This is a set of ten 2-prong cable harnesses with female header ends, and ten 12-inch cables so that you can populate them. Thus you can make five complete 2-pin cables with a connector on each end.
The picture on the right shows 20 wires by mistake. Obviously only 10 wires are needed to create five 2-pin cables. The package includes five red wires and five black wires.
These are perfect for jumping power and ground lines.
