The 49-pin configuration is used for complex multi-circuit harness interfaces — ECM sub-connectors, body control module connections, and cab-to-chassis sub-harness interfaces where 49 circuits must pass through a single sealed connector. IP67 waterproof construction ensures reliable operation in underbody and exterior mounting locations on commercial vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 2301238-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e TE Connectivity\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Count:\u003c\/strong\u003e 49 pins\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP67\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Glass-filled nylon (PA66-GF), UL94 V-0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -55°C to +125°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e ECM, BCM, and main harness connections in commercial vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e49-Pin Connector — Application Context\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eECM sub-connectors:\u003c\/strong\u003e Secondary ECM connectors on commercial diesel engines carrying sensor and actuator circuits not included in the main ECM connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody control modules:\u003c\/strong\u003e BCM connections for lighting, door, and body circuit control on trucks and buses\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCab-to-chassis:\u003c\/strong\u003e Sub-harness connections between cab and chassis electrical systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAgricultural ECM:\u003c\/strong\u003e Engine and implement control module connections on agricultural equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003ch4\u003eHow do I identify the correct replacement for 2301238-1?\u003c\/h4\u003e\n\u003cp\u003eCross-reference 2301238-1 in the TE Connectivity catalog (te.com) to verify specifications. Verify: pin count (49), gender (male plug or female receptacle), locking mechanism, and mounting configuration. The part number is typically molded into the connector housing. For commercial vehicles, the vehicle manufacturer’s parts catalog lists the connector part number for each harness location.\u003c\/p\u003e\n\n\u003ch4\u003eWhat contacts are compatible with 2301238-1?\u003c\/h4\u003e\n\u003cp\u003eCross-reference the connector part number in the TE Connectivity catalog to identify compatible contact part numbers.
