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.

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.

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.

I had a cable that connected two PCIE 6 pin connectors to one PCIE 8 pin. Unfortunately, it turned out I needed to adapt two PCIE 6 pin connectors to an 8 pin CPU connector, which no one makes. This tiny little tool saved the day, and allowed me to rearrange the pins on the 8 pin connector to what I needed. Like the directions say, be careful that the prongs go on the OUTSIDE of the pin, which is harder than you might think. Once you get that right, push it in, and a gentle (gentle!) tug removes the pin.

If the wire is not still connected to the connector it will release but won’t come all the way out.
