Hi,
Does anyone have the harness wiring diagram of the car S420 1994? Would you please, post or email this to dinh_hai_tran@yahoo.com. I have a very strange problem as I posted earlier on the auxilliary fan on all the time. After I checked the new engine harness which new part number is: 140 540 1132 on the tag and the part number printed on the harness is 000 545 4881. I called MB dealer, the person who answer the phone said the earlier part number (000 ...) is not on his computer anymore. But the point is that... the pin out new part number (140 ...) is not the same as the old one. I traced from old part number from AC temperature sensor to the computer go to pin number 6 (brown) and 7 (blue) while the new harness go to pin 5 (brown) and 31 (red). This makes my fan on all the time. I'm afraid that if I order another one, it will be just the same as the one I installed. Please, if you have this diagram, I would like to test pin to connector before I purchase.
Thank you very much,
