their fuse box diagram, but be aware that this is less reliable than your owner's manual or a professional manual.

Remember to always disconnect the negative battery terminal before working with fuses or electrical components to prevent damage or injury.
