It is designed to carry the ignition and charging circuit connections between the outboard's powerhead components, providing a direct-fit replacement for boaters whose factory harness has become brittle, corroded, or damaged from prolonged marine exposure. A wire harness of this type consolidates multiple individual wire runs into a single organized assembly, which simplifies routing, reduces the chance of chafing against engine components, and helps prevent intermittent electrical faults that can cause hard starting, stalling, or charging system failures.\u003c\/p\u003e\u003cp\u003eSierra manufactures its marine electrical parts to withstand the vibration, heat, and moisture exposure typical of an outboard powerhead environment. Replacing a worn or failing harness with the correct Sierra part helps restore reliable ignition and charging performance without having to splice or repair individual wires. This harness is intended for Johnson Evinrude outboard applications within the OMC electrical system family.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-99462\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Wire Harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson Evinrude outboard electrical system\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282396411\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson Evinrude outboard motors (OMC electrical system)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99462 used for?\u003c\/strong\u003e The Sierra 18-99462 is a wire harness for the electrical system of Johnson Evinrude outboard motors, carrying ignition and charging circuit connections between powerhead components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-99462 fit any outboard brand?\u003c\/strong\u003e This harness, Sierra part number 18-99462, is designed for Johnson Evinrude outboard motors within the OMC electrical system, not for other outboard brands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99462 wire harness weigh?\u003c\/strong\u003e The Sierra 18-99462 wire harness weighs 0.9 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99462 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-99462 is a Sierra manufacturer part number, and it is sold as a Sierra-branded wire harness rather than a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace my outboard's wire harness?\u003c\/strong\u003e A wire harness like the Sierra 18-99462 is typically replaced when the factory wiring becomes brittle, corroded, or damaged from marine exposure, which can cause hard starting, stalling, or charging system faults on Johnson Evinrude outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99462 include connectors for installation?\u003c\/strong\u003e The Sierra 18-99462 is supplied as a complete wire harness assembly intended to connect into the Johnson Evinrude outboard's existing electrical system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the Sierra 18-99462?\u003c\/strong\u003e The Sierra 18-99462 wire harness carries UPC 808282396411.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan a failing wire harness cause charging problems on an outboard?\u003c\/strong\u003e Yes, a deteriorated harness can create intermittent connections in the ignition or charging circuit, and installing a replacement such as the Sierra 18-99462 addresses this on Johnson Evinrude outboard electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-99462 a DIY job?\u003c\/strong\u003e Replacing a wire harness such as the Sierra 18-99462 involves disconnecting the old harness from the outboard's electrical components and connecting the new one in the same configuration, a task within reach of an owner comfortable with basic marine electrical work.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is 18-99462?\u003c\/strong\u003e Sierra part 18-99462 is classified as a wire harness within the Johnson Evinrude outboard electrical system category.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988444950747,"sku":"SIE-18-99462","price":250.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-413-9902_lg__46664.1702910523.500.750.jpg?v=1785188689","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-evinrude-omc-outboard-wire-harness-sierra-18-99462-marine-electrical-replacement","provider":"Good Vibes Marina","version":"1.0","type":"link"}
