No, no link to the headlight switch.
The command flow is as so:
>The stalk is connected to the steering wheel ECU
>A CAN message is broadcast when the stalk is pressed
>Message read by J519 09-Cent. Elect. via CAN
>Cent. Elect. sends a LIN command to J400 Control Module for Wiper Motor
>The wiper motor module sends +12v to the pump, fluid is sprayed, from the pump the cable goes to earth point, lower part of right A-pillar
