As I previously mentioned, for over canbus, a program must be installed in such a way that I described in the first page of this topic.
Besides, I found below picture yesterday showing a plug coming out of the canbus decoder. If you insert the plug with yellow and white wires in your above picture into the hole seen in the below picture and download the program for "raise" or whatever brand canbus decoder, it might work. I will try the same on this weekend...
