It delivers the correct gauge wiring, color coding, and factory-crimped connectors to link the control board, limit switches, gas valve, and blower circuit. Brittle insulation, melted connectors, or rodent-chewed wires cause intermittent faults and lockouts — a fresh factory harness restores clean, reliable connections and eliminates the guesswork of splicing individual leads.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1225020\u003c\/li\u003e\n\u003cli\u003eType: Multi-circuit control wiring harness\u003c\/li\u003e\n\u003cli\u003eConnectors: Factory pre-terminated, keyed plugs\u003c\/li\u003e\n\u003cli\u003eInsulation: High-temperature rated for furnace use\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT090-5A and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM harness plugs directly into existing components with the exact connector keys and lead lengths, so there's no cutting, crimping, or wire-matching.
