This secondary harness handles a dedicated 5-conductor circuit — typically a sensor, switch, or motor lead group — tying it cleanly into the unit's control system. Damaged insulation, a loose connector, or a burnt pin on this circuit can trigger nuisance faults and unreliable operation. Restoring it with the correct factory harness returns the connection to spec.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e B1378701\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 5-pin OEM plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Control \/ signal wiring harness assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e APH1642H41AA (Goodman package heat pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis harness uses the exact connector keying and wire gauge specified for the APH1642H41AA.
