Vehicle Security System?

Looking at SEC-126 of the 2009 FSM, the doors have switches that sink a BCM pin to ground when the door is closed. If I read things right (SEC-21), opening the door will trigger an alarm. Put your tilt switch in series with one of the door switches so that the tilt switch opens when tilted. The hood switch circuit will probably work the same way but I didn't see it in the wiring diagram.

I am surprise that nobody has added a shock/tilt/motion sensors. It is useful in case someone what to steal the wheels, smash windows or bumps into your car.

No alarm here, I just opted for a lo-jack, which has something like a 98% recovery rate if the car gets stolen. There's more valuable cars out there if someone really wants to go through the hassle of getting past the immobilizer.

This is cool and all but has anyone one wired in a train horn?
