Mercury – Ignition Adapter Non DTS 14 Pin to 10 Pin | Ignition Harness Adapter | 84-896539T05

Overview

This non DTS ignition adapter is used when pairing a fourteen pin boat harness with a ten pin engine connection. It’s commonly needed during repowers or engine upgrades where the existing control wiring stays in place. Instead of reworking the entire ignition harness, this adapter keeps the setup clean and straightforward. It’s a small part that saves time and keeps the rigging looking intentional.

Key Features

• Fourteen Pin to Ten Pin Conversion – Connects a fourteen pin boat harness to a ten pin engine ignition port.
• Non DTS Mechanical Design – Supports traditional mechanical control systems without digital throttle and shift.
• Secure Mounting Bracket Included – Helps keep the adapter supported and protected during operation.
• Marine-Grade Electrical Build – Designed to handle vibration, moisture, and engine compartment heat.

Engine & Boat Compatibility

• Mercury outboards
• Mechanical remote control systems
• Engine Control Module equipped engines
• Legacy ten pin ignition series

Performance & Practical Benefits

Ignition response stays smooth and predictable after the conversion. Starting behavior feels normal, with no hesitation or signal loss. The adapter allows wiring to route cleanly without strain on the connectors. In real use, the system behaves like a factory-matched setup.

Why Buy OEM

OEM adapters are built to Mercury’s exact electrical specifications. That ensures proper resistance and clean signal communication between the harness and engine. Connector fit remains tight in harsh marine environments. OEM parts help avoid intermittent ignition issues over time.

FAQs
