Where did you mount your inertia switch?

i stuck mine on the left outboard side of the clutch pedal bracket. So between the bracket and the fresh air intake box, but forward of the box and also upside down so its easier to reach

FYI, they are direction sensitive. Upside down isn't good.

How they work: there is a small funnel shape with a magnet at the bottom. A ball bearing rests in the funnel held in place by the magnet. There is a big flag on top of the funnel that goes to the trip switch.
When you take a hard hit from the side the ball is knocked off the magnet and ramps up the funnel tripping the switch. Also a hard roll over will just lift the ball off the magnet and trip the switch. But a hard hit from the bottom (hitting a pothole) pushes the ball into the funnel not tripping the switch. A side hit while upside down will have gravity pulling the ball so it is more sensitive.

There is a reason why the trip switch is on the top.

I think D side on kick panel or upper firewall is where it will end up. I'm deleting the fresh air box so I'll have plenty of space up there. Thanks for the info Mark!

Thanks again to all the Experts that make this Forum so Great! I had an oil pressure cutoff switch for my electric fuel pump, but after reading this thread I decided for extra piece of mind and safety that adding an inertia switch also would be a very good idea. Learned how they work and how and where to mount them from this thread.

Did mine on the Passenger side kick panel, as well, to locate it as close to a factory stock location as possible.
