I really like the idea of mounting it under/behind the lic plate, easy access and out of site, this summer I am going to study that spot , I cant stand looking at them ugly plug in things mounted in the fog light holes or anywhere in the front bumper area,
I ran a short exstension cord to mine and its tucked in just behind the fog light hole and zip tied to stay, I can grab it real easy and pull it out and plug it in when needed without opening the hood.
