Here's a photo of the buzzer we get on Australian bikes... which is damned annoying, I pulled mine out in the showroom on delivery It's at the back of the area under the main seat - the screw driver is sitting on it. It's only got a short cable. This should give you somewhere to start looking anyway. Mine's unplugged in this photo. I think the plug for it is just behind the plug to the left of the alarm itself (you can see it). Hope this helps. Boy that's an old photo, it's so clean under there Edit: It's just occurred to me that this might only have power when the side stand is down.
