?? Ok, I got one of these. Where does it go? It has a stick on pad on the back, but I can't imagine it staying anywhere on the outside of the car.

 

When I put mine on my last car, I drilled little holes in it and mounted in the grill with screws and washers. No way is it going to stick and stay. I used long brass colored screws with fairly big washers behind the grill. I had the 100K on for a while, but two weeks after putting on the 200K the engine went on me. So I'm not putting them on any more.
