Thanks but I can't find it. Maybe you need to be a premier member to get access?

Anyway, this I found this website:

WDS BMW Wiring Diagram System - X5 E53

It has wiring diagram and lots of other useful stuff. Found the pinout on the connector to the ABS module.

For those interested:

Wheel speed sensors are:

13,29 LR
14,31 RR
28,12 LF
15,16 RF
