I should of thought to take a look at the oem parts. I am not sure if this is what you were saying but part 1 is just the cap and part 2 is the light housing. Now if the light housing is seperate from the rest of the handle strip. and it is the same size as the ones on other models then there is no modification needed. This weekend i will try to remove the housing and compare it to a 3 series. Also i got a reply from a Chinese ebay seller with the measurements for the camera. If i do manage to remove the housing, i will post measurements and differences between it and the 3 series. Lastly if anyone could tell me or send me the TIS files for a rear camera and video module install so i do not have to go to a dealer, i would greatly appreciate that.
