TE Connectivity 174257-2 Econoseal J 4-Way Female Plug
The Component: Genuine TE Connectivity 174257-2 (Alternative: 0-0174257-2 / Part Alias: ECONOSEAL-J MK-2 PLUG ASSY 4P) 4-way female automotive sealed connector housing plug. Econoseal J Series Mark II+ (.070) 4-position 2-row socket receptacle casing (Black / PBT / Sealed / Cable Mount Inline Shroud / Mating Tab Width 1.8mm).
Applications & Fitment: Designed as a high-reliability factory original equipment (OE) harsh-environment connection solution for low-voltage signal and sensor configurations. Most notably specified across prominent Japanese passenger car grids (including Nissan and Toyota platform architectures) as the definitive female plug interface for under-hood wiring runs, critical pressure senders, exhaust temperature monitoring systems, and perimeter sensor networks.
Engineered specifically to perform flawlessly within tight engine bay compartments where space limitations demand a highly compact, multi-row footprint. Highly vulnerable to primary external thumb-latch locking arm snapping if pried roughly when brittle from cold engine cycles, or face-shroud tracking alignment distortion if forced blindly against misaligned male mates during workshop troubleshooting.
