The Mercury 84-8M0165555 J-Box Y Harness provides that split. It creates a tidy, reliable way to branch a SmartCraft connection so modules, gauges, or accessories can share the network without loose adapters or makeshift junctions. Once installed, it keeps the wiring simple and the communication steady.\u003c\/p\u003e\n\u003chr data-start=\"538\" data-end=\"541\"\u003e\n\u003cp data-start=\"543\" data-end=\"559\"\u003e\u003cstrong data-start=\"543\" data-end=\"559\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"563\" data-end=\"662\"\u003e\n\u003cstrong data-start=\"563\" data-end=\"590\"\u003eY-Style Network Split –\u003c\/strong\u003e Creates two clean SmartCraft branches from a single connection point.\u003c\/li\u003e\n\u003cli data-start=\"665\" data-end=\"762\"\u003e\n\u003cstrong data-start=\"665\" data-end=\"688\"\u003eJ-Box Integration –\u003c\/strong\u003e Designed for use with SmartCraft junction box layouts and harness runs.\u003c\/li\u003e\n\u003cli data-start=\"765\" data-end=\"861\"\u003e\n\u003cstrong data-start=\"765\" data-end=\"795\"\u003eStable CAN Communication –\u003c\/strong\u003e Maintains solid data flow between connected SmartCraft devices.\u003c\/li\u003e\n\u003cli data-start=\"864\" data-end=\"945\"\u003e\n\u003cstrong data-start=\"864\" data-end=\"887\"\u003eOEM Connector Set –\u003c\/strong\u003e Uses factory SmartCraft ends for a secure, plug-in fit.\u003c\/li\u003e\n\u003cli data-start=\"948\" data-end=\"1032\"\u003e\n\u003cstrong data-start=\"948\" data-end=\"973\"\u003eRigging Flexibility –\u003c\/strong\u003e Helps organize and expand network paths without clutter.\u003c\/li\u003e\n\u003cli data-start=\"1035\" data-end=\"1133\"\u003e\n\u003cstrong data-start=\"1035\" data-end=\"1061\"\u003eDurable Marine Build –\u003c\/strong\u003e Withstands vibration, moisture, and long-term helm or bilge exposure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1135\" data-end=\"1138\"\u003e\n\u003cp data-start=\"1140\" data-end=\"1157\"\u003e\u003cstrong data-start=\"1140\" data-end=\"1157\"\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1161\" data-end=\"1181\"\u003eSmartCraft J-Boxes\u003c\/li\u003e\n\u003cli data-start=\"1184\" data-end=\"1209\"\u003eSmartCraft CAN networks\u003c\/li\u003e\n\u003cli data-start=\"1212\" data-end=\"1257\"\u003eSmartCraft modules, gauges, and accessories\u003c\/li\u003e\n\u003cli data-start=\"1260\" data-end=\"1299\"\u003e10-pin SmartCraft harness connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1301\" data-end=\"1304\"\u003e\n\u003cp data-start=\"1306\" data-end=\"1342\"\u003e\u003cstrong data-start=\"1306\" data-end=\"1342\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1344\" data-end=\"1740\"\u003eThis harness gives you more freedom when laying out a SmartCraft network.
