Go to escortradar.com. They have everything you need to mount your radar. You can get a wire tap and tap into the power on the back of your mirror or get a smart cord and run it around your windshield. They also have the mirror mounts. I'm getting a smart cord with Escort Live installed in my '15 on Tuesday at Best Buy. I'll just let them install it instead of me trying to deal with the heat and humidity.
