Thanks Fezzik. Very useful step by step tutorial. I just finished my BV install and going to be doing radar/laser install possibly next weekend. Your post definitely saved me some time. I do have one question:
Your suggested yellow line for wiring runs basically along the side curtain airbag, no? Are there any concerns with the wires interfering with airbag deployment, and/or potentially damage the airbag while fishing the wires through? I don't have a pano, and I found a nice "channel" as shown by red dotted line below.
.
One more piece of useful info, the unswitched 12V under the microphone grill uses Fuse 50 (5A used for car siren).
