I have an old Bosé system, AND need to make a 8 pin din to rca's AND 3.5 plug, if Any one do it? Someone knows the pin layout?

 

You will have to either get this from BOSE or probe it. Doesn’t appear to be a wiring standard for those connections. I found this but you will need to probe it because it may cause damage if this is different from your device.

At the very least confirm the power pin and ground using a meter

 

I'll check it, tks
