Thanks for the response. I have two questions. First off, where is this amplifier in the engine compartment on a W126? The second is whether the 6 cylinder W126 diesel has the same amplifier or not? I have a wiring manual for my car and see nothing denoted as an amplifier for the tach.

If I can locate it in my 300SDL, then it might help me look for or locate it on the 300TD.

Frank
