Crimping terminals onto cables requires heavy duty crimping tools. The most basic, and cost effective crimper is the hammer crimper. This is what I used.
You can also buy a hydraulic crimping tool. This tool may provide more consistent results, but it is more expensive. It’s also not as much fun. The hammer crimper lets you get vent your super hero frustrations.
