Can someone tell me which part in the steering wheel typically causes the SRS light to stay on? In looking at the parts catalog, I see part # 124 464 02 28 called a contact assembly for the SRS system. There is one of them in the steering wheel and the cost is about $100. The other possible part is part number 124 460 05 41. It is called a horn switch and there are two of them. Cost is about $15 each. The thing that confuses me is that the second part looks like it is the contact ring that others say needs to be replaced to correct the SRS light problem. I'm ordering some parts and would like to order the right part(s) the first time.

This is on my 560SL BTW.

Thanks.
