FWIW (and assuming memory serves), the additive pump lives in the additive tank. The additive 'injector' lurks somewhere near the lift pump/fuel sender unit, but has no wiring. :?
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

additive wiring makes sense, mine hasn't got a dpf they probably use the same loom and just leave it redundant, thanks for diagram.

No worries.

If you're really curious if you can give me some codes off the wires I can probably look them up.
