Mercury – 2-Pin Extension Harness (20 ft) | Rigging Accessory | 84-8M0191742

Overview
This 20-foot extension harness gives you plenty of length to run the electric steering actuator wiring through the rig tube and up under the cowl without forcing a tight or awkward route. It’s meant for boats where the actuator sits farther back or when the wiring path takes a longer turn than usual. Each actuator uses its own harness, which keeps the electrical connection relaxed and dependable. A clean wiring run usually helps the steering feel steadier at slow speeds.

Key Features
 • 20-Foot Length – Extra reach for long rigging paths or big boat layouts.
 • 2-Pin Connector – Plugs directly into the actuator’s wiring.
 • Smooth Routing – Helps avoid sharp bends and stretched wire runs.
 • One Per Actuator – Each actuator needs 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 network
 • Single- and multi-station boats

Performance & Practical Benefits
The extra length lets you route the harness naturally instead of forcing it through cramped spaces. That reduces strain on the wiring and helps the actuator get a cleaner signal. You’ll usually feel the difference when idling around docks—steering tends to be smoother and less twitchy when the wiring isn’t stressed.

Why Buy OEM
OEM harnesses fit the connectors the way they should and use proper marine-grade insulation. They hold up better over time and help avoid the odd electrical quirks that show up with mismatched wiring. It’s a simple way to keep the system reliable.

FAQ
Q1: How do I know if I need the 20-foot harness?
A: If the wiring won’t reach the cowl comfortably—or the route is long and winding—this length is the safer option.

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

Q3: Is this okay in saltwater?
A: Yes. Just keep the connectors clean during regular washdowns.

Q4: Anything to check before installing it?
A: Make sure the rig tube is clear and the harness won’t rub on sharp edges or tight corners.

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