WTB: Stock boost gauge for 02 WRX

I am just looking into it right now just to get me by till I can get a gauge pod and the right gauges, I have a few questions first though.

Is it easy to hook up?
Is there a plug it just plugs into beings it is a stock option?
How arcurate are they?

 

pretty easy to hook up, the only thing you would hafta do that would be destructive is you'de hafta drill holes in your steering column, yes there is a plug behind the stereo that it plugs into, (well its behind the stereo on GCs)

 

Thanks, how big of holes are we talking? Sorry for the lack of knowledge but what does GC mean?

 

the holes you drill are only as big as the screws provided, and GC is the body style, 2001-1993 impreza sedan/coupe is GC, 02-present is a GD i believe

 

Thanks
