This factory-terminated harness carries the low-voltage control and sensor signals between the main control board and the unit's components. Pre-crimped connectors and color-coded leads make it a true plug-and-play replacement for harnesses damaged by rodents, heat, corrosion, or a previous board swap.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eFits Model: APH1543M41CA (Heat Pump)\u003c\/li\u003e\n\u003cli\u003eConnector: 16-pin plug\u003c\/li\u003e\n\u003cli\u003eType: Low-voltage control \/ sensor wiring harness\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eWiring harnesses are not universal — pin count, connector keying, wire gauge, and lead length are all specific to the control board and layout of your unit. The OEM B1378700 plugs directly into the factory connector with no splicing. Building a substitute from generic wire and connectors invites miswiring, intermittent faults, and voided warranty coverage.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate.\u003c\/strong\u003e With power off at the disconnect, photograph the existing routing, unplug the old harness, and clip the new one into place following the original path.
