This 16-position connector carries low-voltage control and sensor signals between the main control board and the unit's components, delivering a factory-terminated, color-coded plug that eliminates the guesswork of loose-wire repairs. Chafed, melted, or corroded harnesses cause intermittent faults, no-heat\/no-cool calls, and board damage — a fresh OEM harness restores reliable connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1378700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 16-pin low-voltage control wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 16-position keyed plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Package Heat Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e APH1548M41AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1378700\u003c\/strong\u003e arrives with the correct pin count, keying, wire gauge, and terminal crimps for a true plug-and-play swap.
