I was wondering how to make my alarm chirp while driving with the push of a button. My old car did it but the person who installed the alarm took care of it all. I am guessing you run a button to the siren itself and a 12v source with the button opening and closing the cuircut. If anyone can lead me in the right direction i would be most greatful. (it's just fun to have.) Later.

 

They sell them seperately, they are call like whoop sirens, for like 30 dollars installed

 

just run a wire from the a 12v source to the switch and then to the positive side of the siren, usually a red wire connected to a brown wire comming out of the alarm box, check a wiring diagram to be sure
