    The center (composite) image of the board is the key to the whole thing.

    I've enlarged it and added some notes around the edge:

    What's not obvious is which common terminal relates to which set of NO/NC contacts. I've added jumpers on the bottom as to what makes the most sense, but you'll need to verify by using a meter from the NC terminals to the common terminals on the bottom.
