It might be possible to interface with the speed sensor, break sensor, or cruise control clutch switch. If anyone can think of an easier way (maybe what the commercial units are using) it would be helpful!

You can monitor the yellow wire on 2 pin connector on the side of the keyswitch assembly. It is the key sense wire and it goes to ground when the key is inserted.

Remote starters actually watch the brake to turn off. You have to turn the key to the one position before pressing the brake, otherwise the car shuts off. The brake is also the safety, as pressing it immediately kills the running car.
