  9. Laura, the placement of car alarm valet switches are dependent on the car alarm installer. Our advice is to take your car to a qualified alarm installer and ask them to find the car alarm valet switch. Any experienced car alarm installer should be able to locate it. Hope this helps. Good luck with finding your car alarm valet switch.

  19. Eddie, as much as we would like to help you, not all car alarms are installed the same way. Different brands and different setups will call for different wiring. Our advice is to take your car to a qualified alarm installer and ask them to remove the alarm because it does take some wiring knowledge and experience to know what to remove. Hope this helps. Good luck.

  26. Mandy, an auxiliary channel output wire is not the same as the accessory wire.
