[E34 530]

Hello guys. I just bought this alarm off of ebay not expecting to win it.

I now need the siren for the alarm. I found this siren on ebay for an e38.

Will this siren work?? I also like hou my uncles e38 siren sounds compared to other models. What do you guys think?? -Andrew

update:
I was abe to get the system working. i figured out that the car came pre-wired with an OBC "siren." The horn sounds, the lights flash, the only thing I cannoty get to work is the actual doors locking/unlocking. Any suggestions??
