Original Sumitomo 7165-0797

The Component: Genuine Sumitomo 7165-0797 (Alternative code: 09871PLGQD-GR). Automotive wiring harness cavity dummy blind plug (Light Gray / Neutral).

Series Taxonomy: Sumitomo TS 025 Sealed Series / ISO 19689 OBDII Interconnect Platform. A high-density, ultra-compact Japanese automotive wiring ecosystem engineered explicitly to handle micro-signal routing while maintaining absolute weatherproof isolating security.

Terminal Interface: Designed with a precise 0.64mm (.025 size) tab cavity profile, engineered to slide perfectly into vacant terminal lanes of Sumitomo TS 025 and corresponding Yazaki 0.64mm sealed female plug or male cap connector housings.

Locking and Sealing Security: Environmentally seals open, unused connector cavities to a high-performance IP67/IPX9K rating across an operating threshold certified from -40 to +125 degrees Celsius. Formed from a high-grade Nitrile Butadiene Rubber (NBR) compound, it relies on concentric compression ribs to friction-lock inside the cavity lane, blocking out high-pressure water spray and atmospheric contamination.

Mating Complement: Seals unused terminal lanes directly across the TS 025 sealed connector family, commonly filling vacant slots in housings that interface with Toyota factory connector part number 90980-09871 or Subaru equivalent wiring frames.

Common Applications: Extensively specified across prominent global passenger vehicle and motorcycle electrical architectures, most notably within Toyota, Lexus, Subaru, Honda, and Mazda factory wiring harnesses. Most frequently deployed inside multi-way engine control units (ECU), transmission controllers, complex body control modules (BCM), and ISO OBDII diagnostics links where specific pin positions remain unpopulated from the factory. Highly prone to perishing, mechanical tearing, or accidental loss during field terminal depinning operations, leaving open moisture pathways into the connector block.

Sumitomo 7165-0797 TS 025 Series 0.64mm Light Gray Weatherproof Connector Cavity Blind Dummy Plug

Prevent catastrophic moisture tracking, eliminate terminal oxidation risks, and safeguard unpopulated circuit lanes inside your vehicle's harness block with the genuine Sumitomo 7165-0797 0.64mm sealed cavity dummy blind plug. Precision-manufactured to strict Tier-1 original equipment automotive engineering parameters by Sumitomo Wiring Systems, this light gray NBR rubber sealing pin is an absolute industry staple for executing professional harness repairs and aftermarket loom modifications. Engineered around the compact TS 025 series footprint, it creates a secure, long-term environmental block inside open terminal pathways that prevents ambient water ingress or airborne dust from compromising adjacent active signal tracks.

The 7165-0797 dummy plug is molded from a premium, heat-stabilized, oil-resistant Nitrile Butadiene Rubber (NBR) compound finished in a factory light gray tone, ensuring exceptional elastic recovery, dimensional stability, and total immunity to degradation from engine lubricants, chemical solvents, and road salt spray. Its sleek, cylindrical body profile with tiered sealing rings allows it to glide easily into unpopulated terminal positions, expanding slightly under compression to establish a water-tight barrier that protects critical sub-circuits. This authentic component allows independent auto-electrical specialists, motorsport harness builders, and fleet technicians to maintain factory-grade environmental protection across high-exposure engine bay and chassis wiring junctions.
