The Mercury 84-898059T15 Tab Extension Harness Assembly adds fifteen feet of clean, OEM-grade cable so the tab system can be routed neatly from the helm to the actuators or control modules. It keeps the wiring organized, avoids tight stretches, and helps the system respond smoothly without strain on the original harness.\u003c\/p\u003e\n\u003chr data-start=\"536\" data-end=\"539\"\u003e\n\u003cp data-start=\"541\" data-end=\"557\"\u003e\u003cstrong data-start=\"541\" data-end=\"557\"\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"561\" data-end=\"650\"\u003e\n\u003cstrong data-start=\"561\" data-end=\"584\"\u003e15-Foot Extension –\u003c\/strong\u003e Adds significant reach for trim tab wiring across larger boats.\u003c\/li\u003e\n\u003cli data-start=\"653\" data-end=\"743\"\u003e\n\u003cstrong data-start=\"653\" data-end=\"681\"\u003eOEM Tab Harness Design –\u003c\/strong\u003e Built specifically for extending Mercury trim tab circuits.\u003c\/li\u003e\n\u003cli data-start=\"746\" data-end=\"849\"\u003e\n\u003cstrong data-start=\"746\" data-end=\"777\"\u003eClean Routing Flexibility –\u003c\/strong\u003e Helps reach helms, transoms, or control modules positioned far apart.\u003c\/li\u003e\n\u003cli data-start=\"852\" data-end=\"936\"\u003e\n\u003cstrong data-start=\"852\" data-end=\"878\"\u003eSecure Connector Fit –\u003c\/strong\u003e Factory-style ends ensure a tight, reliable connection.\u003c\/li\u003e\n\u003cli data-start=\"939\" data-end=\"1029\"\u003e\n\u003cstrong data-start=\"939\" data-end=\"967\"\u003eStable Signal Transfer –\u003c\/strong\u003e Maintains smooth tab response across the full added length.\u003c\/li\u003e\n\u003cli data-start=\"1032\" data-end=\"1116\"\u003e\n\u003cstrong data-start=\"1032\" data-end=\"1056\"\u003eMarine-Ready Build –\u003c\/strong\u003e Handles vibration, moisture, and long-term hull movement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1118\" data-end=\"1121\"\u003e\n\u003cp data-start=\"1123\" data-end=\"1140\"\u003e\u003cstrong data-start=\"1123\" data-end=\"1140\"\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-start=\"1144\" data-end=\"1170\"\u003eMercury trim tab systems\u003c\/li\u003e\n\u003cli data-start=\"1173\" data-end=\"1219\"\u003eTab harness routes requiring extended length\u003c\/li\u003e\n\u003cli data-start=\"1222\" data-end=\"1268\"\u003eHelm-to-transom wiring paths on larger boats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"1270\" data-end=\"1273\"\u003e\n\u003cp data-start=\"1275\" data-end=\"1311\"\u003e\u003cstrong data-start=\"1275\" data-end=\"1311\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1313\" data-end=\"1661\"\u003eThis harness gives the rigging enough slack to route tab wiring in a cleaner, less stressful way.
