This harness carries low-voltage control and sensor signals between the unit's control board and its connected components through a keyed 16-pin connector. Melted, chafed, or corroded harnesses cause intermittent faults, no-heat\/no-cool calls, and error codes that are easy to misdiagnose as a bad board. Swapping in the correct factory harness restores reliable, plug-in connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eComponent: 16-pin control wiring harness\u003c\/li\u003e\n\u003cli\u003eConnector: Keyed 16-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 uses the correct connector keying, pin count, wire gauge, and color coding, so it plugs in without splicing or guesswork. Generic or repaired harnesses risk pin mismatches and crimp failures that create new intermittent faults. For control wiring, the factory harness is the safe, correct choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — disconnect power, unplug the old harness at both keyed ends, route the new harness along the same path, and reconnect. About 10–20 minutes.
