So I thought that I had 1963 340HP buzzer tach with out the buzzer. It turns out that is does have the buzzer but since there are no wiring diagrams, shop manual, Doc rebuild's, great one, or any place else I have looked that show it, where does the red/pink long wire plug in. It clear that the blue wire with small circular connector plugs into the back of the tach. I would post a picture but I am having trouble with that.
