What are these wire connectors and where can I get replacements?
The first (2) photo's show a Female &quot;Bullet&quot; crimp connector. The third shows a Female &quot;Spade&quot; connector. Both are available on Amazon.
They are sized according to wire gauge; that is the color coded crimp connector's only accommodate certain wire diameter's.
You may want to consider that a new bullet connector may not fit securely enough to stay in place. You may want to consider soldering the wire at the break and wrapping it with shrink tube. I've made repairs similar to your's and had to reduce the opening of the new bullet to keep it secure.
