Perhaps you missed the point...
This is 0 for 3 at Benz authorized repair facilities on this problem. The regional rep told my servce manager (and I assume the service directors at the other stores, 100 miles away), to disregard any complaints about the harnesses unless the car was under 100k miles. So the question remains: how come the part is defective at one moment, and MB knows it, and magically is no longer defective but a wear item once it crosses 100k? The particular point is that the service reps are being directed to ignore these problems from New Jersey; these are not local decisions. The local service directors seem to be working harder to please MBNA than the customer. And that stinks.
