Well to start the car is an '86 Z28 that i bought comepletly gutted. Now it has most everything to get it running. All i want wired up for now is the switchboard i fabbed up (pic below). I have the starter on a momentary toggle, the ignition on a keyed switch, and the rest are all stationary toggles. So what guage wire do i use ? where do i put and how many grounds? Can anyone draw a diagram of how i should go about this?
