I am attempting to custom install a reverse camera onto my non-iDrive E90 330i. I am using a Nexus 7 tablet as the display, but I am looking for a signal wire to wire to a relay to enable the capture device when the car is in reverse. I understand that the FRM (footwell module) controls all lighting in the car and thus the reverse lights. Does anyone know which pin/wire to tap into for the reverse lights? Otherwise, is there a better wire to tap into that only receives voltage when the car is in reverse?

I'm also wondering this. What did you end up doing?
