e30ftw 396 Report post Posted September 20, 2015 I am looking for the section of loom that sits ontop of the valve cover on the exhaust side of the coil packs. I either need to find the correct part number if someone has it, or the loom itself if someone by any chance has one... This part of the loom is where the O2 sensors for the S54 come up to the valve cover and plug into. I think it also has reverse light wiring on a manual and maybe integrated with more on an SMG? Again, I can't find anything worth while. Here is a picture from google when looking for "MN3 oxygen sensor harness" if anyone can help with one or the correct part number. I have tried Real OEM.
