we just tried the pixels, it does look like they are green and they used to be white and the labels are different
but they do work (we just tested them OK)
please upload the strandtest example from the WS2801 library
connect 5V to the pixels and then the YELLOW wire to digital 4 and GREEN to digital 3
don't cut any pixels!
don't run any adalight code!
use the 'end' that has the socket 'female' connector - you should be able to just plug some wires in
