Trying to find the wiring schematic for a 1966 442 tach on the console. Should be just a basic thing few wire installation but I cannot be sure. Anyone have one to share or guide me through?
Thank you

 

No 1966 came from the factory with a tach on the console. That was 1964-65 only. In any case, here's the 1965 wiring. Brown goes to the coil, ground is black. The light bulb wire goes to the grey illumination circuit.

 

Thank you for the prompt response! We are working on it right now and this is so helpful
