2005 M3 Headlight Conversion

Hello, has any changed out factory Bi-xenon headlights to Spyder brand aftermarket headlights? I need some help on how to wire these please.

Trying to figure out what's the grouping of red, black and green wires on driver's side? They don't exist on passenger side. Also, the wiring harness on the driver's side is different from the passenger side which makes thins a bit confusing.

I have included two photos for reference. Thanks!

Check newtis.info for wiring diagrams. You should be able to get the purpose for all of the wires.
