I have some breadboard wires as below photo, how can I take away the jumper out of the wire, I've tried to push the the slit on the jumper with no luck!


You have to gently lift the black plastic flap away from the uninsulated terminal below while pushing the wire further in; this will allow you to slip the wire and terminal out from the header connector. I recommend using a hobby knife that you can slide under the flap.

  • \$\begingroup\$ you'll need to cut away the metal part of the connector anyway since it's crimped for sure. \$\endgroup\$ – Vladimir Cravero Apr 9 '14 at 8:52
