64320-1319 CMC Series 48-Way Brown Female Housing

Terminals not included

The Component: Genuine Molex 64320-1319 (Alternative: 0643201319) 48-way female automotive sealed hybrid connector housing plug. CMC Series 48-circuit 4-row high-density socket receptacle casing (Brown / Polyester PBT / Sealed / Left-Hand Wire Output / Mat Sealed / UPC: 883906129811).

Applications & Fitment: Designed as a primary factory original equipment (OE) wiring harness connection solution for high-density engine control units (ECUs), powertrain modules, automatic transmission controllers, and complex body electronics networks. Universally specified across global passenger cars, transport trucks, buses, and agricultural machinery as the definitive master interface block for high-pinout computing modules. Engineered as a high-performance hybrid infrastructure that groups high-speed data logic paths and heavy electrical power lines into a single compact footprint. Highly vulnerable to mechanical perimeter latch block fracturing if pried aggressively when brittle from cold engine-bay cycles, or internal silicone mat-seal tearing if wire contacts are extracted using non-specified workshop tools.
