Well,
let's try without pictures.
The turntable has 6 connections, marked B,0,0,1,2,3, right?
And you have the control box handy with 5 cables: yellow, brown, grey, blue, green?
Then, control box's yellow and brown to yellow and brown of the transformer. Grey, blue and green, in that order, to 1,2,3 of the TT.
And both 0's connected to the brown (the turntable is usable also with two rail, so each rail has it's own connecteor). And last, the train power (wether it's digital or not) to the red of your 6021/IB, or the red of the transformer.
