Let me elaborate on my first post. The wiring will up the "tower" extension but it is not long enough for me to run it through the spare tire mount as I wanted. However, I am trying to clear a 37" tire so maybe you will more slack if you have a smaller spare. As far as the back-up camera goes, it makes no sense to me to put the back up camera above the spare tire. The only feasible place, in my opinion is below it or inside the wheel of the spare.
