It uses a round plug connector on the boat side and terminates in a red plug, making it straightforward to identify and connect during installation. The harness runs 20 feet long, giving installers enough length to route wiring from the transom-mounted engine connection point forward to the helm or console-mounted control box without needing to splice in extension wiring.\u003c\/p\u003e\u003cp\u003eConstructed with a polycarbonate (PC) housing at the connector, the harness is built to withstand the vibration, moisture, and temperature swings typical of a marine engine compartment and helm run. Because this harness is dedicated to Johnson\/Evinrude outboard electrical systems, it is intended as a direct replacement or upgrade for the boat-side portion of the engine-to-control wiring, restoring a clean, secure connection between the outboard and the control box.\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 18-99447\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Johnson\/Evinrude Outboard Boat-Side Wiring Harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Round Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug Color:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 20 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polycarbonate (PC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282396312\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Johnson\/Evinrude outboard engine electrical systems, connecting the engine to the remote control box.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-99447 wiring harness connect?\u003c\/strong\u003e The Sierra 18-99447 is a boat-side wiring harness that connects a Johnson\/Evinrude outboard engine to its remote control box.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long is the 18-99447 harness?\u003c\/strong\u003e It measures 20 feet long, which is enough to route from a transom-mounted Johnson\/Evinrude outboard connection point to a console or helm-mounted control box.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of connector does this harness use?\u003c\/strong\u003e The 18-99447 uses a round plug connector on the boat side, terminating in a red plug for easy identification during installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the plug on the Sierra 18-99447 made of?\u003c\/strong\u003e The plug housing is made of polycarbonate (PC), chosen for durability in a marine engine compartment environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99447 compatible with all outboard brands?\u003c\/strong\u003e No, the 18-99447 harness is built for Johnson\/Evinrude outboard electrical systems and is not designated for other outboard brands.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-99447 harness weigh?\u003c\/strong\u003e The Sierra 18-99447 boat-side wiring harness weighs 2.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99447 come with any OEM cross-reference numbers?\u003c\/strong\u003e No OEM cross-reference or replacement part numbers are listed for the Sierra 18-99447 harness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the plug on this harness?\u003c\/strong\u003e The boat-side plug on the Sierra 18-99447 is red.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-99447 be used to replace a damaged boat-side harness?\u003c\/strong\u003e Yes, the Sierra 18-99447 is intended as the boat-side wiring harness connecting a Johnson\/Evinrude outboard to its control box, making it suitable for replacing a worn or damaged harness in that role.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99447 harness pre-terminated with connectors?\u003c\/strong\u003e Yes, the Sierra 18-99447 ships with a round plug connector already installed on the boat side for direct connection to the control box.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988444491995,"sku":"SIE-18-99447","price":297.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-473-9410_lg__86982.1722497961.500.750.jpg?v=1785188157","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-99447-boat-side-wiring-harness-20-ft-round-plug-for-johnson-evinrude-outboards-mpn-18-99447","provider":"Good Vibes Marina","version":"1.0","type":"link"}
