PMDG SIOC ADVICE

Hi
Recently bought the open cockpits MCP and trying to use it with my PMDG 747, now at present they have no sioc.ini file for the 747 but they do have one for the old PMDG 737 0n FS9, now using this sioc file the 747 seems to respond to commands i put in the MCP however it does not light the button switches on the mcp or chnage the digits from 00000, although they do chnage in my 747 FSX cockpit....i am not familiar with sioc programming..has anyonre any advice as to or where i can find help on a sioc.ini script i can add to get the button lights working and to make the digits move???


Thanks

Paul
