Mercury – 3-Pin Extension Harness (10 ft) | Rigging Accessory | 84-8M0191744

Overview
This 10-foot extension harness gives you the extra reach needed to connect the steering 3-pin lead from the rig center breakout to the electric steering actuator. It’s meant for setups where the shorter harness won’t quite make the run or where a cleaner, gentler routing path is needed. Each actuator uses its own harness, which keeps the wiring relaxed and helps the steering system respond the way it should.

Key Features
 • 10-Foot Extension – Extra length for longer or less direct wiring paths.
 • 3-Pin Connector – Plugs directly into the steering breakout lead.
 • For Electric Steering – Built specifically for Mercury electric steering rigs.
 • One Per Actuator – Every actuator needs its own extension.
 • OEM Marine Wiring – Durable, flexible insulation suited for vibration and spray.

Engine & Boat Compatibility
 • Electric steering actuators
 • Digital Throttle and Shift
 • SmartCraft rigging
 • Single- and multi-station boats

Performance & Practical Benefits
The extra length makes routing easier and helps avoid tight bends or spots where the wiring might get pinched. A cleaner wiring path usually leads to steadier steering response, especially at idle or around the dock. It also cuts down on long-term wear since the harness isn’t pulled tight or rubbing against anything sharp.

Why Buy OEM
OEM harnesses fit the connectors properly and use marine-rated wiring that holds up over time. You get reliable connections, fewer electrical surprises, and a harness that integrates cleanly with the rest of the steering system.

FAQ
Q1: How do I know if I need the 10-foot version?
A: If the 3-pin steering lead doesn’t comfortably reach the actuator, this extension fills the gap.

Q2: Do I need one per actuator?
A: Yes—each actuator uses its own extension harness.

Q3: Is it fine for saltwater boats?
A: Yes. Just rinse and keep the connector areas clean.

Q4: Anything to check before installing?
A: Make sure the route is free of sharp edges and tight pinch points.

Q5: What if steering still feels inconsistent afterward?
A: That usually points to calibration or another wiring issue, not the extension harness.
