2001 Volvo S80 Siren

Since I'm getting good info to fix things, may as well put you guys to the test.....as stated 2001 Volvo S80 T6. I bought it knowing there were some issues, but, heck, I have a hammer!!
The siren module which contains 3 coin batteries (don't even ask why) which corrode and eat the pc board of the module up. The module is located under the pax front wheel well. You have to remove the wheel, well cover to get to it. Don't know why they just didn't put it under the hood where you could service it.
When the siren goes, of course the alarm system goes, but it takes with it, the sun roof, overhead lighting, automatic mirror, door locking system, and things I haven't found yet.
Wondering if anyone has had experience with this. I would like to bypass the siren, but want all the other stuff to work. I don't need the siren.
Thanks in advance for any help.

chandler,

Volvo does it purposely. The module is located where it is for security purposes. Under the hood leaves it vulnerable to defeat, even while ringing. Many thieves have a large “Apple Sack” (if you catch my drift), and continue to steal a car even while the alarm is ringing. If the module was simply under the hood, in plain sight, once the hood was opened, all the thief would have to do is smash it with a hammer to silence it. The items you mentioned (sun roof, overhead lighting, automatic mirror, door locking system) and more run through the module. Again Volvo does this purposely so the owner is deterred from simply disconnecting the alarm module. You have to leave the module in tact so that the mentioned items (and more) continue to work. You can silence the alarm portion (piezo tweeter) of the module by cutting the black ground lead feeding it.

Well alrighty then. Yeah, I have the Matthews download. That is probably the best step by step instructions for anything I have had in a long time. Now if I could just grab some time to do it. The module runs a little under $200, and I don't mind replacing it, but since it is so small, and subject to the battery corrosion, do you think finding a place in the already cramped hood area would be a viable location for it? Even if someone tried to steal it, I'm not going to try and stop them. That's what I have insurance for, and I might hurt them, badly.
Thanks for the response. I'll let you know how it goes.

If you really want to trick a burglar, pull a door speaker out and mount it inside the door. Not sure how hard a job it would be to wire it that way though.

You can put the module anywhere you want. Just a matter of extending the wire connector to wherever you put it,
