I've resorted to using several hemostats to pull everything else out of the way, and pieces of thin tile or whatever I had laying about to clear a path and minimize chance of collateral damage.

Then deoxit and pre flux switch terminal, and use thinnest pencil you have with a dimmer to get just enough heat to tack on newly tinned wire (if not enough room to wrap properly.)

Your hands and eyes are younger than mine, so you should not have a problem.
