I utilized a heavy duty staple and pushed it into the slot above the pin you are removing. Then if you look at the top of the molex plug, you will see what appears to be a piece that can be removed. I was able to use a small flat head to lift up on that plastic a little. After that I pushed the staple all the way, and the pin pulled out cleanly. The only thing I had to do after that, was to bend the metal back on the pin just a little so that the pin can lock when inserted again.
