Connecting Molex Pins and Tubes
A molex connector has three parts:
The longest part is the pin or tube; this is the bottom.
The middle part is an open U with short tabs
The top part is an open U with longer tabs.
Strip the lead so that when the bare wire is in the middle part the insulation is in the top part.
Bend the short tabs onto the bare wire with needle-nosed pliers
For additional strength and conductivity solder the connection
Bend the long tabs into the insulation with needle-nosed pliers.
I've done it at least 100 times.
