thanks in advance, Hon

Answer
Hi,

The ground-when-armed (GWA) wire you're looking for is coming from the car alarm unit.  It does just what it says: when you arm the alarm, the GWA wire is connected to chassis ground, and stays that way until the alarm is disarmed.  It's most often used with a starter kill relay.  When connected to your 530T, it will make  your windows roll up automatically when you arm the alarm.  

To find the GWA wire color, I'd need to know the make and model of the alarm itself.  On a Directed family alarm (Viper, Python, Avital, Clifford, Sidewinder, Hornet, Valet, etc) the GWA wire is typically orange.

Hope this helps!
