On the new connectors you can take the body apart and remove the terminal end complete. Pull off the rubber seal and then pry the orange part out. After that its just use a small screw driver and you will be able to do the job neatly. You can also get the little white plugs to fill the void so it will still be water tight.
94c4 - Thanks for trying, but those brackets look like they are intended to mount the turn signals on a passing lamp mounting bracket. I don't intend to put passing lamps on my bike, so they wont work.
packrat - The forks on a night train are different from thos on a fat boy. The fat boy forks have a shroud that wraps around them. Attaching a clamp around a fork (like the night train) is just not possible.
What I think I'm going to try to do is remove the bolt that holds the shroud to the lower triple tree & remount the turn signal at that location, unless anyone has any better ideas?
