Yazaki 7123-6214-40 58X 1-Way Female Sealed Plug | Auto-Click

Includes terminal and seal

The Component: Genuine Yazaki 7123-6214-40 (Alternative reference: 7123621440 / Part Name: X01FGY). 1-Way female automotive sealed connector plug housing for socket receptacle contacts (Light Gray / Sealed).

Series Taxonomy: Yazaki 58 Connector X Type Sealed Series. A high-reliability, large-format Japanese automotive environmental interconnect platform engineered by Yazaki to deliver total weatherproof protection, low contact resistance, and flawless performance under intense physical vibration.

Terminal Interface: 1-pin single-cavity isolated channel layout designed explicitly to house a standard heavy-duty 6.3mm (.250 size) wide female socket receptacle contact (such as Yazaki 7116-2873 or 7116-2874).

Locking and Sealing Security: Environmentally sealed to an IP67 waterproof and dustproof classification, engineered to operate flawlessly inside a continuous temperature threshold certified from -40 to +85 degrees Celsius. Utilizes an integrated internal silicone perimeter sealing ring combined with a matching rear wire rubber insulation seal to isolate the raw electrical path completely. Equipped with an internal primary terminal locking lance channel structure to ensure positive Terminal Position Assurance (TPA) and prevent contact pin back-out under heavy axial wire harness pulling or chassis harmonics. Structural mating retention relies on a heavy-duty mechanical locking latch that clicks firmly over the mating counterpart plug rail.

Mating Complement: Connects inline wire-to-wire or wire-to-device by mating directly onto its corresponding 1-way male tab partner housing assembly or device pin shroud configuration within the Yazaki 58 X Sealed Series profile (commonly cross-referenced as 58X-1P variant).

Common Applications: Extensively specified as a factory original equipment (OE) mainstay across prominent global automotive networks, most notably within Nissan, Toyota, Lexus, Hyundai, and KIA engine infrastructure. Universally recognized across the auto-electrical repair trade as the definitive wiring harness repair pigtail for starter motor solenoids, starter automatic relays, and high-amperage engine compartment auxiliary links (frequently cross-referenced as Nissan service part 24008-9DN7D or Bosch service assembly J-48817-187). Highly vulnerable to external locking latch snapping, engine bay thermal embrittlement, or structural shell fracturing if pried open aggressively during routine starter motor overhauls or diagnostic troubleshooting.

Yazaki 7123-6214-40 58X Series 1-Way Sealed Female Starter Solenoid Plug Housing

Eliminate erratic starting failures, clear slow-cranking ignition dropouts, and reinstate maximum factory-correct environmental insulation at your ignition circuit with the genuine Yazaki 7123-6214-40 1-way female sealed automotive connector housing. Precision-manufactured to strict Tier-1 original equipment global automotive engineering parameters by Yazaki, this 1-pin 6.3mm heavy-duty contact carrier block is an indispensable piece for executing professional starter solenoid pigtail fabrications, loom restorations, and clean wire harness repairs. Designed with an ultra-stable single-cavity matrix optimized around the 58 X Type terminal footprint, it creates a solid, zero-clearance conduction channel that safely runs continuous reference currents up to 20A without risking localized resistance spikes.

The 7123-6214-40 carrier block is injection-molded from a premium, heat-stabilized Polybutylene Terephthalate (PBT) compound finished in a factory light gray profile, ensuring outstanding structural impact defense, high dimensional stability under torque, and complete immunity to chemical degradation from common engine oils, hot oil vapor, battery acids, and road salt spray. Working in absolute uniformity with its internal silicone perimeter compression seals and single-wire insulation rubber seals (such as 7157-3571-80), it forms an impenetrable shield that completely blocks ambient moisture, road grime, washdown spray, and abrasive dirt from tracking into the active terminal lane. This authentic replacement component allows independent auto-electrical specialists, fleet diagnostics garages, and custom automotive builders to deliver reliable, factory-correct wiring restorations.
