BXWinstaller

so, I feel like an idiot right now...with all the info on the web, I am having a hard time understanding exactly how to do this. I know that I'm supposed to move the yellow and black mute wire to the slot above it, but what am I supposed to do with the green wire....ground it? ground the mute wire? am I supposed to hook the mute up to anything? am I supposed to hook the green up to anything? any and all help is appreciated...
