It’s short, clean, and meant for simple dash hookups without extra adapters or long wiring runs. On the water, it helps those gauges read steady and cuts out a lot of the flicker or dropouts you get with tired wiring. Easy hook-up, easy routing, and built for modern DTS engines.\u003c\/p\u003e\n\u003chr data-start=\"512\" data-end=\"515\"\u003e\n\u003cp data-start=\"517\" data-end=\"1004\"\u003e\u003cstrong data-start=\"517\" data-end=\"533\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"533\" data-end=\"536\"\u003e    • \u003cstrong data-start=\"562\" data-end=\"584\"\u003eShort 3 ft Harness\u003c\/strong\u003e – Ideal for tidy, close-range routing.\u003cbr data-start=\"623\" data-end=\"626\"\u003e    • \u003cstrong data-start=\"652\" data-end=\"679\"\u003e4-Pin Engine Connection\u003c\/strong\u003e – Direct plug into the engine harness.\u003cbr data-start=\"718\" data-end=\"721\"\u003e    • \u003cstrong data-start=\"747\" data-end=\"771\"\u003eAnalog Gauge Outputs\u003c\/strong\u003e – Trim, coolant temp, oil PSI, and tach.\u003cbr data-start=\"812\" data-end=\"815\"\u003e    • \u003cstrong data-start=\"841\" data-end=\"863\"\u003eOEM Wiring Pattern\u003c\/strong\u003e – Matches Mercury’s color codes and pin layout.\u003cbr data-start=\"911\" data-end=\"914\"\u003e    • \u003cstrong data-start=\"940\" data-end=\"966\"\u003eFlexible Marine Jacket\u003c\/strong\u003e – Handles vibration, heat, and spray.\u003c\/p\u003e\n\u003chr data-start=\"1006\" data-end=\"1009\"\u003e\n\u003cp data-start=\"1011\" data-end=\"1216\"\u003e\u003cstrong data-start=\"1011\" data-end=\"1042\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1042\" data-end=\"1045\"\u003e    • DTS outboards\u003cbr data-start=\"1084\" data-end=\"1087\"\u003e    • DTS V6 \/ V8 outboards\u003cbr data-start=\"1134\" data-end=\"1137\"\u003e    • DTS MCM 4.5L\u003cbr data-start=\"1175\" data-end=\"1178\"\u003e    • DTS MCM 6.2L\u003c\/p\u003e\n\u003chr data-start=\"1218\" data-end=\"1221\"\u003e\n\u003cp data-start=\"1223\" data-end=\"1576\"\u003e\u003cstrong data-start=\"1223\" data-end=\"1259\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1259\" data-end=\"1262\"\u003eThis harness keeps the analog gauges steady by giving them a clean, short signal path. Trim and tach react smoothly, and pressure\/temperature gauges stop bouncing around from wiring noise. It’s a quick way to clean up the dash if you’re replacing an old harness or adding gauges to a DTS engine for the first time.\u003c\/p\u003e\n\u003chr data-start=\"1578\" data-end=\"1581\"\u003e\n\u003cp data-start=\"1583\" data-end=\"1857\"\u003e\u003cstrong data-start=\"1583\" data-end=\"1598\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1598\" data-end=\"1601\"\u003eOEM wiring fits tight, seals well, and follows Mercury’s exact pinout—no guesswork, no odd gauge behavior, no cheap connectors backing out.
