Rev counter wiring

[Bigbear]

I bought a rev counter from someone who was making them on here a few years back, the one that fits into the blank on the cluster, has anyone got a picture of the wiring diagram for it?

Was it from Aspro? I can't help but I'm sure he will be able to tell you how it goes

Rev counters are all the same. Ignition live, earth and signal to the - on the coil

Does anyone have a tacho from aspro? Is it possible anyone could tell me what cable goes where out of the three connectors on the back? I seem to remember having to fit a diode aswell?
