Mercury – Analog Gauge Harness (Non-DTS, 14-Pin) | Helm Connection Lead | 84-892990T10
Overview
This 10-foot harness plugs into the non-DTS 14-pin helm connector and gives you a clean way to run analog gauges on the dash. The extra length makes it easier to route through bigger consoles or longer rigging runs. Out on the water, it helps your gauges read smooth and steady instead of flickering or cutting out from old wiring. Simple, tidy, and built specifically for Mercury’s non-DTS setups.
Key Features
• 10 ft Harness – Good reach for consoles that sit farther forward.
• 14-Pin Helm Plug – Connects directly to non-DTS helm harness.
• Analog Gauge Leads – Supports trim, tach, temp, oil PSI, and more.
• OEM Wire Colors – Matches Mercury’s factory pin layout.
• Durable Marine Jacket – Handles vibration, movement, and spray.
Engine & Boat Compatibility
• Non-DTS Mercury outboards (14-pin harness)
• MCM / MIE engines with 14-pin connectors
• Used with 84-896537 harness
• Dash-mounted analog gauge setups
Performance & Practical Benefits
With the longer harness, routing becomes easier and cleaner—no stretching or awkward bends. Gauges usually calm down and read more consistently once they’re getting a clean signal straight from the helm harness. It’s a simple upgrade that solves a lot of random gauge behavior on older or tired wiring.
Why Buy OEM
OEM harnesses follow Mercury’s pinout exactly, so the gauges get the right signals every time. They hold up better to heat, vibration, and weather than aftermarket options. Most boaters stick with OEM because it saves a ton of troubleshooting later.
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 longer analog lead, this is it.
2. Does this include choke wiring?
No—this version is for analog gauge signals only.
3. What gauges can I run?
Trim, tach, temp, oil PSI, and other standard analog dash gauges.
4. Is installation difficult?
No—plug it in at the helm, route it cleanly, and connect the gauges.
5. What are signs the old harness is failing?
Jumping needles, dead spot readings, or gauges that only work sometimes.
