Yes yes I know it's probably a ground issue. But in this case I ran two ground jumpers from the case to a known good ground where my aftermarket gauges are grounded. So while I agree it's a ground problem I think it has to be the printed circuit card itself.

Still not all of the factory gauge lights work. Notably the left turn signal. All the bulbs are new. It is missing a single of the black bulb carriers and it's bulb. I tried to buy new ones but both rock auto and Orieleys gave me ones that were too small. I don't know if missing one of those I completed a circuit. Doesn't look like it should.

Also sorta unrelated. Should the turn signal switch itself turn off automatically when you make your turn. Or do the old cars require you to manually put it back in the mid (off) selection.
