To find a tachometer wire with a multi-meter:
1. Set meter to AC voltage.
2. Attach the (-) probe of the meter to chassis ground.
3. Start and run the vehicle
4. Probe the wire suspected of being the tachometer wire with the other probe.
5. If this is the correct wire, the meter will read between 1V and 6V. This wire will increase in voltage as the RPMs are increased.
See you.
