JBINTX is correct, I had forgotten there's a connector for it to plug into on the positive battery terminal, thank you for the reminder.
However, now I am a bit confused. I might have missed something in one of the videos ... what is the entire path of that wire? I know it starts at the positive battery terminal, goes into the dash harness, and then to the body harness, but that that point, it seems like it need to go to both the BCM and to the power steering connector at the fuse box. Which does it go to first?
