Diving deeper into my Spidy, repinning the edge connectors and it seems my A1J6 is missing wires to pin 13, 14, 15 and 16 which the manual labels as "Return" lines. Can anyone point me into what these are for? Would greatly help me track back where they are supposed to go and also what happens since they arn't connected for some reason (I don't even see the empty wires in the back box at the moment).
Many thanks
