Wiring for four wheel traction control on S80

I'm just spread-sheeting out the pins used for the new loom and am slightly confused by the drawings, for the wheel speed sensors.

The main block are as below, (ignoring power and ground, which are 24 and 33 for all respectively:

Right Undriven 20
Left Driven 31
Right Driven 32

There is no "left undriven" listed in that group (as laid out on the ecu connector), but there is another input, simply listed as "Hall Effect Undriven Wheel Speed" over on pin 2, this time, using pin 9 for power and again, analogue ground at pin 33. Is this my "missing" Left Undriven input?

Thanks in advance!

Yes, that's correct.
