Dx7 And Grey Matter Response E! Card, Need to know the wiring between the two Options

[abcdaniel]

Bought a DX7 with an E! card. Only problem is that the E! card isn't installed, and the wires are cut. What I need to figure out is how to connect the wires from the E! card to the DX7. There are two wires in the manual, one red and one black, to be soldered, but I don't know neither from where, nor to where.

If anyone can help me, it will be greatly appreciated. Need either a photo of the connections, both on the E! card and the DX7 or some detailed schematics. If anyone could open up his or her DX7? Weeeeee!
