Bi-Xenon headlight circuit diagram needed for retrofit

Can someone post the headlight circuit diagram? I switched out my halogen headlights for Bi-xenon headlights on my '05 330i. I already installed the front and rear level sensors and I made my own wiring harness to connect the headlights to the LCM. This is the only information I could find on how to wire the headlights:

PIN 39 Q22 LEFT headlight actuator/motor
PIN 40 Q11 LEFT headlight actuator/motor
PIN 41 Q12 LEFT headlight actuator/motor
PIN 42 Q21 LEFT headlight actuator/motor

PIN 51 Q22 RIGHT headlight actuator/motor
PIN 52 Q11 RIGHT headlight actuator/motor
PIN 53 Q12 RIGHT headlight actuator/motor
PIN 54 Q21 RIGHT headlight actuator/motor

The connectors that I have are labeled 1, 2, 3, and 4. I'm not sure what order to connect the wires into the LCM. Any help would be appreciated!
