the recall for "wiring harness" on the w124's is not the main engine wiring harness which is the problem being referred to on this thread. there has never been a recall on them and MB has never acknowledged that there is a problem.
i compiled all those nhtsa reports into a pdf and uploaded it in one of the threads on this same subject. you should be able to find it with a simple search.
