Mercury – DTS AGI Harness (With SC Gauges) | SmartCraft Gauge Link | 892486K07

Overview
This DTS AGI harness is built for setups already running SmartCraft gauges. It uses the 3-pin gauge link to pull clean data for tach, trim, fuel level, block temp, and oil pressure/level straight from the PCM. Out on the water, it keeps those readings steady and helps cut out the weird flicker or random dropouts that happen with old harnesses. It also has transient-voltage protection onboard to keep the PCM safe from spikes.

Key Features
    • 3-Pin SmartCraft Gauge Link – Feeds SC gauges directly.
    • Multi-Gauge Support – Tach, trim, fuel level 1, block temp, oil pressure/level.
    • Voltage Suppression Built In – Protects the PCM from electrical spikes.
    • DTS Ready – Works with digital throttle-and-shift systems.
    • OEM Wiring Layout – Matches Mercury’s pinouts for supported PCMs.

Engine & Boat Compatibility
    • PCM0309
    • PCM0702
    • PCM0802
    • PCM8002
    • PCM112

Performance & Practical Benefits
Once it’s installed, the gauges usually read smoother and react quicker because they’re getting a clean signal from the PCM. It simplifies the wiring on boats that already have SmartCraft gauges in place—no adapters, no guesswork, just a solid connection. You get steadier readings, fewer odd glitches, and a tidier rigging path overall.

Why Buy OEM
OEM DTS harnesses fit tight, have the right shielding, and follow Mercury’s wiring exactly. That means fewer surprises, fewer bad readings, and no fighting with cheap connectors. Most boaters stick with OEM for PCM-linked harnesses because these systems don’t tolerate off-brand wiring.

FAQ
1. How do I know this is the right harness?
If you’ve got SC gauges and a DTS engine running one of the listed PCMs, this is the correct harness.

2. Does it replace a J-Box?
No—this is for gauge linking, not system distribution.

3. What gauges will it support?
Tach, trim, fuel level 1, block temperature, and oil pressure/level.

4. Is the install complicated?
It’s mostly plug-and-play—connect to the PCM, route it cleanly, and plug into your SC gauges.

5. What does a bad harness look like?
Multiple gauges acting up at once—jumping, flickering, or dropping out.
