Kyle, I'll check with Prosport...
I got 5 from them... Water temp, oil pressure, fuel pressure, peak and hold boost and a peak and hold egt gauge...
I havent checked the wiring schematics yet, but if you need an ignition source, you can tap into any igntion source, even the radio... So long as it gets power when the key is turned to on or start, you can tap into it... *pretty much anyway*
