Had to go back for rewire
Hey, this happened a while ago, but I wanted to share the info. I had my mechanics follow prior instructions in either this or another thread, so they tapped into power just beneath the shift knob. The problem was that the light would stay on for 20-30 min after I shut off the car, draining the battery. I had to go back, and they instead went behind the dash and used an orange/red wire (58G) behind the CIC radio. It now shuts off when I turn off the car, saving my battery from drain. Not sure if I'm making sense, as I jotted down quick notes after they made the switch, and I didn't completely understand the electrical details. I have iDrive if that makes a difference.
