I am not familiar with our bike, but did you try to plug it into the right angle piece in front of your hand? I have one for a 996 if it's the same, it is a right angle unit, This may have just come unplugged, the plug-in would be underneath and not visable.
I believe it goes to the temperature sensor located on the inside of the headlight bucket. It should be just below the fuse box and towards the front of the bike.
