Hi, while using this thread as a guide I have just finished retrofitting the 2017 is200 f sport headlights on my 2015 is250 f sport. Everything works except the passenger side high beam and signal indicator. I did noticed that the passenger side harnesses didn’t use up nearly as much of the factory pins as the driver side did. Did i miss something? Thanks In advance!

you likely need to run a LIN bus wire from one headlamp to the other for the passenger headlamp to understand when it needs to turn on or off the High Beam.
