Check engine light popped on, stock boost guage doesnt work?

[Spoolio]

Hey i started my car, my check engine light popped on, and my stock boost guage doesnt move, and my car is running so rich its rediculous, it literlly burns my eyes, also its just running like complete azz now, it was perfect when i turned it off, it seems like something popped off or blew?, idk , anyone know where the stock boost guage hookup is?, where the wires go, or to what sensor?, or what should i do?

Found the problem it was the safc I installed. It was bad. Had a boy come over with a safc and it idle smooth. Removed it and everything back to normal.

2g mass installed intermittin check engine light and spudder, turns out the 2g mass connector didnt make good enough contact, slightly bent the pins on the 2g mass. Made for a snug connection when the harness connected, also corrected the problem of the cel and intermittin spudder.
