This pre-terminated harness links the integrated furnace control board to the furnace's components through a keyed 12-pin plug. Melted, chafed, or corroded harness pins can cause intermittent operation, error codes, or a completely dead furnace — replacing the harness restores clean, reliable signal and power connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConnector: Keyed 12-pin plug\u003c\/li\u003e\n\u003cli\u003eType: Pre-terminated OEM wiring harness \/ loom\u003c\/li\u003e\n\u003cli\u003eFunction: Control board to component interconnect\u003c\/li\u003e\n\u003cli\u003eWiring: Color-coded to factory schematic\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDS81155CNA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e harness uses the exact pin-out, wire gauge, and connector keying as the original, so it seats correctly and matches the furnace wiring diagram with no guesswork. Generic or hand-built harnesses risk mis-pinned connections that can damage the control board or create dangerous faults. For a plug-and-play, error-free repair, use the factory harness.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty: Moderate\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eModerate (3\/5)\u003c\/strong\u003e. Cut power at the disconnect, photograph the existing connections, then unplug the 12-pin connector and any inline terminals, routing the new harness along the same path. Match wire colors to the furnace schematic before restoring power. Budget 30–45 minutes and take care to avoid pinching wires against sharp sheet-metal edges.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058077155699,"sku":"GOODMAN-10349","price":29.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-12-pin-wiring-harness-for-gds81155cna-0259f00007p","provider":"National HVAC Parts","version":"1.0","type":"link"}
