Mercury – Analog Gauge Harness | DTS Engine Link | 84-8M0095828

Overview
This 30-foot analog gauge harness plugs straight into the engine’s 4-pin connection and gives you the four basics—trim, coolant temp, oil pressure, and tach. The long reach makes it a good match for bigger boats, long rigging runs, or consoles mounted way forward. Out on the water, it helps those gauges read smooth and steady instead of flickering or cutting out like they do with tired wiring. Simple plug-in setup, lots of length to work with.

Key Features
    • 30 ft Harness – Ideal for extended rigging paths and large layouts.
    • 4-Pin Engine Plug – Connects directly to DTS engine harness.
    • Analog Outputs – Trim, tach, coolant temp, and oil PSI.
    • OEM Wire Colors – Matches Mercury’s pinout for clean routing.
    • Marine-Ready Jacket – Built to handle heat, vibration, and spray.

Engine & Boat Compatibility
    • DTS Outboards
    • DTS V6 / V8 Outboards

Performance & Practical Benefits
The long harness makes routing easier on larger boats—no stretching, splicing, or awkward detours. Once connected, gauges usually calm down and read more consistently because they’re getting a clean signal instead of one filtered through old wiring. Great for fresh installs or replacing aging harnesses that have started causing intermittent readings.

Why Buy OEM
OEM wiring fits tight, seals well, and follows Mercury’s exact layout. It handles vibration and weather far better than off-brand harnesses, which means fewer strange gauge problems down the road. With DTS rigs, sticking with OEM is almost always the safer bet.

FAQ
1. How do I know this is the harness I need?
If your DTS engine has a 4-pin analog output and you need a long run to the dash, this is the one.

2. Does this support digital gauges?
No—this harness feeds analog trim, tach, temp, and oil PSI gauges.

3. Is 30 ft too much for smaller boats?
It can be coiled neatly, but it’s mainly intended for larger layouts.

4. Any special tools required?
No—plug in at the engine, route it cleanly, and hook up the gauges.

5. What are signs the old harness is failing?
Jumping needles, dead spots, or gauges that work only part of the time.
