That's the plug for the right hand side controls iirc, the alarm one is the same plug to look at only black. And further down the bike on the right side chassis spine than that white one.
You can use the redundant side of the black plug to make the jumper/bypass plug for the alarm.
Oh yes the left side controls has a black plug too but that's up at front of engine over cylinder 1, and should be clipped to a bracket. Don't want to mix them up
