If you are looking for the TSB for your S320, you may not find it.
It turns out the TSB that I posted is not for the engine wiring harness. It's for a wiring harness that I guess is under the floor mat.
This surely wasn't an issue in the W140's.
MB still to this day has never admitted there was a problem with the wiring harnesses from '93-'95, even though some dealers have replaced them under a "goodwill" warranty.
