1994 S500L W140 Immobiliser bypass ( sorry to ask a age old question )

Two great links from Grober

These cars were the last gasp of pre-Canbus "ordinary" electronics where the cars were loaded with individual modules, each with a loom, and the interconnections varied from car to car.

Hell on earth to diagnose as every one is different, unless you have access to a wiring diagram showing where connections are made. Dealers have this

Of course this car no doubt has Canbus as well, just to raise the bar a little higher
