I am posting this here because nothing else makes sense

All I know is that the battery was not disconnected. It is now. I have a good fire extinguisher in the garage, but this was a cheap one I put in the car, I guess for just this event.
The only thing was the turn flasher was hanging near by where the fire started. I checked it and I do not believe it was involved.
I have examined the wiring and have replaced much of it. Primarily in the engine compartment and drivers side behind the dash. If I ever figure this out, rest assured I will post it here.
