See response from the convertible alarm thread: http://www.1addicts.com/forums/showthread.php?t=662125

Edit: When I ordered from the dealer in September 2014, they started quoting me individual parts. The siren was like $260 CAD or something by itself, ultrasonic sensor was over 100, but the whole kit was $330 CAD including everything in the breakdown below. This was my experience, your dealer could very well give you different info. The convertible kit will not work on the coupe though because the siren bracket is different. Only the hood switch + bracket and siren will transfer over. You would need to pick and choose the parts you want via the part numbers below.
