Default Horribly noisy auxiliary coolant pump (FL S8)!

Sadly today my pump decided to go into noisy mode, with a horrible high-pitched throbbing note that just got louder and louder.
So I thought - I know how to deal with that at journeys end, having done so before. Wrong.

The wiring for the facelift D2 is different and the connector next to the pump that can just be quickly disconnected to silence it isn't there!

On PF there are two similar connectors (different colour coding) one of which is for the pump. On my FL there's only one connector visible, nicely held in a little plastic clip too! But it's not the one for the pump.

I can't believe the unit that the pump is part of is any different between PF and FL, so I'm hoping the connector is squirelled away somewhere not quite as obvious, but accessible. Does anyone know where and how to get at it?

Or is there a relay that controls it (logic says there must be from the way it doesn't kick in immediately on starting) and can that just be pulled? Again, anyone know if/where that is and whether it controls anything else?

The noise did reduce slightly on the return journey, but it's still highly irritating. After about 5 hours of it today I'm climbing walls!
