Hello everyone,

I'm working on upgrading my Audi A6 C6 4F5 headlights from halogen to Bi-Xenon. I have an aftermarket adapter that converts the halogen connector to fit the Xenon headlights. This adapter comes with four additional wires (as you can see on the picture) that I need to connect to the "onboard supply unit" (J519), but I'm not sure where to connect them.

The wires are supposed to enable the high beam and other functions, but I don't know their specific purposes or which pins they should be connected to on the J519 unit. Could anyone help me where should I connect them? Thank you so much for any help !
