i just installed my indiglow door sills and i followed the write ups that i got from people online! and after arming my stock alarm it goes off on its own once a while!! can someone tell me what can be the cause of this?????

 

Never had that prob before with mine. Check the connections make sure they arnt shorting. Otherwise

 

sounds like you need a diode somewhere. On some cars, like mine, the alarm will go off sporatically if the map light is left on. Maybe you have a circuit being made there.
