This factory-terminated harness carries the low-voltage control signals between the unit's control board, defrost board, and sensor circuits. Because it is a direct OEM assembly, every pin is keyed and color-coded to match the original connector, eliminating the guesswork and miswiring risk that comes with cutting and splicing a universal cable.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1378700\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e 16-pin, keyed OEM plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Goodman\/Amana APH1536M41BA heat pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit:\u003c\/strong\u003e Low-voltage control \u0026amp; defrost signaling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (Genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eA generic patch cable forces you to identify each conductor, crimp new terminals, and hope the pin-out matches. The OEM B1378700 arrives pre-terminated and keyed, so it seats in one orientation and passes UL-rated control voltage exactly as the factory intended. For a control harness, OEM is the safer choice — a single reversed conductor can damage the control board.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Disconnect power at the breaker, unplug the old harness, route the new B1378700 along the same path, and click both connectors home.
