+1 for thisThis, I kid you not:
To use it, stick it into the side of the connector where the wire inserts into. If viewing the connector from the wire side with the top of the connector facing up, you want to position the insertion at dead center (12 o'clock) between the connector and the wire. There is a latch that you'll push into with slight pressure. As soon as you do that, the wire and pin comes right out.
You can thank @300wins for demonstrating this for me.
