So my buddy brought me his Kawasaki Ninja service manual and asked me what this symbol is - sort of looks like part of a diode with a box instead of a line and is half shaded. I've tried looking it up but haven't had any luck and in the context of the diagram not a ton of things make sense. My best guess is they're connectors?
Also in the legend BK is black, Y is yellow and G is green.
Anybody know what these are?
