Hello everyone. Just got a 2012 larado x 5.7 im trying to find the ignition wire so i can tap a siren into. basically i need a wire to turn over the relay which will then give the siren power. Anyone know where i can grap a wire that is hot while the car is on and off when the car is off. The siren is mounted ontop of the battery under the pass. seat. so if theres a wire anywhere close to that i would greatly appreciate it. Thanks to anyone that can help or atleast point me in the right direction.
