It delivers line voltage from the control board to the igniter through high-temperature insulated leads and factory connectors, so ignition timing and current stay within spec. Melted insulation, brittle wires, or corroded terminals near the burner box are common failure points that cause no-ignition or intermittent lockout faults — this pre-terminated harness restores a reliable connection.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 2568416\u003c\/li\u003e\n\u003cli\u003eType: Hot surface igniter (HSI) wiring harness\u003c\/li\u003e\n\u003cli\u003eInsulation: High-temperature rated leads\u003c\/li\u003e\n\u003cli\u003eConnectors: OEM plug terminals, pre-crimped\u003c\/li\u003e\n\u003cli\u003eFits: GMP125-5 and compatible Goodman furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis OEM harness uses the correct gauge, high-temp insulation, and factory connector housings so it seats exactly like the original.
