wiring

Anyone have any idea as to how to wire auto levelers to standard headlights? I've fitted d2s projectors and I'm just trying to make it fully legal if at all possible. Any help would be appreciated.

Hi everyone, I need to get the complete engine wiring because I just found out that my EK9 was sold with an EK4 modified wiring and I'm having issues on getting it working right. So... It has to be an OBD2b wiring. Thanks.
