ok i want to set up some like custom security shit on my car .. my alarm had sidemarkers and i cut them .. when my alarm would go off the side blinkers would blink .. so now i have a power / ground i can do something else with .. heres the challenge .. i was thinking about how you could set up some sort of like rader signal something to that power/ground which would set off like a horn in my room? one time my system got robbed because i didnt hear the alarm .. i know this sounds stupid and i probably will get flamed but i was wondering if someone could give me any help on a way to do this? .. i was also considering just running a power/neg wire to my house w/ a car horn and just have a plug to plug/unplug it from the car .. i dunno .. just ideas .. thanks
