This 16-position harness links the control board to key low-voltage and switching components, carrying signal and power between the board and the unit's sensors, relays, and motor controls. Melted connectors, chafed insulation, or corroded pins cause intermittent faults, no-heat\/no-cool calls, and error codes — a fresh OEM harness eliminates flaky connections.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1378700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e 16-pin control wiring harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e 16-position keyed plug (factory pinout)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e APH1560M41BA (Goodman\/Amana package heat pump)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Plug-and-play OEM replacement — no splicing required\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Wiring harnesses are not universal. The B1378700 uses the exact connector housing, keying, wire gauge, and pin assignment the APH1560 control board expects. Generic pigtails require cut-and-splice work that introduces resistance and failure points. The factory harness keeps the low-voltage circuit clean and code-compliant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Difficulty:\u003c\/strong\u003e Moderate (3\/5). Kill power at the disconnect, photograph the existing routing, unplug the old harness at both ends, route the new harness along the same path, and reconnect. No wire cutting needed. Roughly 30–45 minutes. Confirm connectors click fully seated before energizing.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058293457267,"sku":"GOODMAN-15741","price":34.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-16-pin-wiring-harness-for-aph1560m41ba-b1378700","provider":"National HVAC Parts","version":"1.0","type":"link"}
