In the thread you posted the OP moved a lot of wires from AHL module to LM2.
What about the connection between LM and the headlamps, will my wiring have all necessary wires to cover all 11 pins or will I also need to route new wire(s) to lamps themselves?

To summarize the info from the thread you posted:

at LM2:
5 -> insert pin from rear right lamp [from retrofit PDF]
20 -> move to 75
21 -> move to 76
25 -> move to 53 [from retrofit PDF]
37 -> take out -> ground
38 -> take out -> ground
40 -> move to 11 [from retrofit PDF]
58 -> move to 38
59 -> move to 37
62 -> insert pin from rear left lamp [from retrofit PDF]
76 -> take out -> insulate
71 -> insert PT CAN Low
72 -> insert PT CAN High

at headlamps:
connect wires according to LCI UPDATE.pdf (wire colors will not match exactly)

+ coding (with build date #0905), will give me working AHL and Angel Eyes (and working rears but that's not related)
Does that sound correct?

start with your car wiring first.

You have LM2. You already have Xenons.
You need to first wire up the Adaptive Feature.
you need a PT CAN High and Low signal. You need to swap the Pins around. Once you done all that.

You then code.

Then when you go to fit the LCI Headlights, you look at the PDF. The PDF is not telling how to retrofit LCI Adaptive headlights, on a car without Adaptive Xenons. It is assuming you have adaptive lights prior. And Bi Xenons Prior to fitting.

Then you follow the PDF. The LCI headlights only have one connector. The Pre Lci have 2. One for the headlights and one for the stepper motor. Because it is showing you where to pin them. So do this step last, or later. Do all the necessary work for the LM2 first.

Your posts clarified a lot. Once again thanks for that. Just one more thing:

For the LM2 part, do I only need part 61138369696 (the small pin) or anything else? What about the grounding connector?

edit: also why do I need about 4m of cable for grounding if the grounding point is close to the LM?

61130005201 Part No.

As for the pin 8 and the power/CAN wires I'm pretty sure I'll find something fitting in my local electronics store, the prices for these tiny contacts at the dealership are insane.

By the way, after making all these changes to LM2 while keeping my OEM lamps on for now won't fry anything right?

When I go to the dealership to get the pins w/cables I'll have a look at the BMW spade connectors and compare them with the typical ones. If they look/fit different, I'll just get the OEMs.
