Hey. Anyone have any ideas how to code/wire "wake up 12V current" to additional light relay from BCM? I found couple of empty spots/pins from module, but problems is that i cannot locate those free pins from (09)central electrics list by using OBD11. Every other reserved pins for other lights etc. can be located from (09) Central electrics, but not the empty ones that i needed to code. Inductive can reader/relay could be an option but i mean, it costs over my light setup so no point to do that way either.
For example BCM connector C pin 42 is empty and it has an counterpart on the module, but it is not on the (09) central electrics list to code. Otherwise (Leuchte10SHUTTER LB 23) or Connector B pin 23 is reserved and can be found from the list.
Thanks in advance.

Edit: solved it out in another way. Found high beam excitation current from passenger side after all. (passenger side easier to disconnect). Yellow/black wire seems to be working for knowledge to others. May be good idea to use diode relay on your auxiliary headlight wiring harness.
