The control of the cruise - engine speed and power is controlled by the engine ECU.. If the ECU doesn't have the software/maps, it wouldn't be possible to implement cruise control. The BSI will also need to be programmed to include the cruise option. It will be interesting to hear how it goes and if the software is in place. I don't see that it would be impossible, but more along the lines of uneconomical.

Q1: Please can anyone with a real c3 cruise control check for me how I should wire them up?
Unfortunately I don't have a new shape C3 to compare wiring.

Q2: Does anybody know what it is for?
You could test to see if its the brake switch, there will be a change in resistance to earth or between pins when the brake pedal is depressed. You will get a resistance change even with the battery disconnected if its a traditional switch.
You will need
diagbox/lexia (here) to access the BSI to update cruise 'present' status.
