Remember those little suckers get warm and like some kinda air movement/space around them. My brothers is mounted to his firewall on the inside of the car since the heater box is deleted, but it's got plenty of air space around it. Be careful mounting it in places where they can get directly blasted by road spray and such. Unless it's a newer unit all sealed up water finds a way in, I had one mounted to my fender and rain water migrated inside the backing plate and shorted the box out.
