I am preparing myself for acc retrofit in my 2015 f10.
There are two things which I have no idea how to do:
1. Mounting acc bracket to front bumper. 
2. Wiring acc under the bonnet.

Does anybody have experience with above?

As I understand acc bracket is actually not using screws but some other funny method which I never came across myself. How did you guys handle it?

As to wiring, I don’t have a problem with how to get the wires from icm/kafas the to under the bonnet area, however after that, I am lost as there seems to be almost multiple chambers separated by connectors. 
One of the connector is x148*1b https://www.newtis.info/tisv2/a/en/f10-520d-lim/S0j1eiV, which I cannot locate myself. I am wondering if I need to disassemble completely front bumper and possibly right light? 


Any hands on experience and guidance really appreciated as I don’t want to screw it up.

Thanks
