I tried to find another ways to disable alarm siren too, but somehow I always found myself with the same answer.'

Either you try changing battery (which you have already done WRAITH13) or you change the alarm module. I got lucky 'cause my crossfire stopped yelling and flashing lights after battery change.

For me it would have been quite a search to find new alarm module here in Finland. Anyway, I think I'm going to have to replace also the alarm module in these coming years so better start searching one with a decent price.

Wraith. What does "Eurotune" and "Sprintbooster" do?

Buck Spunni. After removing "siren" did it still flash?
