It plugs straight into the engine’s 4-pin lead and carries trim, coolant temp, oil pressure, and tach signals cleanly to the dash. On the water, it helps the gauges stay steady and cuts down on the flicker or dropouts that show up with tired or makeshift wiring. It’s a simple, flexible option for DTS boats that need a longer reach.\u003c\/p\u003e\n\u003chr data-start=\"614\" data-end=\"617\"\u003e\n\u003cp data-start=\"619\" data-end=\"1103\"\u003e\u003cstrong data-start=\"619\" data-end=\"635\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"635\" data-end=\"638\"\u003e    • \u003cstrong data-start=\"664\" data-end=\"686\"\u003e17 ft Total Length\u003c\/strong\u003e – 2 ft gauge lead + 15 ft DTS extension.\u003cbr data-start=\"727\" data-end=\"730\"\u003e    • \u003cstrong data-start=\"756\" data-end=\"780\"\u003e4-Pin DTS Connection\u003c\/strong\u003e – Direct plug-in at the engine harness.\u003cbr data-start=\"820\" data-end=\"823\"\u003e    • \u003cstrong data-start=\"849\" data-end=\"873\"\u003eAnalog Gauge Outputs\u003c\/strong\u003e – Trim, coolant temp, oil PSI, tach.\u003cbr data-start=\"910\" data-end=\"913\"\u003e    • \u003cstrong data-start=\"939\" data-end=\"959\"\u003eFlexible Routing\u003c\/strong\u003e – Ideal for consoles set farther forward.\u003cbr data-start=\"1001\" data-end=\"1004\"\u003e    • \u003cstrong data-start=\"1030\" data-end=\"1049\"\u003eOEM Wire Colors\u003c\/strong\u003e – Matches Mercury’s factory layout for clean rigging.\u003c\/p\u003e\n\u003chr data-start=\"1105\" data-end=\"1108\"\u003e\n\u003cp data-start=\"1110\" data-end=\"1315\"\u003e\u003cstrong data-start=\"1110\" data-end=\"1141\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1141\" data-end=\"1144\"\u003e    • DTS outboards\u003cbr data-start=\"1183\" data-end=\"1186\"\u003e    • DTS V6 \/ V8 outboards\u003cbr data-start=\"1233\" data-end=\"1236\"\u003e    • DTS MCM 4.5L\u003cbr data-start=\"1274\" data-end=\"1277\"\u003e    • DTS MCM 6.2L\u003c\/p\u003e\n\u003chr data-start=\"1317\" data-end=\"1320\"\u003e\n\u003cp data-start=\"1322\" data-end=\"1695\"\u003e\u003cstrong data-start=\"1322\" data-end=\"1358\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1358\" data-end=\"1361\"\u003eThe combined harness length makes routing easier on bigger boats or layouts where the dash sits a long way from the motor. It creates a clean, uninterrupted path for analog signals, which helps the gauges behave predictably. If your old harness is short, stiff, or causing intermittent readings, this setup smooths things out quickly.\u003c\/p\u003e\n\u003chr data-start=\"1697\" data-end=\"1700\"\u003e\n\u003cp data-start=\"1702\" data-end=\"1987\"\u003e\u003cstrong data-start=\"1702\" data-end=\"1717\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1717\" data-end=\"1720\"\u003eOEM DTS wiring follows Mercury’s exact pinout and uses connectors that stay tight, even when the boat’s bouncing around. Off-brand harnesses can cause odd gauge behavior or loose-fit issues. With OEM, the readings stay steady and troubleshooting becomes a lot easier.\u003c\/p\u003e\n\u003chr data-start=\"1989\" data-end=\"1992\"\u003e\n\u003cp data-start=\"1994\" data-end=\"2164\"\u003e\u003cstrong data-start=\"1994\" data-end=\"2001\"\u003eFAQ\u003c\/strong\u003e\u003cbr data-start=\"2001\" data-end=\"2004\"\u003e\u003cstrong data-start=\"2004\" data-end=\"2051\"\u003e1.
