This factory-terminated harness routes low-voltage and control signals between the integrated furnace control board and the furnace's components through a keyed 12-pin connector. When wiring is chafed, melted, or a connector is damaged, replacing the complete OEM harness is faster and more reliable than splicing individual leads.\u003c\/p\u003e\u003cp\u003eThe harness arrives pre-crimped with the correct gauge wire, pin count, and keyed plug so it seats into the control board exactly like the original.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 0259F00018\u003c\/li\u003e\n\u003cli\u003eType: Wiring harness \/ connector assembly\u003c\/li\u003e\n\u003cli\u003eConnector: 12-pin keyed plug\u003c\/li\u003e\n\u003cli\u003eFits: AMH80904BXAA and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003eConstruction: Factory-crimped, correct-gauge conductors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThere is effectively no universal substitute for a molded 12-pin harness.
