Hi Marc & Mark,
I saw Marc's question marks on the same couple of wires I need some clarification on. I haven't seen any resolution yet, and wonder if these wires should  be cut back to the connectors, left floating, or something else I am missing?
Below is my hookup chart. Is there anything that is incorrect, or needs adding?
