It carries the low-voltage and control signals between the unit's control board and its components through a keyed 16-position connector, ensuring every circuit lands in the correct terminal. Melted, chafed, or rodent-damaged harnesses cause intermittent faults, no-heat\/no-cool calls, and error codes — a fresh harness restores reliable communication throughout the system.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eCompatible Model: APH1642M41AA (Heat Pump)\u003c\/li\u003e\n\u003cli\u003eConnector: 16-pin keyed plug\u003c\/li\u003e\n\u003cli\u003eWire: Color-coded, factory-terminated leads\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (also fits Amana equivalents)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM harness\u003c\/strong\u003e arrives pre-terminated with the exact pin-out, gauge, and connector keying the control board expects — plug it in and go.
