It uses a cannon plug connector to link the outboard's engine-mounted wiring to the boat's control and ignition circuits, providing a secure, weather-resistant connection point that is standard on Mercury Mariner powerheads. Engine wiring harnesses like this one carry the electrical signals and power needed for ignition, gauges, and engine monitoring, so a sound connector and properly rated wiring are essential to reliable engine operation. At 0.8 pounds, the 18-99484 harness is a manageable, straightforward component to handle during installation or replacement of an aging or damaged engine harness. As a Sierra part, it is identified by part number 18-99484 and UPC 808282396022 for accurate ordering, helping boat owners and marine technicians source the correct electrical component for Mercury Mariner outboard electrical system service and repair work.\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 18-99484\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Brand:\u003c\/strong\u003e Mercury Mariner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Cannon Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercury Outboard Electrical System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282396022\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-99484 wiring harness used for?\u003c\/strong\u003e The Sierra 18-99484 is an engine wiring harness used to connect the electrical wiring on Mercury Mariner outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard brand does the 18-99484 harness fit?\u003c\/strong\u003e The 18-99484 harness is built for Mercury Mariner outboard engines as part of Sierra's Mercury Outboard Electrical System line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-99484 harness use a cannon plug connector?\u003c\/strong\u003e Yes, the Sierra 18-99484 engine harness connects using a cannon plug connector.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-99484 harness weigh?\u003c\/strong\u003e The 18-99484 wiring harness weighs 0.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC number for the 18-99484 harness?\u003c\/strong\u003e The UPC for the Sierra 18-99484 wiring harness is 808282396022.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-99484 a genuine Sierra marine part?\u003c\/strong\u003e Yes, 18-99484 is a genuine Sierra part number for a Mercury Mariner engine wiring harness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is 18-99484 classified under?\u003c\/strong\u003e Sierra classifies part 18-99484 under its Mercury Outboard Electrical System category.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra publish OEM cross-reference numbers for the 18-99484 harness?\u003c\/strong\u003e No OEM cross-reference numbers are published for the Sierra 18-99484 wiring harness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-99484 harness heavy to handle during installation?\u003c\/strong\u003e No, at 0.8 pounds the 18-99484 wiring harness is light and easy to handle during installation or replacement.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988445212891,"sku":"SIE-18-99484","price":233.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/CDI-414-6277_lg__61278.1722498913.500.750.jpg?v=1785189053","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-99484-wiring-harness-for-mercury-mariner-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
