Trakball cable connection

[Lohe]

Hello,

 

I need a bit of your help with my new cx80. The previous owner modded it for something it seems. There were traces cut and there were different cables for to bridge other traces. It seems to me there has been a new cable soldered to the seven pads on the cx80 pcb too. So that thing does not work anymore for my 2600. 

 

Now I need to know which pad on the pcb goes to what pin on the joystick connector it seems. The pads on the trakball pcb are marked with colour readings. First pad reads yellow, second orange and so on.

 

Would be fine if one can post help in this form:

pin 1 on the joystick connector to yellow

pin 4 to red
