One note on "Butt connectors".

If you use butt connectors, I recommend the 3M connectors that have "heat-shrink" built in. It's another step and requires a "heat gun" but they are far less likely to corrode or vibrate lose.

Solder and heat-shrink are BY FAR superior and still requires a "heat gun". I would stay away from electrical tape. In fact, I would prefer wire nuts to electrical tape and I don't like either one.
