Mercury – Analog Gauge Harness | DTS Engine Link | 84-8M0095826

Overview
This 20-foot analog gauge harness plugs straight into the engine’s 4-pin lead and sends clean signals for trim, coolant temp, oil pressure, and tach. The extra length makes it a good fit for larger boats or consoles mounted farther forward. On the water, it helps the gauges stay steady and cuts out the flicker or dropouts you get with old or stretched wiring. Simple hookup, long reach, and built specifically for DTS engines.

Key Features
    • 20 ft Harness – Ideal for long rigging runs on bigger boats.
    • 4-Pin Engine Connector – Direct plug-in to the DTS engine harness.
    • Analog Outputs – Trim, coolant temp, oil PSI, and tach.
    • OEM Wire Colors – Matches Mercury’s factory layout and pin positions.
    • Flexible Marine Jacket – Handles vibration, heat, and daily use.

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

Performance & Practical Benefits
With the extra length, routing is cleaner and easier—no stretching, no splicing, no awkward angles around the console. Once installed, the gauges get a stable signal right from the engine, which helps readings stay smooth and predictable. It’s a quick, reliable way to update a dash or add analog gauges to a DTS rig.

Why Buy OEM
OEM harnesses fit tighter, seal better, and follow Mercury’s wiring exactly. That means fewer gauge glitches and far less troubleshooting. Most boaters stick with OEM because DTS engines don’t play well with off-brand wiring.

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

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

3. Is 20 ft too long for small boats?
It can be coiled neatly, but it’s mainly meant for larger layouts.

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

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