This 16-circuit harness carries control and power signals between the integrated control board, the blower motor, and the air handler's low-voltage terminals. When pins corrode, insulation melts near the motor, or a connector cracks, you can get intermittent blower operation, error codes, or a no-heat\/no-cool fault that mimics a failed board. Replacing the harness restores clean, reliable connections.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConnector: 16-pin (16-circuit) plug\u003c\/li\u003e\n\u003cli\u003eFunction: Control board to motor\/terminal interconnect\u003c\/li\u003e\n\u003cli\u003eWire: Color-coded, factory-terminated leads\u003c\/li\u003e\n\u003cli\u003eFits: Goodman AEPF426016BA and compatible AEPF air handlers\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1378700\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM harness\u003c\/strong\u003e arrives pre-terminated with the correct pin-out, gauge, and connector keying — it plugs straight in with no splicing or guesswork. Generic harnesses or hand-built splices risk pin mismatches and loose crimps that can damage the control board. For anything carrying control signals, OEM eliminates the risk.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy.\u003c\/strong\u003e Largely plug-and-play: disconnect power, unplug the old harness at both ends, route the new one along the same path, and reseat the connectors until they click. Plan 20–30 minutes. Photograph the routing before removal so the replacement follows the same path away from hot or moving parts.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Direct Replacement","offer_id":63032385864051,"sku":"B1378700-GEN","price":23.95,"currency_code":"USD","in_stock":true},{"title":"OEM","offer_id":63048143765875,"sku":"B1378700","price":31.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-control-board-furnace-B1378700_2ccc78c7-8d3e-4ecf-a11e-8fe20569959e.jpg?v=1782945259","url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-16-pin-wiring-harness-for-aepf426016ba-b1378700","provider":"National HVAC Parts","version":"1.0","type":"link"}
