This harness carries the high-current supply from the control board to the hot surface igniter (HSI), and its keyed, factory-terminated connectors ensure a reliable connection every ignition cycle. Melted, brittle, or corroded harness plugs are a frequent cause of no-heat calls and intermittent ignition failures — a fresh OEM harness eliminates those weak links.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Supplies power from control board to hot surface igniter\u003c\/li\u003e\n\u003cli\u003eConnectors: Keyed, factory-crimped OEM terminals\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMP100-3 furnace\u003c\/li\u003e\n\u003cli\u003eInstallation: Plug-and-play, no splicing required\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 2568416\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eA genuine \u003cstrong\u003eGoodman OEM\u003c\/strong\u003e harness uses the correct connector bodies and heat-rated wire gauge for the igniter circuit.
