what is this wire for?

[mick!]

Hi guys .I have a wire coming out of my clocks which has been snipped off. (see pic) The only thing not working when i bought the bike (as a project)  was the speedo , the previous owner told me that was down to a sensor . if that being the case i assume the snipped wire could be from an alarm that has now been removed- I would be grateful if anyone could have a look and see if they have a similar single wire coming out of the clocks and if so tell me where it goes? my bike is on a 04 plate by the way..
