It carries power and control signals between the integrated furnace control board and the hot surface igniter (HSI), using keyed connectors so it seats correctly the first time. A cracked, melted, or corroded harness is a common cause of intermittent no-heat and ignition lockout faults — replacing it restores a clean, reliable connection to the igniter circuit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 2568416\u003c\/li\u003e\n\u003cli\u003eType: Hot surface igniter (HSI) wiring harness\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GMP100-5 gas furnace\u003c\/li\u003e\n\u003cli\u003eConnectors: Keyed OEM plug-and-play terminals\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 2568416 harness uses the correct gauge wire, connector pinout, and high-temperature insulation rated for the furnace burner compartment. Generic universal harnesses often require cutting and splicing, and lower-temp insulation can degrade near the burner. For a code-compliant, no-splice repair, the OEM harness is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Disconnect power, unplug the old harness at both ends, route the new harness along the same path, and reconnect the keyed plugs.
