Well I just got lucky and got a 1987 190d Turbo (automatic trans) that has been sitting in an old mans barn for a few years(a steal at $500). I was driving it back and decided to open it on the hiway and got to about 95 mph and a warning light(I guess) came on. An square unmarked redlight second from the end on the right next to the glow plug light. The car has a lot of wear and tear and isnt in the best order right now so I figure it was a warning but it stayed on for another 100 miles until I shut it off. I downloaded all the manuals I can find and I cant find anything on it. Any help?

I also need a diagram for the fuse panel under the hood. Mine doesnt have the cover and I spent hours searching forums for one. I just need to know what fuse and what size fuse goes where.
