Yes that is me. And nope, all those pics are lost somewhere on an old hard drive lol. But the steering wheel controls were pretty difficult because its such a tight space to fit an LED in. Reason it took me so long to do the whole thing was because of trial an error. I would solder them on, go check in the car to make sure they work. If they don't pull it apart and redo it.
If you don't want to mess with the steering controls yourself, you can buy premade sets from ZZP for like $60 or so which come with any color you want. That's probably what I would do if i ever did this again.
