Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
This would depend on the tacho you're trying to install, but most commonly these require a positive line, a negative line, and a signal.
The positive and negative should come from the battery, and the signal line most come from the ignition coil (on the negative side of the ignition coil).
Thank you for your trust! Get back to me if you need more assistance...Thank you in advance for the positive rating...
Regards,
Billy
