This has been on my list for a few years and since I have the console out I was asking myself -- why not just wire a toggle into one side of the neutral safety switch -- so that it creates an open in the purple leads. Now, I know that this is far from theft-proof as you could still start the car using a screwdriver across the starter. However, I'm trying to create something that's an annoyance as it would take about 7 steps to make this car theft resistant (I have a convertible and no way to lock the hood -- so really if you know what you are doing, you can start the thing... without much work). I'm less inclined to start running wires to the coil - although I know that would be more effective. Is this a total waste of time? Am I missing something obvious?
