Konk is right, per the diagram. However, when I installed my Billski taillight, and changed out my rear turns, I found the green stripe and brown wires were opposite, at least on MY bike. I had spliced into the running circuit to hook up my turns for extra running lights, and had to connect them to the other wire than what the diagram showed. Weird, but worked out that way for my '03 Spirit 750.
