Obviously I've lead a sheltered life, since I had not encountered a wire ferrules before.
Watching a YouTube video, they were saying you should NEVER tin the wire end before
inserting it into a screw type clamp. It will loosen up over time and cause problems with
the circuit. I had this happen to me, the fuel pump quit working until I found the
problem and re-tightened the connection. Additional to that, if the resistance goes up
enough it could cause an over-heat condition and melt the plastic or worse.
The solution is to use a Wire Ferrule and crimp it onto the wire, then you stick that into
your clamp connection and tighten.
You will notice that my connections in the two photos above are square so the four sided crimp
works well. But there are other types that are round. If you tightened on the corner you could
have a connection that will loosen over time again. This would be less likely if you have the
6-sided crimp like below.
