docfar, That is a fine tonearm. It comes either hard wired or with a 5 pin DIN connector which is round and both channels head into it. It is keyed usually slides into a barrel and there may be a set screw that locks it in.
If it is hard wired you are in trouble unless you are good with a soldering iron. At least the arm wand wiring is OK. You will have to take the junction box apart, cut the last 1/2 inch off the cables, trim them and solder the ends to the terminals inside which you will have to clear first. I would have no trouble doing it but there may be a tech near you also.
If it is a DIN plug you will have to remove the plug from the barrel and buy a new cable. There are a bunch on the market.
