Frequently Asked Questions (FAQ)

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

Q: Do I need a special tool to attach wires to this connector?
A: Yes, using a standard open-barrel terminal crimper (such as a JST, Dupont, or ATX crimping tool) is highly recommended to ensure a firm, gas-tight mechanical grip between the metal terminal and your wire before snapping it into the plastic housing.

Q: How do I ensure the pins don't back out when plugging it in?
A: When inserting the crimped terminal into the rear of the plastic housing, push firmly until you hear or feel a small "click." This indicates that the metal locking tang on the terminal has successfully engaged with the internal plastic retention slot, preventing it from sliding back out under tension.
