Hello I have a US spec R320 that I currently have here in Germany. I purchased a set of used leather seats for, 2006 r320 here in Germany in good working order. Both my old and new seats are heated, non memory, power adjusting with Airbag and active head restraint system. All connections appear identical. The only difference is there appears to be a relay box on the new set connected behind the three major connections, and two ambient light housing almost directly under the seat. When I plug it all in, I get only the heated seats to work, the seats power to move up n back the seats doesn't work and there is some electrical error messages lighting in the door window switches light up, park tropic lights blink, etc. when I unhook everything goes back to normal. The fuse charts are identical. Not sure how to fix it with, old seat photo.
