However, full engine harness replacement is a complex procedure that involves disconnecting the battery, removing engine bay components to access all harness routing points, and carefully transferring connectors one at a time to ensure correct placement. Professional installation by a qualified Subaru technician or experienced mechanic is strongly recommended to avoid damage to sensors, the ECU, or electrical connectors. Always disconnect the negative battery terminal before beginning any electrical work.\u003c\/p\u003e","brand":"Subaru OEM","offers":[{"title":"Default Title","offer_id":43159626383456,"sku":"sub24020AD080","price":493.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1398\/9853\/files\/Subaru-OEM-Engine-Wiring-Harness-03-05-WRX-24020AD080_f0083ea7.jpg?v=1791629259","url":"https:\/\/www.importimageracing.com\/products\/subaru-oem-engine-wiring-harness-03-05-wrx-24020ad080","provider":"Import Image Racing","version":"1.0","type":"link"}
