Mercury – Key Switch Harness Kit Non-DTS 14-Pin | Ignition Wiring Kit | 896537K15

The Mercury Key Switch Harness Kit (Non-DTS 14-Pin) is designed for mechanical outboard installations that require additional reach at the helm without transitioning to digital throttle and shift systems. It is commonly used on larger or deeper console layouts, center consoles, and refit projects where standard harness lengths are not sufficient. The extended harness length allows for cleaner routing and helps reduce strain on connectors behind the dash.

Using a properly sized ignition harness supports consistent engine starting and helps reduce electrical issues caused by stretched, stressed, or tightly routed wiring. Clean routing, secure mounting, and routine inspection help maintain stable signal flow and support long-term reliability in typical marine operating conditions.
