Anyone wanna wire a Police Siren to the S4 car alarm? so when the alarm goes off...
The trick is that the triggers for the horn and alarm need to be electrically isolated using a diode so that they don't both sound when one of them is triggered.

if you're concerned about theft, pickup a better alarm / disklok / random cutoff switches / pulling fuel pump fuse
or a rayvelco
