timing circuit diagram

I  am trying to find a timing circuit to add to an auxillary output on my car alarm that will disable the car when I press a button on my alarm.I want this timer to activate after 30 to 90 seconds.The alarm already disable starter but car thieves here in Jamica know about alarm starter kills so I am looking to disable another circuit in the car. I have a 2004 Hyundai Sonata.

Directed Electronics has a module called the 528T. It's a timer which is initiated by a pulse. The install manual is already on this site in the "downloads" section.Prepare your future. It wasn't the lack of stones that killed the stone age.

Thank you very much
