Cal 1430 case connector, where does it go?

Hello all you watch enthusiasts. Recently bought a 1430 project off fleasbay and having inspected what looked like a reasonable project found that there had been a certain amount of work done on it. Bottom line is that a few parts had been badly damaged (coil and shield) and the odd screw missing. That however is the joy of buying online. The Forest Gump box of chocolates scenario. Anyway the point of the post is that the Case connector fell out from somewhere in the movement. It had been broken in half and I don't know where it goes. Can anyone give me a clue/ schematic to show where it goes . The part number from a later parts list would be 20.780.00 or perhaps 1430-9080 .

thanks Chris
