Gear position switch

I have a '13 Touring and it can't seen to give me a green light for neutral. As a result, everytime I put the stand down, the engine shuts off. Before I remove the little cover plate on the switch housing, is there any cautions or issues I should be aware of? Anyone have pics of what I might be getting myself into. I don't want to f*** it up since I live 240 miles from the nearest dealer service!!
I've read that a good cleaning of the contacts might help before I go to the expense of buying a new switch. Thanks for the help!!

What's your engine number?

The gear position sensor is on left lower back of engine. I think some early ones had a spring loaded ball bearing that could come out. But if back off bolts slowly won't be a problem. Clean it good and reinstall
