ECU Pin Electrical Help

[StoneBoy]

Hey, I was attaching a reprogrammed Jim Wolf Tech '96 ECU onto my '98 Nissan 240SX and when switching out the pins on the harness connector, I accidentally pulled one of the wires out and the pin is still stuck in the white plastic harness connector. Does anyone know what those small metal pin connectors are called? and where can I buy them? Heres a picture of what they look like, except the one i'm looking for is a smaller version.
