Input voltage to ABC pump

Anybody have any idea for the origination point for ABC pump voltage source ? 2001 S600 only fuses related to ABC are 9 & 46 per fuse chart. Zero volts at two pin connector.

The voltage for the valve on the pump is supplied from the ABC control module

The ABC pump to my knowledge only has inputs for the throttling valve. Is this what you are talking about?
There is also a pressure sensor involved.
