Mercury – 2-Pin Extension Harness (25 ft) | Rigging Accessory | 84-8M0193673

Overview
This 25-foot extension harness gives you the extra reach needed to run the electric steering actuator wiring cleanly through the rig tube and up under the cowl. It’s meant for setups where the actuator sits farther back or the shorter harnesses just don’t make it without forcing awkward bends. Each actuator uses its own harness, so the wiring stays relaxed instead of pulled tight. A proper-length run usually makes the steering feel a little smoother at idle and around docks.

Key Features
 • 25-Foot Length – Long enough for wide or winding rigging paths.
 • 2-Pin Connector – Matches the actuator plug without adapters.
 • Clean Routing – Helps avoid crushed spots and sharp, damaging bends.
 • One Per Actuator – Every actuator needs its own extension.
 • OEM Marine Wiring – Built to hold up against vibration, spray, and everyday use.

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

Performance & Practical Benefits
That extra length makes the install a lot easier, especially on bigger boats. Instead of forcing the wiring into tight corners, you can run it naturally through the rig tube, which helps the actuator get a steady signal. When the wiring isn’t stressed, steering tends to feel calmer and more predictable—something you’ll appreciate when easing into a slip or lining up on a trailer.

Why Buy OEM
OEM harnesses fit the connectors the way they’re supposed to and use proper marine-grade materials. They hold up well season after season and help you avoid the odd electrical issues that come from cheaper wiring.

FAQ
Q1: When would I choose the 25-foot version?
A: When the wiring run is long enough that the shorter harnesses won’t reach comfortably.

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

Q3: Is this harness okay for saltwater boats?
A: Yes. Just keep the connectors clean during your regular rinse-down.

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

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