Any body has pics of the wiring install. I have a 2009 x5 which i will only use with the small 4 pins connector. Connector installation seems pretty easy as, 1 connectore links to the electric hitch. The other one to the Cpu but, where its seems more complicated is, there is 5-6 individual wires to connect. Any body has pics of this. It seems as the red and brown must be connected but, what about the others ? They also supply me a small black box wich, i remember to have seen on my previous x3 but, no indication on the installation sheets where thisbox connect. Anybody can help me ?
