These are new plug sets for making new looms, replacing existing connectors and other projects.
This is the 2 pin set. There is an alternative 2 pin set available.
It comes with the male and female plastic connector and 4 pins, 2 male, 2 female.
crimp the pins/terminals to wires and insert them into the plastic connector until a feint click is heard.
They come as shown in the first photo, the plastic plug set and pins/terminals to match.
You don't have to use all 4 pins just use what you need.
I also have connectors with 3 / 4 / 6 / 9 pins
