No vacuum line in my boost gauge?

[CraGle]

my new glanza, come with 3 gauges, oil temp, oil pressure and boost guage, they are wired up, but not working....

I take the back off the boost gauge to discover no vacuum port.

Its a prosport gauge..

Any help would be much appreciated.

Thanks.

Edit : Just found outs in an elecrtic gauge, any idea where i find a boost sensor in the engine bay???

Thanks agen

only way to find it would be to follow the electrical wiring back through the bulkhead and so the sensor, it's probably in there somewhere, there's only a few rubber bungs so look behind the engine for where it pops through and follow the wires.
