New Switchover Valves

  Mercedes Benz sent me 3 new switchover valves today. The new valves look nothing like the originals! It seems they were redesigned and now are multifunction valves. The valves in question control the EGR, Ignition retard and advance and air intake. The old ones looked like bells with a red, yellow and blue caps. The new valves are not colored at all. I need help in figuring out where the connections go on the new valves. Has anyone out there replaced theses valves with the new style?  Help!                      Old Style Switches are to the left numbered 9, 33, 55
