It won't screw up your X5, there is an LCM connection to connect the trailer brake controller to.
I do recommend that you use the factory hitch, and the factory wiring connection. Any cutting that may be required is to the lower trim pieces, and not to the structure.

Thanks JCL... I didn't think it was that cheap. If so, then it's a no brainer. But from the searching I did, the electric controller install looks to be harder than the hitch install. I did the hitch install myself and I was the one that contributed most of the pics into the forum post #9 here

What's an LCM connection? From the searching I did, the electric brake controller seems to be a bit more involved...scares me to to fiddle with the electrics and it scares me even more to pay someone else to screw it up for me ...
