Retrofitting the E39 M5 Active Servotronic Steering (on my M5 Wagon)

In today's video we retrofitted the Active Servotronic Steering on my E39 M5 S62 swapped 540it. Since we already installed the steering box, all that was needed for this installation was some wiring. I've attached a photo of the wiring diagram I used below, in case anyone is also performing this retrofit or is having troubles diagnosing their system. If you have any questions, feel free to reach out via email for more help!
