It links the integrated control board to the unit's switches, sensors, and blower circuit. Melted connectors, rodent damage, or corroded pins cause intermittent operation, no-heat\/no-cool faults, and error codes — this pre-terminated harness restores reliable signaling without splicing individual wires.\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\u003c\/li\u003e\n\u003cli\u003ePart Type: Low-voltage control wiring harness\u003c\/li\u003e\n\u003cli\u003eWire: Color-coded, factory-crimped terminals\u003c\/li\u003e\n\u003cli\u003eFits Model: WGPH4543AMAB\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM harness arrives with the correct 16-pin housing, pin-out, and wire colors so it plugs straight into the board — no guessing at terminations.
