Quoting myself from post #12, above, "The way the fuse is wired, it protects all of the interior switch and console illumination except for the two bulbs in the instrument cluster. If the fuse blows, you will be left with the cluster illumination only; all other interior lamps will go dark."

If your lights work even though you have no fuse in the socket, then your car has been modified by someone, somehow.

Thanks.

I'm having a problem because the oil pressure gauge has stopped working since I removed my odo last night. I have everything plugged back in and its not working. Also the RPM gauge is not reading correctly either. It says I am idling at 300rpm and it hardly spins up at all when I drive.
