For my boost gauge, i need both a grounding point and a power supply to lightit up. I'm pretty sure i'm going to use the 14ga red wire which comes up from the ignition switch as a power source (unless their is a much easier one; i'm all ears!) but where should i ground it? NOt really an electrician, so any help is appreciated.

kenny (dremel)

ground it to the 8mm bolt behind the fuse panel cover.
