This plug-in harness carries low-voltage control and sensor signals between the control board and the unit's components. When wiring becomes brittle, chafed, or a connector pin corrodes, you get intermittent faults, failed staging, or a no-heat\/no-cool condition. A fresh OEM harness restores clean, reliable connections without splicing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eConnector: 16-pin keyed plug assembly\u003c\/li\u003e\n\u003cli\u003eComponent: Control \/ signal wiring harness\u003c\/li\u003e\n\u003cli\u003eEquipment: Heat Pump (packaged)\u003c\/li\u003e\n\u003cli\u003eFits Model: APH1642M41AB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1378700 arrives pre-terminated with the correct pin-out, wire gauge, and keyed connector so it plugs directly into the factory board.
