Ground is black.
I've found the main instrument cluster ground unplugged from the buss bar above the parking brake pedal more than once. Easy quick fix.

I miss spoke the only gage working was the oil pressure gage but it was pegging out then reading normal . I traced it to the sensor behind the distributor. I had fixed that but took it out to install the mechanical gage
Dash Lamps are working fine
