It gives the top station its own clean route into the system so the wiring isn’t fighting for space with the lower helm. Once it’s paired with the lower harness and the right helm-to-helm extensions, both stations respond the same way and stay in sync. It’s a simple harness, but it helps a large multi-engine layout feel more organized and easier to run.\u003c\/p\u003e\n\u003chr data-start=\"549\" data-end=\"552\"\u003e\n\u003cp data-start=\"554\" data-end=\"1132\"\u003e\u003cstrong data-start=\"554\" data-end=\"570\"\u003eKey Features\u003c\/strong\u003e\u003cbr data-start=\"570\" data-end=\"573\"\u003e    • \u003cstrong data-start=\"599\" data-end=\"629\"\u003eNext Gen DTS Upper Harness\u003c\/strong\u003e – Designed for quad-engine, dual-helm rigs.\u003cbr data-start=\"673\" data-end=\"676\"\u003e    • \u003cstrong data-start=\"702\" data-end=\"727\"\u003eUpper-Station Pathway\u003c\/strong\u003e – Carries throttle, shift, and system data from the upper helm.\u003cbr data-start=\"791\" data-end=\"794\"\u003e    • \u003cstrong data-start=\"820\" data-end=\"838\"\u003eOEM Connectors\u003c\/strong\u003e – Factory plugs that seat firmly and stay locked.\u003cbr data-start=\"888\" data-end=\"891\"\u003e    • \u003cstrong data-start=\"917\" data-end=\"941\"\u003eClean Routing Layout\u003c\/strong\u003e – Helps avoid cramped wiring and tight bends behind the upper dash.\u003cbr data-start=\"1009\" data-end=\"1012\"\u003e    • \u003cstrong data-start=\"1038\" data-end=\"1063\"\u003eDual-Helm Integration\u003c\/strong\u003e – Works with the matching lower harness and helm-to-helm extensions.\u003c\/p\u003e\n\u003chr data-start=\"1134\" data-end=\"1137\"\u003e\n\u003cp data-start=\"1139\" data-end=\"1320\"\u003e\u003cstrong data-start=\"1139\" data-end=\"1170\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/strong\u003e\u003cbr data-start=\"1170\" data-end=\"1173\"\u003e    • Next Gen Digital Throttle and Shift\u003cbr data-start=\"1234\" data-end=\"1237\"\u003e    • Quad engine\u003cbr data-start=\"1274\" data-end=\"1277\"\u003e    • Dual-helm layouts\u003c\/p\u003e\n\u003chr data-start=\"1322\" data-end=\"1325\"\u003e\n\u003cp data-start=\"1327\" data-end=\"1767\"\u003e\u003cstrong data-start=\"1327\" data-end=\"1363\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/strong\u003e\u003cbr data-start=\"1363\" data-end=\"1366\"\u003eWith its own dedicated path, the upper helm feels more natural and predictable during throttle bumps and shifting. You don’t get the hesitation that shows up when both stations share a cramped or improvised wiring run. It also makes future service easier because the upper-station wiring is easy to see and follow instead of buried under extra cables. The whole setup feels calmer and better balanced.\u003c\/p\u003e\n\u003chr data-start=\"1769\" data-end=\"1772\"\u003e\n\u003cp data-start=\"1774\" data-end=\"2020\"\u003e\u003cstrong data-start=\"1774\" data-end=\"1789\"\u003eWhy Buy OEM\u003c\/strong\u003e\u003cbr data-start=\"1789\" data-end=\"1792\"\u003eOEM harnesses fit the DTS system exactly the way Mercury intended.
