I have looked at the retrofit kit and for my build year 05, i will need to get kit 65 41 0 445 684, which will involve splicing of wires.
I also have the install pdf from BMW
Does anyone have some pictures of the exact wires that need to be cut ?
From searching on the web I think the wires are under the kick plates on either side of the front doors
The pdf mentions it, but as always, a picture is better
