:lol: I'm sorry! I just couldn't resist! Honestly, I think folks run the wire out the third brake light, but I'm not sure. I'm sure someone that's done it will chime in on this.
I have 4 PIAA lights on my roof and have the wires run up the sides of the windshield. If you take a look at the weather stripping between the door and the windshield you will notice there is a lot of room in there. I have 2 wires running up both sides. Here are some pictures and there are more in my library.
