I was looking at a picture of an ignition switch for my 1984 190d on a parts store web site yesterday. It looks like you would just unplug the old, and plug in the new. Well, after reading some archive postings on the matter, I am a little bit concerned about me replacing it. I looked pretty good for a step-by-step guide in the archives, but didn't find anything but 190e's. I thought the ignition for a diesel would be just a little bit different. Any help pointing me to some instruction would be really appreciated. Merry Christmas.
