4-1437290-0 Superseal 34-way Housing

TE Connectivity 4-1437290-0 Superseal 1.0 34-Way Female ECU Plug

The Component: Genuine TE Connectivity (AMP) 4-1437290-0 34-way female automotive sealed plug connector assembly. Superseal 1.0mm Series 34-position 4-row socket receptacle casing grid (Black / PBT GF / Sealed / ECU Plug / Coding 1 / Double Lock / Wire-to-Board / Alias: 3900113-3421).

Applications & Fitment: Designed as the definitive factory original equipment (OE) high-density wiring harness repair interface solution for advanced powertrain management. Most notably specified across prominent automotive brands, commercial transport grids, marine systems, and professional motorsports platforms as a primary engine control unit (ECU) interface block, transmission control module (TCM) plug, and high-density data logging gateway. Highly vulnerable to internal terminal lane distortion or outer locking face alignment fractures if pried apart aggressively during field workshop diagnostics or aftermarket performance re-mapping.
