Trailor wiring colours
Can anyone help me on this. I have bought a new wiring trailor socket for my C320 Sport. Stupidly I didn't mark the wiring terminals. The colours 
are not the standard ones for the trailor connections for a 7 pin plug vis-a-vis 1. Yellow, 2 Blue, 3 White, 4 Green, 5 Brown, 6 Red, 7 Black. These are the colours in the trailor plug but the colours from the car are twin colour wires : - Red/Grey, Black/Grey, White, Green/Black, Brown/ Red/Black, Black/White. I have no idea which wire operates which light!
