This harness carries line voltage from the control board to the igniter and ties in related low-voltage connections, using factory-terminated connectors and correct wire gauge for safe, reliable ignition. Damaged, brittle, or heat-melted harness insulation and corroded terminals are a frequent cause of intermittent no-heat calls and failed igniter operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 2568416\u003c\/li\u003e\n\u003cli\u003eType: HSI (hot surface igniter) wiring harness\u003c\/li\u003e\n\u003cli\u003eConnectors: Factory-matched plug terminals\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GMP050-3 gas furnace\u003c\/li\u003e\n\u003cli\u003eEquipment Type: Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine harness is pre-terminated with the exact connectors your control board and igniter expect — plug-and-go with no splicing. Generic or hand-built harnesses risk mismatched connectors, incorrect gauge, and loose crimps that create resistance, heat, and future failures. OEM keeps the ignition circuit safe and code-correct.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — 20–45 minutes. Cut power at the breaker, photograph the existing routing, unplug the old harness at each connector, and clip the replacement in along the same path away from hot surfaces. No wire cutting required. Confirm ignition sequence after power-up.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058134729075,"sku":"GOODMAN-11837","price":28.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-hsi-wiring-harness-for-gmp050-3-2568416","provider":"National HVAC Parts","version":"1.0","type":"link"}
