Frequently Asked Questions (FAQ)

Q: Does this connector come with wires attached?
A: No, this specific variant is sold "without wire." It includes the plastic housing and female crimp terminals, allowing you to crimp on your own custom lengths and gauges of wire.

Q: Do I need a special tool to attach wires to this connector?
A: Yes, it is highly recommended to use a standard terminal crimping tool (such as a Dupont, JST, or ATX crimper) to properly secure the metal terminals onto your stripped wire before snapping them into the plastic housing.

Q: How do I ensure the pins don't back out when plugging it in?
A: When you crimp the wire and push the metal terminal into the back of the plastic housing, you should hear a small "click." This indicates that the tiny metal retention tang on the terminal has successfully locked into the plastic slot, preventing it from backing out under tension.
