A few weeks/months ago...I posted an idea of maybe making my own EGR plug to go along with the emulator. Currently, getting the MB plug by itself is not possible and buying the harness that has the plug is expensive. The last I checked it was closer to $41 plus tax.
I've started playing with AutoCAD this weekend and wanted to see if I could draft the plug. Here's the first version without pins, just the general shape to scale.
If anybody thinks that they can do better, pm me and I can send you the dwg file. Flossy, I can send you a STL file and you can print it to see if it fits before I add pins. Though I do have a 3D printer at my disposal, I no longer have the valve
