Hi, fairly new here, trying to gather some info. I have had some ignition module problems on my 2001 (w208) clk 200. I am going to have to replace it, but I was wondering, is there any special circuitry in there or does it literally act as a big switch. If so I would really like to bypass the whole thing and wire everything into three switches. One for the first position of the key, one for the second, and then one for the starter. So what I'm asking is, can it be done, a wireing diagram as for what wires do what, please if you can help out, do be specific, replays like 'circuit p30' don't really help me. Finally, not to sound arrogant, but I just want to know if it can be done, I don't want replays like 'if it was better that way, MB would have done it that way in the first place'
