Yazaki 7157-6560-40 6-Way 58 Series W-Type Rear Holder Clip

The Component: Genuine Yazaki high-performance sealed back clip secondary lock mechanism. 58 Series W-Type Interconnect taxonomy / 6-position single-row rear holder casing / Secondary Wire Lock Element (Classic Gray Finish / Premium Heat-Stabilized Nylon 66 / Sealed Harness System Component / 1x6 Grid Layout Rear Spacer / Wire Strain-Relief Holder Shield / Component Variant Alias: 7157-6560-40 / Global Order Reference: 7157656040 / Yazaki Component Class: Rear Holder Back Clip for 58 Connector W-Type Housing Assemblies).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) rear connector back clip and terminal strain-relief holder designed explicitly to anchor individual wire pathways and protect sealed terminal positioning inside severe structural areas, under-body chassis loops, and engine compartment layouts. This 6-way rear cap locking spacer is an essential wiring loom repair, factory maintenance update, and harness reconstruction staple across prominent Japanese automotive networks—most prominently integrated within Toyota, Lexus, Honda, and Nissan factory electrical architectures utilizing the Yazaki 58 W-Type system. It is engineered to mount directly onto the rear wire entry face of compatible 6-position multi-pole connector blocks (such as the Yazaki 7223-1864-40 female plug shell or 7122-1864-40 TPA assemblies), providing absolute physical terminal tracking and anti-vibration strain security.

It features integrated dual-stage side latch tabs that grip firmly onto the outer main connector shell, serving as a secondary mechanical lock that ensures heavy-gauge automotive wires cannot exert directional skewing force on internal single-wire seals or delicate terminal leaves under high-vibration stresses. Engineered to conform to rigid global tier-1 factory validation guidelines, its tough nylon structural framework absorbs multi-axis harness pulling forces, effectively eliminating wire-fatigue failures at the terminal crimp joints. Highly vulnerable to tab shearing or fracturing during routine diagnostic servicing if field technicians attempt forced hinge opening with un-profiled metal workshop picks instead of disengaging the secondary locking clips smoothly, making it a critical stock replacement piece for trade distributors and independent auto-electrical workshops.
