I tried to hard wire the V1 in my dads new X5, but could not locate a switched 12v. I was using this DIY..

And could not find that bundle. My dads car does not have homelink which was where I pulled the switched 12v for my hard wire in my e46. Here are some pictures of what I could see, and it is quite obvious that the bundle running along the very front of the windshield is quite a bit smaller. I noticed the sunroof is only active when the car is on, so there has to be a switched 12v somewhere up there! I just couldn't find it.
