Check with the dealer. I have a 2004 1M 900. It runs when the ignition is open circuit. Typical tethers open circuit when pulled, so the machine continues to run. You might need a tether that 'closes' the circuit when pulled?
KIll the registry. There's a lot better things that a billion dollars could go toward. Can't tell me that it scares off those on the wrong side of the law. :rant:
