Lego Nxt "Secrets": Light Sensor Music/Wand

Step 2 Build the shaft/wand [People doing Only the Required:Skip this step]

Stick the Various connectors in like Image 1, Then Put the Light Sensor on the two connectors sticking out from the side at the top, and then the NXT brick onto the Bottom two sticking out from the side at the bottom. Attach cable from light sensor to Port 3.

Please note that I messed up with the photos while rebuilding it, if you attach the NXT brick using the studs from Image 1, You will NEED to use a long cable, Image 2 uses a Medium cable.
