It is hard to tell from the picture but it looks to me like the holes (10-15, 35, 38) for the wheel sensor contacts are populated. Compare them with 8, 16, 17, and 20 in the top row and 41, 45, and 47 in the middle row which are not used.

Again, the WDS reveals all. In all the wheel speed sensors, new and old, pin 1 is the speed sensor output and pin 2 is the voltage supply for the sensor:
