I don't have any information to hand on the VDO unit I'm afraid. I'll have a look round later this evening.

Yes, the pin numbering on the Carav diagram is completely different from RAVE! However their positions are correct.
As I see it, if you use that 13 pin connector you will need to install conductors in the empty sockets for the following:

Pin 4 NSR speaker signal
Pin 7 K-bus
Pin 10 Steering wheel switches +ve
Pin 17 Steering wheel switches -ve

Any help?

Well just a bit! I’m pretty sure the VDO SWC wires on the green ISO plug should go to pins 10 & 17. I’ll try it when the kit arrives. I can’t see the Harmony needing the K-bus on pin 7 though as I now don’t think it’s had any K-bus input in the old car. As to your deduction re. Pin 4 (speaker), I don’t follow it. 🤨
