C2 Cruise Control wiring diagram

[KubaG66]

HI everyone,
Looking for a cruise control wiring diagram for Citroen c2 1.4 HDI (2006). I have Sedre downloaded on my computer but it seems not to be complete as there's no diagram of cc for C2 (there is one for C3 Pluriel, but I am not sure if ECU's are the same).
I retrofited cc in the car, telecoded cc both in injection ECU and BSI, checked both brake and clutch switches and cc still doesn't want to work. My last chances are either any of the calculators are faulty, or there's a problem in wiring. I need to know what pins at engine ECU and BSI should be connected to brake/clutch switches,
If anyone could help...? Not a big deal - it's a "town car" but I'd be happy to add one more feature to it.

The C2 and C3 platforms are virtually identical. The Pluriel is a little different but not as far as the cruise control is concerned.
I could not find any diesel variants of C2 OR C3 with cruise control in SEDRE!! Only petrol! And no "all CAN BUS" vehicles either.
The engine ECU is responsible for the actual CC. Only the brake and clutch switches are connected directly to the engine ECU. The switches near the steering wheel go through the COMMs unit then to the BSI then to the engine ECU over (in your case) the CAN BUS.

Thanks,
I will use the diagram I have then. I will publish the results of my investigation later - waiting for better weather to start with the multimeter
I believe it is clutch switch - ECU connection to blame. I can check the operation of brake switch in Lexia (seems to be OK), but there's no way to check if clutch switch is operational with my diagbox. Tried different lexia vesions and this cannot be read.
