Greddy Electronic Gauges Install Q

[Jim96SC2]

I just got my Greddy Electronic Boost Gauge and now I need to hook the darned thing up. It says to hook one wire up to the ignition power. Does anyone know what wire this would be or which wire I could substitute?

I'm gonna throw the 12V power source onto the dimmer switch, sound good?

Thanks!
