360 siren version

I just bought a new Ferrari siren for my 99 US 360. The new part is version 1.3 made in Hungary and the old part is version 1.1 made in Australia. I am wondering if the new part will function like the old part or if something was changed between versions that affects the functionality. If anybody knows I would appreciate it.

 

I installed the version 1.3 and it seems to work, my old one never worked so I am not 100% sure what functionality it is supposed to have. New question, has anybody replaced theirs with version 1.3 and if so, how long has it lasted?
