If you have the tools and the skill, I would recommend using shrink tubing and soldering the connections back together. Soldering wires assures a good mechanical and electrical path from wire to wire, and shrink tubing keeps the water out of the wires and the connection. Crimp style fittings (butt connections) work well enough, but usually won't protect from the elements.
You can search youtube for videos on how to solder good electrical joints. It takes a little practice and a small investment in tools, but it will make things more reliable for your bike.
I'm glad you figured it out! That's part of the fun of these bikes. Sure it's frustrating working out electrical problems, but patience, a good schematic, and one or two adult beverages seem to help.
