I found a guy on craigslist with a 1993 400sel, he is parting out so I asked him about the rear end, if it was a 2.82 with ASR ? he said he was not sure but he would check. So he e-mailed me, and said he was not sure if it had ASR and how could he check? I told him I think there should be two connections on there one for ABS and one for ASR. Is there any other way to check for ASR on the rear diff, its now out the car and in his shop!
