Mercury – Analog Gauge Harness (Non-DTS, 14-Pin) | Helm Connection Lead | 84-892990T01

Overview
This 5-foot harness plugs into the non-DTS 14-pin helm lead and gives you everything you need to run analog gauges on the dash. It also carries the choke circuit used on smaller carbureted FourStroke models—something the standard harness doesn’t always provide. Out on the water, it keeps the gauge signals clean and makes the choke function work the way it should on engines that need it. It’s a short, simple, plug-and-go piece built for a wide range of Mercury outboards and MCM/MIE engines.

Key Features
    • 5 ft Harness – Perfect for clean, short helm connections.
    • 14-Pin Non-DTS Plug – Connects directly to the helm harness.

    • Choke Circuit Support – Works on 8/9.9/15/20 hp carb FourStrokes.
    • OEM Wire Colors – Matches Mercury’s factory layout.

Engine & Boat Compatibility
    • 2006+ Non-DTS Mercury outboards (25–250 HP)
    • 8/9.9/15/20 hp FourStroke carbureted models (serials starting with “0R”)

    • Used with harness 84-896537

Performance & Practical Benefits
This harness keeps the analog gauges steady by giving them a direct, short path from the helm harness. It also restores proper choke function on smaller carbureted motors—something many owners don’t realize requires the right harness to work. With clean wiring and proper Mercury pinouts, the gauges react the way they should, and troubleshooting becomes much easier. It’s a quick upgrade for older or tired helm wiring.

Why Buy OEM
OEM harnesses match Mercury’s wiring exactly—pin positions, colors, choke wiring, everything. They hold up better to vibration and weather and eliminate the oddball issues caused by aftermarket leads. Most boaters prefer OEM because it keeps the dash and ignition behaving predictably.

FAQ
1. How do I know this is the harness I need?
If your engine uses a non-DTS 14-pin helm connector, this is the correct analog gauge lead.

2. Does this support smaller carb FourStrokes?
Yes—this harness carries the choke wire those engines require.

3. What gauges does it feed?
Standard analog functions: trim, tach, temp, oil PSI, fuel, plus choke on supported engines.

4. Is the install tough?
No—plug into the 14-pin helm connector and route to the gauges.

5. What symptoms point to a bad or missing harness?
Dead gauges, flickering needles, or a choke that doesn’t respond.
