There's lots of products out there you can use to dress cable up and make it look good after your connections are protected.

Dielectric grease is your friend for connectors that are potentially exposed to weather. It keeps the water out, so no corrosion! I use fully insulated quick disconnects like these for the wiring. Squeeze in some dielectric grease, and you're good to go.
