This shorter harness links a furnace subassembly to the control circuit through a keyed 5-pin plug, delivering power and sensor signals over factory-crimped leads. Damaged terminals or brittle insulation lead to intermittent faults and nuisance lockouts; a factory-terminated harness restores solid, code-compliant connections without field splices.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1378701\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 5-pin keyed plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Component\/subassembly connector harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Factory-crimped, color-coded leads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Goodman GDT115-5 furnaces using the 5-pin connector\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e harness ships with the correct 5-pin keying, wire gauge, and lead lengths for a true plug-and-play swap.
