There are many ways to connect wires together or to a terminal. Soldering an crimping are the most common. Crimping is easy, fast and effective. Crimping crushes the wire around the connector and ensures a solid electrical connection.
When purchasing ring terminals, be sure to purchase those with heat shrink tubing. The heat shrink tubing will seal the wire, and provide a professional looking waterproof connection.
