Mercury – Analog Gauge Harness (Non-DTS, 14-Pin) | Helm Connection Lead | 84-892990T15
Overview
This 15-foot harness plugs into the non-DTS 14-pin helm connector and gives you a clean, direct path to run analog gauges on the dash. The extra length makes it a good fit for boats with consoles farther forward or layouts that need a longer rigging run. Out on the water, it helps the gauges read steady instead of bouncing or fading the way they do with old or stretched wiring. Simple hookup, plenty of reach, and built for Mercury’s non-DTS systems.
Key Features
• 15 ft Length – Great for mid-size and larger boats needing extra routing distance.
• 14-Pin Helm Plug – Connects straight to non-DTS helm harness.
• Analog Gauge Leads – Supports trim, tach, temp, oil PSI, and other dash gauges.
• OEM Pin Layout – Matches Mercury wiring colors and pin positions.
• Marine-Durable Build – Handles vibration, spray, and heat.
Engine & Boat Compatibility
• 2006+ non-DTS Mercury outboards with 14-pin connectors
• MCM / MIE engines using 14-pin helm harnesses
• Works with 84-896537 harness
• Analog dash-gauge installations
Performance & Practical Benefits
With more length to work with, routing is cleaner and less cramped. Gauges settle down and read more reliably because they’re getting a clean signal straight from the helm harness. It’s an easy upgrade if your old harness has gotten stiff, corroded, or inconsistent, and it keeps the dash behaving the way it should.
Why Buy OEM
OEM harnesses match Mercury’s pinout and connectors exactly, so there’s no guesswork and no hunting down electrical gremlins. They hold up better to vibration and weather than aftermarket versions, which helps keep gauge readings honest.
FAQ
1. How do I know this is the right harness?
If your boat uses a non-DTS 14-pin helm connector and you need a 15-ft analog lead, this is the correct one.
2. Does it support digital gauges?
No—this harness feeds analog dash gauges like trim, tach, temp, and oil PSI.
3. Can I shorten it if needed?
Yes—extra length can be coiled neatly, but cutting isn’t recommended.
4. Any special tools required?
No—just plug it in at the helm and route it cleanly.
5. What are signs the old harness is failing?
Random dropouts, bouncing needles, or gauges that quit intermittently.
