Built-in charging pressure gauge

Hi everyone,

I'd be interested to know how you implemented a boost pressure gauge as a permanent installation in a Golf 3. What instruments did you use (manufacturer) and where were they installed?

-1 to 1.5 bar from LR (Conrad), installed on the left side next to the radio compartment.

Hi

a semicircular display in the upper right corner of the instrument panel (next to the DZM, at the same level as the standard displays).

Looks like it's factory-installed, except for the handwritten scale

The part is from a R5 Alpine Turbo.
