Trying to help my daughter sort out one of her guitars - one of the wires has come away from a volume control and requires soldering, but not sure where its come from and where to go. Have stripped it back cleanly and tried touching it to where I think it goes but no go.

Assistance appreciated :D  Red is the wire, green is where I suspect it needs to go.. am I right tho ? Get no feedback when touching that connection though....
