My best guess would be that you'll have to remove the dash and hunt down the wire that is either shorting or crossing exposed ends. It'll be in the area near pedals if they are affecting the problem, and also look around headlight switch area. It's basically just hunting down which wire is crossing where. Good luck.

Side note: Easiest place to start is look at where all affected areas would come together or their wiring would meet up.
