This is what I ended up with, at least for now. I was concerned about folks other than me taking the tank cover off and not realizing something would be attached. Case in point, bike is back at dealer looking at possible frame replacement due to tail alignment concern and I think they took off most of the plastics. I'll look to redo, find permanent solution again later. May just need reminder to mechanic each time that there's wiring stuck underneath - not always easy to communicate directly with mechanic at this dealer currently however.
