I have the same switch in my Spec Boxster.

Wiring the power cutoff switch direct to the ECU is important because this is the only way to be sure that the fuel pump will immediately be turned off. Turning off the engine but leaving power to the ECU will leave the fuel pump powered and pumping - not a good thing in an emergency situation.
