Inertia switch? Putting an 81zx drivetrain, 78 wiring harness, in my 74 260z. Eliminated EFI and going carbuerated. Going to install the inertia switch on the passenger side of trans tunnel behind the seat. Think this is a good way to cut fuel to the electric pump in case of accident. If it does happen to trip then it's within reach to reset. Should have it all figured out in the next couple of weeks.
