Hell, I was souring through to see how they made it fully analogue.

A stupid title.

Most likely step motors in the instruments. I am sure there is no analog voltage or pneumatic input to the dashboard.

Neither was there in cars with dials 30 years ago.

The speedometer and odometer at least could be fully mechanical: they used to be gear reduced from a cable to the wheels or transmission.

That's the point, they could've hypothetically been analog but even in a 30 year old car they most likely weren't.
