I was wondering if anyone has tried ro knew how to hook up a small ringer or buzzer that can be triggered to go off at a certain RPM? I wan't this instead of a shift light because it would be easier to hear than see a shift light mid corner. I know that RX-7s have something very simialr to this. I'm not sure how those are set up. Any electrical people out there know how and where to hook this up to?
