This harness carries the low-voltage signal and power connections between the coil and the EST module, and is the correct replacement when the factory wiring on this circuit has corroded, chafed, or failed from heat and vibration in the engine compartment. The wiring uses copper conductors insulated with polyvinyl chloride (PVC) jacketing for durability in a marine engine environment, and terminates in Rj-series connectors for a direct plug-in fit at the coil and module.\u003c\/p\u003e\u003cp\u003eAs a Sierra part, the 18-5515 is engineered to meet or exceed the original equipment part it replaces and is backed by Sierra's Industry Leading Customer Satisfaction Warranty. It is intended as a straightforward, direct-fit replacement for engines equipped with a Delco EST distributor, restoring a reliable coil-to-module connection without splicing into or modifying the factory harness.\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 18-5515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Distributor Coil to Module Harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Engines equipped with a Delco EST Distributor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper, Polyvinyl Chloride (PVC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Rj-series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 1.77 x 7.01 x 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282361075\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eEngines equipped with a Delco EST Distributor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-5515 connect?\u003c\/strong\u003e The Sierra 18-5515 is a wiring harness that connects the ignition coil to the distributor module on engines equipped with a Delco EST distributor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this harness fit any marine engine?\u003c\/strong\u003e The 18-5515 is designed for engines equipped with a Delco EST distributor; it is not a universal fit for engines using other distributor types.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-5515 harness made of?\u003c\/strong\u003e It uses copper conductors with polyvinyl chloride (PVC) insulation, chosen for durability in a marine engine compartment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat connector type does the 18-5515 use?\u003c\/strong\u003e The harness terminates in Rj-series connectors for a direct plug-in connection at the coil and module.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-5515 weigh?\u003c\/strong\u003e The Sierra 18-5515 EST Distributor Coil to Module Harness weighs 1 pound.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-5515 harness?\u003c\/strong\u003e The 18-5515 measures 1.77 x 7.01 x 5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5515 an OEM or aftermarket part?\u003c\/strong\u003e The 18-5515 is a Sierra-branded aftermarket harness engineered to meet or exceed the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the coil to module harness?\u003c\/strong\u003e Replace the 18-5515 when the factory coil-to-module wiring on a Delco EST distributor shows corrosion, chafing, or failure that causes an intermittent or lost ignition signal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-5515 come with a warranty?\u003c\/strong\u003e Yes, the 18-5515 is covered under Sierra's Industry Leading Customer Satisfaction Warranty against defects in workmanship and materials for the useful life of the product.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-5515 harness straightforward?\u003c\/strong\u003e The 18-5515 is a direct plug-in replacement between the coil and the Delco EST distributor module, so it does not require splicing into the factory wiring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the Sierra 18-5515?\u003c\/strong\u003e The product is the coil to module wiring harness itself, part number 18-5515, ready to connect at the coil and distributor module.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988218261723,"sku":"SIE-18-5515","price":31.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5515__49993.1686574175.500.750.jpg?v=1785188058","url":"https:\/\/www.goodvibesmarina.com\/products\/delco-est-distributor-coil-to-module-harness-fits-engines-with-a-delco-est-distributor-sierra-18-5515","provider":"Good Vibes Marina","version":"1.0","type":"link"}
