Don,
Maybe he will return your unit?
ACtually you need to install a relay so your alarm wont trigger or unlock the door locks once the car turns off. Also, some alarms have a wire that desensitises (SP?) the unit so it does not pick up movement. This is for those cars that have remote start. The relay will use that feature so the alarm wont trigger.
Also, if you want you can get this one alarm that has a built in turbo timer. I forgot the name of the unit though.
