I am looking to add comfort access to my 2018 320i I have researched everything but can't find a clear answer, I have a comfort access key and now have a set of front driver and passenger side e90 handles because my model uses the e90 style door handles.

I know obviously I need a wiring harness that fits, possibly the exterior CA antenna that sits on the inside of the door, and possibly some coding. but the problem is I don't know for certain.

Can anyone guide me on this? does my current harness already have the connections and is it as simple as plug and play or do i need extra hardware?

Main question is it possible to use E90 CA door handles on an F30, and what do I need to make it work?
