It provides a keyed 5-position plug-in connection between the control board and a connected component or sensor, keeping low-voltage signals clean and secure. Burnt, brittle, or loose harness connectors are a common source of intermittent operation and nuisance fault codes. Installing the correct factory harness re-establishes a solid, color-coded connection and removes a hard-to-trace failure point.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378701\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eComponent: 5-pin control wiring harness\u003c\/li\u003e\n\u003cli\u003eConnector: Keyed 5-position plug\u003c\/li\u003e\n\u003cli\u003eFits Model: WGPH4549AMAB packaged unit\u003c\/li\u003e\n\u003cli\u003eFunction: Control board \/ component interconnect\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e harness delivers the exact connector keying, pin layout, wire gauge, and color coding for a true plug-and-play fit.
