This one is a few years old. Still works perfectly though..
It looks exactly the same as per my link. I can remember there are the boost pressure hole from the intake, and 2 wires for the light.
No data link or sensors.. Sorry... And it has vacuum but i think it only goes up to 1.5kg/cm instead of 2.0 which is probably better coz i would assume most ppl wont go in excess of 25psi boost...
Its just your normal greddy mechanical boost gauge...
