There's a few good spots that you can wire a kill switch up to. Personally I wouldn't bother with the ecm it's not worth the hassle.
A quick and easy way to kill it would be to wire a switch to the power supply for the fuel pump (don't forget that there's two feeds to the pump, one from the fuel pump relay and another through the oil pressure switch). So grab the positive power lead at the pump, cut into that and wire a switch there. Simple and effective. No fuel means no go.
One that takes a bit more effort would be to wire it into the Crank Angle Sensor. This is what tells the engine the location of the crank, which tells it when to spark. If it doesn't know where the crank is then you can't get spark which means the engine won't run.
Another good one would be to tap into the feed wire for the injector fuse. If no power goes to the injectors then you won't get any fuel in there.
If you're hell bent on wiring a kill switch to the ecm for some god unknown reason, then tap into a straight GREY wire, this runs to the starter relay. Cut that with a switch and you can't start the car. |

| I got a key switch set up in a secret place, flick the key and the engine turns over until the battery runs out but wont start. Dont know how it was done but im guessing by no fuel since the car doesnt flood. Pain in the ass when you forget its on though... |

Probably be hooked up to the injectors.
If you really want to stuff with their heads, swap it to the fuel pump, there'd be enough fuel to get it running, but as soon as they do anything like put it in gear or touch the throttle it dies. Only problem with that is that it tends to kill your catalytic converter. |

| By kill switch do you mean imobilser?? |
What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

| Well not really a kill switch is a maunal switch which is hidden in the car which you need to turn everytime you start the car. It's the same sort of thing as an imobilser but it's not electical or controled by a remote. But they do the same sort of thing. |
