Wiring diagram for xenons - 2007 mk1 facelift C5

[Harlequin]

thank you sir.

so , IMO, I need 7715 and 6606 and there's an extra loom runes from PSF1 (9 and 10) to each light and a loom run from the bsi to 7715 (assuming thats the suspension pump) and 6606 is the light ecu.

is 78-- related to tyre sensors (I know it says esp)?

most looks at my unprofessional glance to be very similar; ofc mine doesn't have tyre pressure sensors.

What's the end of this story?

In my setup, I don't have only the 6606 Directional Headlamps ECU

having experience converting my old '86 BMW from ECU Motronic 1.0 to 1.3 from a '94 7 series, looking at the diagrams it's doable.
Need to wait for the summer and find the missing ecu+connector, and the diagram for my car, and will try it.
