Unusual.....I thought you would of bought your own leds and wanted to know ow to install em. Thats one weird led setup.... Open up your xbox and get your controller ports out an take off the metal casing on top. Hot glue two leds in on each side of the ports (where you can see through to the other side). Buy a
Y-Splitter Molex cable thing, and hook it up
