Wiring schematic for headlight washer pump

This is how I think it goes:
When you pull to squirt, (E44), the screen wash pump starts, and runs as long as you pull. When you pull to squirt, an intermittent wipe is also triggered, (E22). If the headlights are on, the headlight wash pump will also run, while the stalk, (E44), is held.
It would be good if anyone with working headlight washers could confirm this theory through.

The wires I suspect you are missing are the supply to the headlight washer pump, V5, ro/gn, the link to the light switch, E1, ge/sw, and a ground to the negative side of the pump.
The rest are there 🤞
