Over years of heating cycles the harness endures repeated thermal stress near the burner compartment, and cracked insulation, burnt connectors, or brittle wire strands are a common cause of intermittent no-ignition faults. This genuine OEM harness restores a clean, reliable electrical path with the correct factory terminals and pin spacing.\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\u003eCompatibility: Goodman GMPH075-4 gas furnace\u003c\/li\u003e\n\u003cli\u003eConnectors: OEM factory plug and terminals\u003c\/li\u003e\n\u003cli\u003eApplication: Ignition circuit \/ control board to igniter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 2568416\u003c\/strong\u003e uses high-temperature insulation rated for the burner enclosure and molded connectors that seat positively into the control board — no splicing or crimping required. Generic universal harnesses often ship as bare pigtails that force field splices, introduce added resistance, and can loosen under vibration. For a safety-critical ignition circuit, the exact-fit OEM part is the recommended choice.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — most homeowners and techs can swap this harness in 15–20 minutes with basic hand tools.
