Go to the dealer and get a new siren correct for your vin number. If you keep asking reiterated questions someone is going to tell you to buy it and if it's the wrong part you'll look like a fool
explained all that a while ago, but this guy only wants to hear what he likes.
Let him buy and pay with fleabay, and report back about the results!
