Hi Tony,
I have just answered your PM and attached this from the BV6 manual: (I think you already have the 8-pin connection list?)
But have you considered buying a purpose built lead from here? https://shop.oneremote.dk/shop/69053-oneremote/4172-tv-stand-converter-snut/
I know from experience that the BV10-32 will fit onto the BV7-32 stand, but there is a problem with the geometry of the stand components versus the Centre of Gravity of the BV10-32.
Here’s a side view of the BV7 stand:
And a side view of the proper BV10-32 stand:
When you put a BV10 on the BV7 stand, the TV drops all the way downwards and tilts fully upwards due to the orientation of the two (near parallel) cross members. The different orientation/geometry of the BV10 stand hold the TV (stops it dropping) let allows you to tilt the screen up or down. The entire mechanism appears stiffer and more controllable.
When I temporarily used a BV7 stand for my BV10-32, I wedged a rectangular piece of rubber in the gap between the supports to stop the TV dropping downwards.
