Mercury – Analog Gauge Harness | DTS Engine Link | 84-8M0095716

Overview
This 15-foot analog gauge harness plugs into the engine’s 4-pin lead and gives you clean signals for trim, coolant temp, oil pressure, and tach. The extra length makes it handy for consoles that sit farther forward or rigging paths that need more reach. On the water, it helps the gauges stay steady instead of flickering or dropping out from tired wiring. It’s a simple plug-in harness built for modern DTS engines.

Key Features
    • 15 ft Length – Long enough for center consoles and forward rigging runs.
    • 4-Pin Engine Connector – Direct plug into the engine harness.
    • Analog Outputs – Trim, coolant temp, oil PSI, and tach.
    • OEM Wiring Map – Uses Mercury’s correct pinout and wire colors.
    • Flexible Marine Jacket – Built to handle heat, spray, and vibration.

Engine & Boat Compatibility
    • DTS outboards
    • DTS V6 / V8 outboards
    • DTS MCM 4.5L
    • DTS MCM 6.2L

Performance & Practical Benefits
The longer run gives you room to route the harness cleanly without stretching or splicing. Once installed, gauges react smoothly and hold steady because they’re getting a clean signal straight from the engine. It’s a simple way to freshen up a dash or add analog gauges to a DTS setup without dealing with extensions or patchwork wiring.

Why Buy OEM
OEM harnesses fit tight, resist vibration, and follow Mercury’s wiring layout exactly. That means fewer weird gauge issues and no guesswork with connectors or pin positions. Most boaters stick with OEM because the gauges simply behave better with the right harness.

FAQ
1. How do I know this is the right harness?
If your DTS engine has a 4-pin analog lead and you need a longer run, this is the correct harness.

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

3. Is 15 ft too long for smaller boats?
It can be coiled neatly, but it’s ideal for consoles farther forward.

4. Do I need special tools?
No—plug it in, route it cleanly, and connect the gauges.

5. What are signs the old harness is failing?
Jumping needles, dead gauges, or random dropouts.
