I'm about to install a center console complete with climate controls and foglight and hazard switches but I just want to make sure it'll work. I've seen some people already do this conversion but I can't seem to get any help from those people. Since the foglight buttons are different and have different connectors between the years, how do I install them in my 1999 a4? All parts I got were from a 2000 a4. Do I just splice the new style buttons with my old harnesses and just match up the colored wires? Some of the wires are different or have 1 more wire than the old style. Any help here?
