Step 4 Heat shrink tubing

Cut a very small "sock" of heat shrink tubing, and place it over the copper wire. Heat to shrink, using a cigarette lighter, a heat gun, or the edge of your soldering iron.

I didn't have heat shrink tubing, so I left that wire end exposed (but tinned) until I had soldered the wires back on and was ready to replace the cap, at which time I put hot glue around both wires. I think this has the added benefit of added strain relief too.
