I have just bought the dual projector headlights for my 2015 three and I’m not 100% sure they will install, did you have any issues w/ wiring your projectors w/ the module and ballasts? these are my inputs and the headlight.
i think you need to cut and customize wires on a headlights, but i personally prefer to purchase adapters like this one and it will work fine.
