Militaria 11-03-0044 Connector Accessories, Mini-Fit Jr Extraction Tool, for The Removal of Mini-fit jr.Tm Crimped terminals Series from Their housings.

This is the tool. If you are trying to remove pins on mini molex this will help you more than any of those other tool sets with 100 useless tools in them.

Does not fit/work for ATX PSU connectors as described. Don't waste your money here.

I bought a kit to add a light to a miter saw. It came with a cable harness to adapt the two. While installing it, the cable pulled out of the connector, and I got this tool to recrimp the pin. The tool works great if there is a wire connected to a pin. If one pushes the wire into the connector, and then insert the tool, the pin comes out quite easily. The pin with no wire did not come out. I suppose that if I had a small enough tweezer, that I could have made it work. I was able to use the one pin where the wire was still attached, and bought a new connector and pins separately, and could reuse the pin with the wire, and recrimp the other wire to another pin. I didn't adequately crimp the wire the first time, and couldn't get that pin out of the second connector either. tldr: Difficult to remove a pin which has no connected wire.

Wear a glove if you don't want the end to hurt your hand (you must push VERY hard). It is difficult to jam the tool into the Molex housing and seems a little short (sometimes didn't reach). The metal bends easily, but I wouldn't pay more for a better metal. Although more difficult to use, a smashed paper clip can be used when this tool failed to release the pin.

I needed to repin my 4pin mini power cord and first bought the big bag of 1000 pin tools for 10$. Those are more useful for automotive. Nothing would work for the PC pins though. I got this and wow, first try pops them right out and did not damage the pins so they could be reused. This it a must have for any PC pinning you need to do.
