Picture 5 of 6 from Album Ignition Kill Switch (EOC)
Here you can see the relay that interrupts the current that goes the the ignition coils. It is connected to the normally closed contacts, and when the ignition kill switch is presses, the relay is energized momentarily opening the contacts, thus turning off the engine with out turning off the engine control module, this way the Scan Gauge keeps communicating with the ECM.
