For those of you who wish to solder the connections. When you look at the pins you will see that there are two diffrent sets of flaps that are suppose to get crimped. The first set, closest to the pin, are for the bare wire. The second set, on the end of the connector are to be crimped over the insulation. The first set is for the electrical connection. The second set are to hold the wire so any flexing takes place away from the crimp. This is to reduce any chance of the wire breaking off. When you solder the connector, solder only were the wire is crimped for electrical connection and then only crimp the second set. If you solder the whole thing there is a greater chance that the wire will snap off at the beginning of the solder joint, due to vibration or wire movement. You will also need to be very quick with the soldering iron so as to not induce too much heat into the wire and cause srinkage of the insulation or wicking of the solder up the wire. Remember that the wire should be supple not stiff after the last crimp.
