I need a simple guide to which fuses are for what. I just purchased a used 1992 Bonneville that didn't have an owners manual. The fuse box is not labled in any form or fashion. My gas guage and RPM guage are not working and I don't know which fuse to check without pulling them all. If anyone has or knows where I can get a .pdf file or image file that shows the fuse box diagram, I would be greatful. Thank you.

you dont need the owners manual to see the diagram.

On your car there is a drop down fuse block right above the driver side foot well. ON the cover it gives the diagram of the fuses. There is also another fusebox that is in the corner of the passenge foot well. The diagram for that one is on the hushpanel, you will need to remove the hushpanel to get to that fuse box

Thanks, John. You beat me to it! Welcome to the land of free owner'* manuals.

There'* another fuse panel on the passenger side foot well? Or are you talking about the Relay Box under the hood on the passenger side?

I'm in a bad way...I have a poor, beat-up, sad little '92 SSE that came from a rental fleet (over 230,000 miles). No owner'* manual, no fuse box cover, no user'* manual for the '92 here on the site...I was lying underneath the dash tonight to see if it was a fuse that is preventing my top mount brake light from working and noticed that there is an empty slot. I thought that probably isn't good, but I have no idea what the amps should be or what it is for...( turns out the brake light was a corroded socket, replacing that tomorrow). At any rate, any help for the fuse box ID? I might be willing to pay for a manual rather than pay a mechanic. There is NOT a diagram in the Haynes...

Thanks for the help!
