There is not an easy way to do this as far as I know. What we had to do on mine is trick the car into thinking that it was off even though the turbo timer was still running. We used relays to read when the accessory turns off and then sent that signal to the alarm brain telling it that it could arm.
But since yours is a factory you will need to search and find a wiring breakout for the factory alarm and find the wire that controls the ability for the alarm to arm and figure a way to change it so that when your accessory goes off it can be armed.
