The second weft pass detailed above is shown on this chart. The black dots mark the black warps that are selected to float. All the rows that are marked with red dots on the chart involve the same sequence of moves, that is, selecting the black warps from shed 1 that are going to float, adding them all to the warps in shed 2 and passing the weft from left to right. I have only marked the warps with black dots for the first couple of weft passes. It is up to you to mark the others!
