ECU road speed sensor?
Discussion
I took my '95 400 for a spin earlier with Rovergauge connected up for a bit of data logging.
The speedo on the car works, although typically over reads by 10 MPH. The speed on Rovergauge remains a consistent 0 MPH, regardless of actual road speed.
It is obviously information that the ECU would benefit from receiving, as otherwise the input wouldn't be allocated, although the car does drive perfectly.
So, does the ECU share the same speed sensor as the cars speedo via some type of splitter or is there a separate sender located elsewhere (I've done a bit of searching and found some info relating to an LT77 gearbox/early Chim/Griff, but mine is a late '95, with a T5)

but they are rather crudely assembled so may be just a dry solder joint
