YLCNC 174257-2 4 PIN Oxygen Sensor Harness Connector Auto Wiring Harness Housing

The 4-way YLCNC-0454 connector carries a Black PBT shell and waterproof seals, targeting the exact OE NO. 174257-2 position on the vehicle. YLCNC-0454 joins wires end-to-end, so the lead cross-section, length and color are freely adjustable for the original equipment circuit. YLCNC-0454 repeat quantities are predictable for distributors, while first-time customers can begin with a small evaluation order.
