I have cruise on my Direct-Fit column, but it's a typical add-on that either slips over, or replaces the turn signal stalk. Works well, but I didn't install it so don't remember all the details.
Because it's not stock to the Ididit column, the wires run down the outside and get clamped underneath to stay fairly well out of sight. Not as clean as if they were run through the inside of course, but still pretty good.
What are you going to use as an interface? Aren't the controls in the steering wheel normally? You going to try to wire them to an alternate control mechanism like on the stalk?
As much as I thought I preferred the Ford design, putting them on the steering wheel, after many years of constant use of cruise-controls of different brands, I actually ended up preferring the good old GM style on the turn-signal stalk after all.
