Get at least a 100 watt soldering iron or gun and some 60/40 rosin core solder because they're both suitable for electrical work. Practice on some scraps of wire or other connectors first, you don't want to be experimenting on your hall sensor, as you've already found out. Heat up the iron/gun until you can easily melt some solder on the tip for good conductivity. Apply heat to the connector and wire assembly. Once they are good and hot, with your fourth hand, feed in some solder and let it flow into the junction between the wires. In quick, smooth succession, remove the solder and heat and hold the two pieces still together until it cools as a unit. Then insert the pin(s) back in the back of the connector. Enough heat is key here. The solder should flow in between the individual strands of the wire and should be shiny silver when it cools. Bluish or bronze-colored solder joints were too cold when they formed and the bond will be electrically resistive. This is why '92-'94 cruise control modules don't work- cold solder joints.
As an alternative, crimp on the connector, then heat the wire-to-connector assembly and flow some solder in as a second connection. In fact, this way is better because it will only require three hands- one for the gun or iron, one to feed solder, and one to hold the work. I tend to use the valve cover gasket or lifting ring as a work "station." Just don't let the whole connector sit on a huge piece of metal or it'll never warm up. If you hold the wire or connector with pliers, hold it at least an inch away from where you'll be soldering or the pliers will sink all the heat away and you'll be there for a long time.
You have to get both parts good and hot, so don't hold them in your fingers. Ask me how I know.
You may be able to get on with a crimped-on connector, but soldering it well will give you some perfectionist points, and chances are it'll hold together through vibration better.
