You got it right. It's just a switch that upon impact cuts the power or ground in this case to the fuel pumps. With no fuel, the engine stops running, which is what the blue switch does on the back of the flapper housing. It won't do anything to emissions and evrything can be left in place.

If I had to guess, if you get in an accident and the car stops abruptly, the switch will sense G's or inertia and shut off the the fuel. Am I right.

Also, what does it replace, how do you buy it, and would this effect my ability to pass emissions in any way (I'm guesssing no)?

Thanks again,
