Hello! You may or may not have read my other thread, but my friend is still internetless and has another question.

His Prelude's tachometer is buggered. It appears to be a loose ground or something, as the needle bounces around wildly. I would like to help him fix this, but I am unsure of where the wiring is located. Does anyone know? Or better yet, does anyone have a diagram?

ANy help would be greeatly appreciated.
