FAQ

Q1: Is this connector a cross-reference replacement for OE NO. 12052600?

A1: Yes. YLCNC-0463 is a cross-reference replacement for OE NO. 12052600, with the same 5-pin layout, PBT housing and single wire seal, fitting all original automotive applications of the 12052600 connector.

Q2: Do you accept small batch trial orders? What is the MOQ?

A2: Small batch trial orders are accepted, and the specific MOQ can be negotiated flexibly. We fully cooperate with customers' testing and market expansion needs.

Q3: Can this connector be used in heavy-duty trucks and commercial vehicles?

A3: Yes. The sealed PBT housing and single wire seal design make it suitable for heavy-duty truck, construction equipment and commercial vehicle applications where durability and waterproof protection are essential.

Q4: How does the single wire seal work?

A4: A single wire seal is installed on each wire before crimping the terminal. When the terminal is inserted into the connector cavity, the silicone seal compresses against the housing wall, creating a watertight barrier that prevents moisture from entering the connection.

Q5: Is special tooling required to install this connector?

A5: 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.

Q6: Why does this connector have 5 positions?

A6: The 5-position design matches the original OE 12052600 connector circuit count, ensuring each wire has its own sealed cavity. This maintains the same electrical layout and pinout as the factory part.
