A2: Yes, samples are available. You can place a sample order through our online store link: www.ylcnc-auto.com, or contact us directly to arrange sample delivery and evaluation.

Q3: Is special tooling required to install this connector?

A3: Standard crimping tools compatible with the terminal size are sufficient for installation. The connector uses a positive-latch design that mates by hand, and terminals can be removed with a standard extraction tool if needed.

Q4: Which vehicle models is this connector compatible with?

A4: This connector is designed for applications involving Toyota. It cross-references OE NO. 6189-0694, so it is compatible with any vehicle that originally uses the 6189-0694 connector. Always verify the OE number against your vehicle's parts catalog.

Q5: Are both male and female versions available?

A5: Yes, both male and female types are available for selection. You can choose the gender that matches your harness design, or order mating pairs for complete wire-to-wire connections.

Q6: Does the black housing color indicate anything specific?

A6: The black housing color is primarily for visual identification and to match the original equipment color coding. It does not affect the electrical performance or sealing capability of the connector.
