My emergency brake light was on when I turned on the car on my drive home from work. Its cold out, and I think that my mastercylinder switch acts up when cold. All the fluid levels are fine.

Now the strange part...

When I pushed in my clutch, the light turned off. Let out the cluch, the light turned on instantly.

I'm trying to find the wiring diagrams on this, but was hoping to get some suggestions.

 

Ok, I did some more searching of the electrical diagrams in my shop manual. So the brake light circuit for the gauge is hot (yellow wire) on one side, and normally gets ground from the brake fluid switch or parking brake switch.

Somehow the cluch switch (when the car is in gear and my foot is off of the clutch) is supplying that ground.
