It is commonly used during rigging, repower, or retrofit installations when factory sensor leads fall just short of the vessel interface panel, bulkhead pass-through, or sensor mounting location.\u003c\/p\u003e\n\n\u003cp\u003eThe 5-foot length provides a clean extension without excess slack, loops, or wiring strain. By eliminating the need for splicing, this harness helps protect sensor connections from vibration, tension, and long-term wear while maintaining stable, interference-free signal transmission.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDiesel Vessel Sensor Extension – Extends existing Mercury diesel sensor wiring\u003c\/li\u003e\n\u003cli\u003e5-Foot Length – Ideal for short extension requirements\u003c\/li\u003e\n\u003cli\u003eOEM Mercury Connectors – Ensure secure fit and proper signal integrity\u003c\/li\u003e\n\u003cli\u003eFactory-Compatible Shielding – Preserves clean, stable sensor communication\u003c\/li\u003e\n\u003cli\u003eMarine-Grade Construction – Built to withstand vibration, moisture, and engine-room conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eEngine \u0026amp; Boat Compatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMercury diesel engines\u003c\/li\u003e\n\u003cli\u003eDTS diesel control systems\u003c\/li\u003e\n\u003cli\u003eAxius diesel systems\u003c\/li\u003e\n\u003cli\u003eMercury diesel electronic monitoring networks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUsed only to extend an existing vessel sensor harness.\u003c\/li\u003e\n\u003cli\u003eNot a standalone sensor or primary harness.\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for diesel sensor circuits.\u003c\/li\u003e\n\u003cli\u003eEliminates the need for splicing or custom wiring.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003e1) What is this harness used for?\u003c\/strong\u003e\u003cbr\u003e\nIt extends existing diesel vessel sensor wiring when the factory lead is slightly too short during installation or rerouting.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e2) Is this compatible with DTS and Axius systems?\u003c\/strong\u003e\u003cbr\u003e\nYes.
