Out of no were my boost gauge just stopped on me. Not too sure what it could be?

 

Is it still lit up? That will eliminate an electrical issue. Otherwise gauge might be shot IMO

 

Yea the back light is still illuminated. I had bought another stock boost gauge awhile back from someone on here. It was from an 07 SS/SC but the hook ups were completely different! Mine has 1 plug coming out of the back that's all. This other one had 2 wires and a brass port to screw in a boost pressure line. I don't get it?
