If it's just the wire from the cruise, you could run that without pulling the column. You'd need to run something like a piano wire down and tape the cruise wire to it and pull it up. I've done the entire wiring harness, but I had the column out. But there's no reason you can't do it with the column in. If you want the wire in the wire loom, you'll need to remove the four bolts that hold the loom to the column.
