So I want to add a push to start button, but instead of just adding it and requiring a key, I want to add it in place of the key. I figure I can use an alarm output (viper 5900) to send a 30 second output when the alarm is disarmed, and that will enable the remote start button. After that, the switch will not start the car. I figure that is an effective way to ensure that if the alarm is disabled by a thief, the switch will not be enabled , so they must figure out how to hotwire the car now, and can not simply jam a screwdriver in the ignition.

Thoughts?

 

Easy enough, install a relay on the starter lead, [N/O] use the 30sec. output to energize the relay, done deal. 94

 

Sounds good but how are u going to unlock the steering column and turn the engine off??
