That doesnt seem too hard to fix. The T817 is just a 3 phase Tformer that you can use a schematic from the manual to check wiring (better verify). That board your missing I believe that is just the overload board which you could source off ebay for a couple of dimes. The #13 plug is that the 4th axis plug for the socket #13? If so jsut ignore it. And the wires....well the only thing I think you got screwed on were the wires.
