Looks like you have the right connections. Make sure the wires are firmly seated in the Arduino headers for a solid connection. They should resist a gentile tug.

I'm at work right now, so i can't test it. But i'm pretty sure the wires are firmly seated.
I've even tried to connect the wires to a breadboard, and connect the breadboard to the arduino with 155mm jumper wire, with the same result.

If you are sure they are seated firmly and you still get no data, contact [email protected] with a link to this thread for a replacement.

Well I have tried cutting some of the isolation of the wires and soldering the tips, so that I'm sure that the wires get all the way down and are seated firmly. And I have tried changing the sketch, to change the data pin, but there is still no luck.
