As for adding a sound for just addon vehicles, I dont think that is possible. However, if you want new sirens, here is the one I use:

Yeh I’m using that pack atm but the the fire truck siren I’m looking would like a fdny or similar if there is any but I don’t know hot to install just a siren for fire truck so all vehicles don’t have that siren

If I am right, it is the same way you do it for the modern siren pack. Each file for each vehicle has a different name. So the one you want to use should be renamed to whatever the firetruck one is called in the Modern Siren Pack. That way it will only replace the firetruck one.
