Great web sight showing wiring diagrams on what appears to be all MBZ cars made from 1987 to 1997. Saw the web site on posting #126 of the current thread I did it! Keyless entry for your 124 made easy. Just retype in your year, model and select system wiring diagram from the drop down menus and you get wiring diagrams of all the various wiring systems of your car. I typed in the info for my 1992 300E and got all the wiring diagrams. WOW!!! It appears you can just type www.autolib.diakom.ru/car/mercedesbenz to start and go from there. Hope this is of help for anyone with electrical questions or gremlins.
