Mercury – Key Switch with Harness Non-DTS 14-Pin | Ignition Wiring Assembly | 896537K02

The Mercury Key Switch with Harness (Non-DTS 14-Pin) is designed for mechanical outboard applications that use a non-DTS fourteen-pin ignition connection. It is commonly selected during repowers or rewiring projects where a clean, updated ignition layout is desired. The integrated key switch and extended harness help keep wiring organized at the helm without forcing tight bends or rerouting existing connections.

Maintaining a properly configured ignition wiring system supports consistent engine starting and helps reduce electrical issues caused by strained, loose, or aging connections. Secure routing, correct mounting, and routine inspection help preserve signal stability and support dependable operation over time in typical marine conditions.
