It links the control board to the outdoor fan and compressor circuit, delivering the exact keyed connectors and factory wire gauge your system was built around. When a harness melts, corrodes, or a pin backs out, intermittent no-cool or no-heat faults follow — this direct-fit replacement restores clean, reliable connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConnector: 5-pin keyed plug\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana heat pump, model APH1549M41AB\u003c\/li\u003e\n\u003cli\u003eType: OEM factory-spec harness\u003c\/li\u003e\n\u003cli\u003eWire: color-coded, correct AWG for the circuit\u003c\/li\u003e\n\u003cli\u003ePart number: B1378701\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM harnesses use the correct pin geometry and insulation rating so connectors seat fully and resist heat near the compressor.
