I hear you on the 'what should be in there' argument. My local MB parts store (A better wrench in Chapel Hill NC) looks this up and they too said it shows one with a strip fuse. That's not what's in it. I'm going to do some voltage testing tonight to determine what is and isn't working. I'll also get a p/n off of the old one to cross and see what it is made for. I've had the car for 18 months with no problems in this department so whatever is in there was working, but sure as hell isn't now.
