I did a search for anyone else's posts, but obviously missed your excellent instructions. Your pictures are great and a great job on the write up, I wish I'd been clever enough to see it first.
My only other "tip" would be to make sure that the routing of the new cables does not interfere with the movement of the steering. I know you illustrated the wiring route very well, but I'd emphasis that a bit more as once it's on and tighten up, it would suck to re-do it or even worse, yank or pinch a cable.
Great job on the pictures. Thanks.
