My tach is intermittent and I want to check all connections. I see the grey wire leaving the tach mounted in the dashboard. Does this wire go directly to the motor or is it terminated in the driver control panel where the gear shift, speed controls etc are? When it reaches the motor what terminal is it connected to?

Ensure +12 volt and ground connections are clean and tight -- on both ends. Loose power and ground can also cause intermittent operation. The tech wire ends up at the rectifier/regulator.
