Internal wavebrid / need help in Basic Electronics

[Crosz]

Hey guys i´m almost done with my 4x Wavebird internal mod.

What i want to do:
-Put 4x Wavebird reciver into the Gameboy Adapter of the Gamecube, (Almost done)
-build a 22 Pin Connector into the GC and the Gameboy Adapter to connect the GC with the Recivers (Done)







What my Problem is..:
The reciver needs 4 wires to connect with the GC to make it work, but i want to use the LED of the Reciver so i need 2 wires more.
So i need 6 pins/each reciver (24) but i got only 22 Pins on my connector.

My question :
Sorry if this is a totally retarded question for people who are experianced in electronics...

Can i connect the purple wire from the reciver (Ground, goes actually to one of the 4 big Pins at the PCB) anywhere into the Gameboy adapter?
So can i use "Ground" of the Gameboy adapter??

The Basics for this mod i took from this Side:

Is it understandable what i´m asking for? :/

[megalomaniac]

yes...you can use ground from the gameboy player...

Oh man good news.. the following question for me is:

Where is "Ground" on the Gameboy Player?

Is it a special Pin or the metalshield ?

Do i connect the 4 Cables to those Pins on the Pic?
