A very helpful diagram overall and it has provided about 90% of the info I need, so thank you.
But there are pins which are not identified , although the notes on the diagram say "contacts which are not identified are vacant/unassigned". My van is a T6 highline and the wiring loom has pins in use which are not shown on the diagram. If there is any possibility of an update , this would be great and much appreciated. For example, USB +5V and earth are shown, but I cannot find the USB data pins. Secondly my van has a second USB socket, and these pins are not identified on this diagram (unless all 4 USB data pins are connector 4? - these could be other forms of data as well as USB)
