I have a old lady (2008 dalara), and i can see it have sensor on each wheel, does anyone know if it is "connected" so i can get the data from the OBD ?

They are used, if you would install the "ABS" Option, I guess.

Ecu should have speed input, but ecu from old x-bow is not configured to generic OBD output. Either enable it in the ecu (some chiptuner can do it) or you need to use the VW protocol to read information from ecu. Maybe also pins in ecu-connector are not connected in the standard way...

you need to connect the pins corectly, I guess.
