i bought the SPT Boost Gauge from Subaru Online Parts .com
but after i installed it, it didn't work.
no boost reading no lights nothing.
i double checked everything but still no go, i took it to an electrician and he told me it might be because it was bought from the US and my car is Japanese spec.
any idea if this could be the reason ?
and does anyone have wiring diagram for this thing ?
i'd appreciate your feedback
