Nice car and tasteful mods. How is the rear camber after the X was lowered?
The FRM has to be coded correctly, nothing else. I didnt find you mention which tools you are using. If use ISTA it will get coded according to the car's original "Vehicle order", where this type of light dont exist. Also ISTA may not accept it at all because FRM3 may have never been installed in this model/range of VIN. Most probably you will need custom coding of the FRM to make it work correctly.
