Mercury – SC100 Data Harness | 6-Inch SmartCraft Link Extension | 84-880756T05

Overview

Short runs between SC100 Series gauges sometimes need just a little extra reach. The Mercury 84-880756T05 SC100 Data Harness adds six inches of clean, OEM-quality SmartCraft extension so linked gauges can be spaced naturally on the dash. It keeps the data line tidy, avoids strain on the main harness, and makes multi-gauge layouts much easier to align.

Performance & Practical Benefits

This short extension makes it easier to lay out SC100 gauges cleanly without forcing the harness into awkward angles. The extra six inches allow more natural spacing, cleaner routing behind the dash, and less tension on the connectors. Once installed, the gauges continue to share data normally, and the helm looks more organized.

Why Buy OEM

SmartCraft communication depends on the right pin configuration and clean, properly shielded connections. Mercury’s OEM harness keeps the data stable and avoids the intermittent faults that cheap extensions can introduce. The factory ends fit securely and hold up to vibration, heat, and everyday marine use.
