Got 3 pair MIB at a garage sale a while ago. Now I am ready to install, but there is no information/instructions in any of the boxes. Why do I have 5 binding posts, two of which are bridged together? Does anybody have any wiring diagrams, especially if there are some unique signalling options available. I don't have a problem connecting the 3-wire cable to the three posts, but what am i missing out on? many thanks to a wonderfully knowledgeable group of hi-railers!!!
