Dynaudio sub500

I need some information about the Dynaudio Sub500.
Inside connection cable broke, 6 wires from the front to the amplifier board.
The wires are soldered to the board, I think there have been a connector from the factory but now it's soldered. A few wires are loose from this board.
So I need to know which color wire goes where on the board.
It should be fit to the upper corner on the amplifier board.
Thanks in advance for your reply
