Hey everybody im new to the board i spent about an hour searching the boards for this answer and found nothing that helped me out i need to know where the amp relay for the alarm is i dont know if my alarm is stock or not im assuming it is because the person i bought the car from bought the car with that alarm on it. If anyboy can help me out please do i need to know where this part is.. its the part that controls the lights and the sirens when the alarm goes off it might also be the brain but in the installation instructions for my deck it says amp relay thanx
