Mercury – 2-Pin Extension Harness (15 ft) | Rigging Accessory | 84-8M0191741

Overview
This 15-foot extension harness gives you the extra length you need to run the electric steering actuator wiring through the rig tube and up under the cowl without fighting tight bends or stretched wires. It’s meant for setups where the shorter harnesses simply won’t reach cleanly. Each actuator gets its own harness, which keeps the wiring relaxed and helps the steering system respond the way it should.

Key Features
 • 15-Foot Length – Plenty of reach for longer runs and wide rigging paths.
 • 2-Pin Connector – Plugs straight into the actuator’s wiring.
 • Cleaner Routing – Helps avoid pinch points and sharp bends.
 • One Per Actuator – Every actuator uses its own extension.
 • OEM Marine Wiring – Built to hold up to spray, vibration, and daily use.

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

Performance & Practical Benefits
With the extra length, you can route the harness the “right” way instead of forcing it along a tight or awkward path. That keeps the wiring from being stressed and helps the actuator get a clean, steady signal. You’ll notice smoother steering at idle and fewer weird quirks around the dock.

Why Buy OEM
OEM harnesses fit correctly, use proper marine-grade insulation, and last longer in the real boating environment. You’re far less likely to deal with loose plugs, corrosion, or random electrical glitches down the road.

FAQ
Q1: When do I know I need the 15-foot version?
A: If the wiring feels stretched, or the route to the cowl is longer than usual, this length makes life easier.

Q2: Do I need more than one?
A: Yes—each actuator gets its own extension harness.

Q3: Is it okay for saltwater boats?
A: Yes. Just keep the connectors clean when you wash the boat down.

Q4: Anything to look for before installing?
A: Check that the rig tube is open and the harness won’t rub against sharp edges.

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