Radio connections original Gamma CC active system

Hello!

Does anyone please have an overview of which original cable colors belong to the Radio gamma CC Active System? (Plugs 2 and 3 are clear to me, only plug 1 does not belong to the power supply, mass, GAlA etc. what is and where to connect). It's what happens when everything's been made up...

Colors are:
Red/blue - permanent increase
Brown - mass
2x white
Grey/brown
Grey/black
Blue/white gala?


Greetings.
Christoph
