This Logic Datum II tonearm came with a recently acquired Mantra TT.

Its lost a cartridge tag but also looks to have the earth wire detached and I don't know why its hanging out the front and where it should need to be reattached / resoldered?

Its in very good nick so worth sorting. any ideas on where the (black) wire should be reattached?
