Mercury – K-Plane Y Harness | Dual Tab Sensor Splitter | 84-895820T02

Overview

Dual K-Plane setups need a clean way to bring both tab sensors into a single interface point, and this harness does exactly that. The Mercury 84-895820T02 K-Plane Y Harness links the bullet-style tab sensors from a dual-tab arrangement to the four-pin tab interface connection. It keeps the wiring tidy, the readings consistent, and the rigging easier to manage when both tabs need to report cleanly to the system.

Key Features

• Dual-Tab Y Split – Combines the left and right bullet tab sensor leads into one clean output.
• 4-Pin Interface Link – Connects directly to the four-pin tab interface for position reporting.
• K-Plane Specific – Designed for Mercury K-Plane systems with bullet-style tab sensors.
• Clean Rigging Solution – Organizes dual-sensor wiring without improvised splices or adapters.
• OEM Connector Fit – Factory ends ensure a tight, reliable SmartCraft-ready connection.
• Marine-Ready Construction – Built to handle vibration, spray, and long-term offshore use.

Compatibility

• Mercury K-Plane dual tab systems
• Bullet-style tab sensors
• Four-pin tab interface modules
• SmartCraft tab-position reporting setups

Performance & Practical Benefits

This Y harness keeps the dual K-Plane system reporting smoothly by sending both tab positions through a single, organized connection. With the sensors tied in cleanly, the tab interface receives accurate data without the noise or inconsistency that comes from hand-built Y-splits. It reduces clutter around the transom or bilge and makes the system easier to troubleshoot or service later.

Why Buy OEM

K-Plane sensors require precise wiring and stable connections for accurate trim-position reporting. Mercury’s OEM Y harness maintains the correct pin layout and shielding, preventing the intermittent faults common with aftermarket splices. The factory build holds tight in harsh marine conditions and keeps the system performing the way it should.

FAQ

Q1: When is this K-Plane Y harness needed?
Whenever a dual K-Plane setup uses bullet tab sensors and needs both signals routed into a single four-pin interface.

Q2: Does the harness change how the tabs operate?
No. It only manages the sensor wiring—the tabs themselves function normally.

Q3: Is installation difficult?
No. It plugs directly into the bullet sensors and the four-pin tab interface.

Q4: Will this harness work in saltwater?
Yes. The cable and connectors are designed for long-term marine exposure.

Q5: Does the Y harness affect trim-position accuracy?
No. It delivers clean, stable signals to the interface module for correct reading.
