Boost gauge hookup

I have a 2009 2LT and just bought a working stock SS boost/vac guage for a cheap $35.00 and bought it mostly for it's vacuum reading. Does anyone know which wires I need to connect where to make it work?

Thanks

I believe the signal comes from the ECU. You probably want to find a manual gauge.

There are gauges made specifically for reading vacuum...

Damn. I was hoping you wouldn't say that it was the ECU.

Anyone want to buy a stock vacuum gauge for $35.00
