I haven't gotten off my hiney to relocate mine yet, but it will be pretty straightforward to mount it on the steering column.
Not that it isn't really really easy to install the wheel, and hopefully Dusty gave you the pictures/tech stuff I documented, but if not, email me and I'll send you the install instructions for the TRD wheel.
I've driven with the TRD wheel for over a year. I haven't missed cruise control at all, truthfully. In fact, I've yanked the cruise box module under the hood and the cable that runs across the engine. Looks much cleaner, not that I'm into the "clean" thing.
