Hi. I’m renovating my hallway and want to replace the old and dirty phone socket. I believe this is a master (from outside with extension to other room). The socket is currently in two parts. One part contains white and orange wires for A and B connections. The second part contains thin blue and blue/white wires going to 2 and 5. I purchase an MK phone master socket but in only has 1-6 connections. So what goes where or do I need a different socket? Thanks
You need a different socket.
