The clow nose and light flash can be programmed without the other components. Further more you can buy a pizeo siren from radio shack for about $7 and pin it into the existing connector behind the ac blower. I mounted it in the drug bin on my Xi and it worked fine. However as others have said the fob has a laughable range so as a marco polo mod it's fairly useless.
