Ok now sorted it
the cable has shielded white, shielded red, blue, white, black and yellow cores
The blue and white are not connected
the black is just a flying earth wire
pin 2 earth shields
pin 3 left channel - I assumed to be left channel and connected the white inner of the shielded cable
pin 5 right channel - I assumed to be right channel (right - red) and connected the red inner of the other shielded cable
pin 7 data - yellow
It does work as have tested on an Ouverture and the BG will activate via the remote play button
Have also produced a simple extension ie a 7 pin din female to 2 rca's to use with the BS4 which also works however under manual control ie finger on button
Now to give the vinyl a bending(not literally)
salut

NB thanks to all who have offered advice help with this project its taken a long time but eventually I have a achieved a system which works - unfortunately not as I wished - the BS is the master and tv the slave ideally I wanted it the other way round!
I always try to operate using/following the KISS principle -- Keep it simple stupid!
