2002 C5 2.0 L EW10I4. With manual transmission I put the stalk and the lexia is recognized him. I bought a red brake pedal switch. 1. I have no wires for connection red brake switch. 2. I can't find cruise control activation in Lexia. No cruise control activation in BSI or ECU. I also have read that first must activate that option in Pre-Delivery Inspection, but "Function not supported for this vehicle". What should I do?
