EPC E-3979 (Ford WPT-986) 2-Way Female 1.5mm Sealed Connector Housing

The Component: Genuine EPC (PKC Group) high-performance sealed female receptacle connector plug housing. 1.5mm Sealed Series taxonomy / 2-position single-row female casing / Mechanical Key A Profile (Dark Gray Housing Shell / Premium Heat-Stabilized PPE/PA Composite / Sealed Waterproof / 1x2 Grid Layout / Female Coil-on-Plug and Injector Loom Plug / Component Variant Alias: E-3979 / Global Order Reference: E3979 / Automotive Loom Cross-Reference: Ford 1F1T-14A464-AB / Ford Pigtail Service Kit: WPT-986 / WPT986).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-device waterproof connection plug designed explicitly for ultra-harsh under-hood operational environments, intense cylinder-head heat soaking, and continuous engine block vibrations. This 2-pin female socket block is an absolute wiring loom repair and harness reconstruction staple across multiple major domestic and international vehicle platforms—most prominently integrated within Ford Motor Company powertrain architectures. It is standardly deployed across critical vehicle ignition configurations, serving as the primary factory connector interface for 2-pin Coil-On-Plug (COP) pencil ignition coils, select EV6/EV14 fuel injectors, and auxiliary under-hood solenoid control valves. It features an integrated mechanical top-mounted thumb locking latch that clicks firmly over the mating device header's retention ramp, paired with a high-visibility red integrated terminal position assurance (TPA) front locking insert to guarantee total terminal seating and completely eliminate contact back-out. Engineered to conform to rigid tier-1 automotive manufacturing validation guidelines, its internal cavities pair with Yazaki YESC 1.5 series clean-body female sockets and high-elasticity silicone single-wire rubber seals to form an absolute barrier against high-pressure washdowns, road spray salt misting, fine track dust penetration, and aggressive hot engine oil vapors. Highly vulnerable to top-latch snapping or housing fracturing on older vehicle platforms due to continuous extreme thermal cycling, making it a critical service item for auto-electrical workshops and field service technicians.
