Default electronic tach conversion
I have placed a 1975 electronic tach in my 74 coupe to match the hei distributor. There are three male spade connectors on the back of the tach, I would assume they go to the tach filter, +12V and ground. They are not marked on the back of the tach and I have not found a wiring schematic that says which pin is which. Does anyone know the pinout?

Thanks.
