This factory-terminated assembly links the control board to the unit's low-voltage components — pressure switches, defrost sensor, reversing valve, and contactor — through a keyed 16-position connector, delivering a clean plug-and-play replacement for harnesses damaged by heat, rodents, corrosion, or a rough previous repair.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Low-voltage control wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 16-pin keyed plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Interconnects control board to switches, sensors, and valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Factory-crimped, color-coded leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman APH1648H41AB heat pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e B1378700 arrives pre-terminated with the correct pinout, wire gauges, and lead lengths, so it seats into the board and components without guesswork.
