Tacho connections please

Can anyone help with the connections for a Xj tach? I assume one is direct to +ve and the other to the distributor side of the coil?

I have nothing for the XJ but the S3 wiring has a green wire (hot) that passes through the tach then goes to the ballast resistor via a white/blue wire.

Just wondered which pin is which?

Can’t help you with that. Someone on the XJ forums can probably help, you definitely need precise instructions.
