RE: SPEED SENSE WIRE
Sorry but I don't have the exact information that you require for a w140.
However a few tips that might help.
TMost MB's have multiple speed signals since they have ABS. One from each wheel although some models have a combined rear axle signal.
Each wheel sensor is fed through a connector not far from the sensor. This is a good point to pick up wiring colours.
MB have not been consistent in there use of colours for VSS. In general they seem to be White(ws) or Black(sw) with/without Yellow(ge) tracer.
Speed signals are usually routed direct to the ABS/ASRT/EPS module where they are used directly and subsequently transmitted via the CAN to other systems like A1 Instrument pack, Engine Management etc.
Hope this helps.
What are you trying to achieve?
