desktopper keyboard connection

[TXG/MNX]

Hello,

 

I lost my notes while moving. Can anyone tell me the correct connection of the separate keyboard with a desktopper case.

 

There are 4 colors.

 

Colors black is connected to the metal case as ground

 

But I need the pins for the connector that has blue/red/white

 

If someone has this info please share.
