Building a harness from generic wire and crimp connectors risks wrong gauge sizing, loose terminals, and miswired safeties — problems that cause intermittent faults or heat damage. OEM removes the guesswork and keeps every circuit correctly polarized and rated.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eRating: Easy to Moderate.\u003c\/strong\u003e Because the harness is pre-terminated with keyed connectors, replacement is largely a matter of unplugging the old harness and routing the new one along the same path. Always disconnect power first, and photograph connector locations before removal. The keyed plugs prevent most cross-connection errors, making this a manageable job for a confident DIYer or any technician.\u003c\/p\u003e\u003cp\u003eGenuine Goodman fit and finish at an economical price, ready to ship today.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058161303923,"sku":"GOODMAN-12432","price":9.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-wiring-harness-for-gmt115-5a-b1225020","provider":"National HVAC Parts","version":"1.0","type":"link"}
