The ECU sits right behind that with a harness attached. The harness on mine goes off towards the center of the car. My unit was sitting behind an aluminum bracket. The Bosch number was easily visible and the MB part number was patially obscured by the bracket. I would provide a picture of mine, but I am getting some body work done and the car won't be avail till tomorrow or Saturday. Thanks, Mark

LOL, yes...
Does this help? Forground right is top of battery.... dunno what the cast aluminum housing is above that.... but you can see the corner of the Klima relay in the top right.

Merkey,
I am impressed. To get a visible image of that tag on film was quite a feat. Unfortunately, I now see the folly of my ways. My assumption that we have similar cars with similar components is quite the leap. Your picture might as well be of a Ferrari F430 Spider. I knew that the '88 and '90 300te had some differences, but I had no idea it related to every component under the hood.  I won't be getting my car back for a few more days, but when I do, I am going to trace every wire if I have to to find the gremlin  that is preventing me from getting accurate duty cycle readings. My suspicion is still that the ECU is faulty, but I want to fully eliminate the wiring first.

Duty cycle readings incorrect
Ok so I am in pure hell. I have a very nice 1986 W201 2.3-16 and I decided after all the reading I did about duty cycle and CO setting to check mine out. SHe smelled a bit rich so I thought, hey, I'll do it the right way and buy the meter and test it. WRONG!
I have read everything on the forum about setting the CO by duty cycle and by EHA. I added it to what I already have learned and already knew and put it all together and still have no explaination at to why I cant get the readings correct. I cant even get the 70% or 85% to read indicating a Federal or California car with ingition on and engine off. When I do this simple test at the X11 diag connector on the drivers fender well, I used both the 2-3 pin setup and the 3-2 pin test. Red and black leads in 2-3 and then in 3-2 and neither shows 70 or 85 percent. Red in 3 and black in 2 shows 50.6% plain as day al day. Red in 2 and black in 3 shows 49.8 all day long. Using a different ground instead of the 2 pin gives the same results no matter what. I have a spare ECU computer, correct part and numbers for the car, an exact duplicate and a working pull. I swapped it and is shows the exact same values for duty cycle. If some one wants to tell me I have two bad ECUs that went bad wit the exact same resistance, go ahead, but I think the ECU is good. Can anyone clear this up? When I start the car , the readings all go way in to the 90's and fluctuate from the initail 50% after the warmup period is over. The o2 sensor is new and the eha is relatively new and does not seem to leak. Other than the car exhaust smelling a bit rich, the car runs great. maybe the idle is a bit low, instead of 900-950 as I think the manual states, it might be in the 750-850 range. But, no stalling, easy starts col and hot, no overheating, ac works fine, etc....just screwy readings that match nothing I can read or hear from anyone else.

crhenkel, what is the build date of your car?
CD says 4/86 is the begining of fault recognition.
