Walthers 90' turntable HO cornestone

[Beto]

Hi everyone, I need help to run the wires in my turnable. My layout is DCC and control is from NCE, my turntable come with DCC and the controler box is the blue one from walthers. I'm having a hard time installing it. The manual doesnt show the wire installation and I'm so frustated. I know fot those with eletronic knowledge it should be easy, but that's not my case. So, I just need to know where to plug the wires for the turntable into the layout. I know I need a separate power supply to power it. The also know that the wireless cable goes from the turntable to the control box. What I don't know is where the other 4 connections (ABCD) under the turntable go.  Any help would be appreciated. Thanks!
