I've never seen this symbol before but my wiring diagram is full of it. I also have searched for lists of symbols but it isn't among them. Does anybody know what is is? It is from my wiring diagram of a Yamaha RS 125. https://pasteboard.co/HX0dVKZ.jpg (the image was to large so i uploaded it to pasteboard so it wouldn't get compressed)
But this is the symbol in question.
