Genuine Yazaki 7157-6720. 2-Position rear spacer secondary locking clip / TPA holder (Natural).

Series Taxonomy: Yazaki 58 Connectors X Type Series Accessory. A precision-engineered structural terminal position assurance component designed to provide fail-safe contact reinforcement inside high-power Japanese automotive connector blocks.

Terminal Interface: 2-way inline structural cap configuration engineered to lock perfectly over large-scale 6.3mm (250 series) male and female terminal layouts.

Locking and Sealing Security: Serves as a vital secondary safety lock (Terminal Position Assurance) that physically bars terminals from backing out of their main structural channels under continuous wire strain. Fully validated for use inside high-performance sealed interconnect assemblies, preserving environmental integrity and preventing terminal vibration fatigue.

Mating Complement: Designed to snap seamlessly onto the matching 2-way male housing (such as part number 7222-6423-30) and its corresponding 2-way female counterpart socket housing (such as part number 7123-6423-30).

Common Applications: Extensively specified across global automotive wiring architectures, most prominently deployed within specialized high-current Honda engine management and sensor loops. Frequently utilized as the secondary locking retainer on high-amperage VTEC solenoid plugs, vehicle speed sensor (VSS) connectors, and under-hood power distribution clusters. Highly vulnerable to cracking, fatigue, or permanent loss during routine wiring modifications, diagnostic clip extractions, or field harness servicing.

Yazaki 7157-6720 58 Connectors X Type 2-Way 6.3mm Secondary Locking Clip TPA

Ensure absolute circuit reliability, eliminate dangerous contact push-out, and maintain premium structural integrity inside your vehicle's power harness with the genuine Yazaki 7157-6720 2-way secondary locking clip. Precision-manufactured to rigid original equipment Tier-1 automotive engineering standards by Yazaki, this natural-colored rear spacer holder is an essential failsafe component for high-vibration engine bay and drivetrain applications. Serving as a dedicated Terminal Position Assurance (TPA) lock, it inserts cleanly into the rear of the connector assembly to mechanically trap the crimped contacts within their designated terminal cavities.

The 7157-6720 spacer block is injection-molded from premium, high-grade Polypropylene (PP) plastic in its clean, natural factory finish. This chemical composition provides exceptional flexural endurance, high dimensional stability, and unyielding resistance to thermal fatigue across intense engine bay cycles. By completely closing off any accidental movement within the 6.3mm (250 size) cavity raster, it ensures zero intermittent contact dropouts on heavy-current signal lines. This authentic replacement piece allows auto-electrical trade specialists, diagnostic technicians, and specialist harness builders to complete reliable, factory-correct connector rebuilds.
