Vehicles with a body coloured instrument panel were originally positive
ground. Black instrument panel means negative ground.
Why originally positive? Why do the Brit's drive on the left? I think that
there was some slight electrical logic to it, but a spark plug doesn't
really care which direction the electrons are flowing. Your stereo sure
does though, I think that's the reason most people have converted + ground
vehicles to - ground.
