Been trying to fit a LED RNSE to my 2007 A4 B7 and having removed my old Concert II+ and being confirmed that I need to switch pins for the K Line. However, I seem to have a prob as there was nothing plugged into the B Block of the old unit and nothing in the harness. Is this normal as not seen anyone else mention this through searches.
Am I just looking in the wrong place or will I have to purchase a 12 pin plug and just switch over the C7 pin into the empty B5 pin of new plug and plug that into B block of the RNSE?
