Answer
I would suggest finding a local garage or dealer that has a technical reference data system. Ask them how much they would charge to print you a copy of the diagram.  otherwise contact Renault on their toll free No. Also, the manufacturer of these "add on" systems usually have the diagrams and can  provide technical suport. Good Luck
