Mercury – Lower Helm Harness Single Engine | Next Gen DTS Helm Harness | 84-8M0159747

Overview
This harness is the lower-helm side of a dual-helm, single-engine Next Gen DTS setup. It gives the lower station a clean communication path without crowding the rigging bay or forcing tight bends. You’ll still need the upper harness and the helm-to-helm extensions, but this piece handles the lower end of the system. It keeps the wiring predictable and makes the setup feel a lot more organized.

Key Features
    • Next Gen DTS Lower Harness – Built for single-engine dual-helm layouts.
    • Lower Station Routing – Handles the communication path from the lower helm.
    • OEM Connectors – Factory-fit ends that click in solidly.
    • Clean DTS Pathway – Carries throttle, shift, and system data.
    • Dual-Helm Ready – Works with the required upper harness and helm-to-helm extensions.

Engine & Boat Compatibility
    • Next Gen Digital Throttle and Shift
    • Single engine
    • Dual-helm layouts

Performance & Practical Benefits
With a proper lower-helm harness, the controls feel steadier because each station gets a clean, direct path into the DTS system. The wiring is easier to route, easier to trace later, and doesn’t end up jammed into corners. Shifts and throttle inputs tend to feel smoother when the harness isn’t stretched or cramped. It just helps both helms work together without any drama.

Why Buy OEM
OEM harnessing is built for real marine use—vibration, heat, and salt spray. The connectors stay tight and the wiring lasts longer than generic options. You avoid the odd glitches that show up when a dual-helm setup isn’t wired with matching components.

FAQ
Q1: How do I know this is the right harness?
A: If you’re wiring a single-engine boat with a lower and upper DTS helm, this is the lower-station harness.

Q2: What else do I need for a full dual-helm setup?
A: You’ll need the matching upper harness plus the helm-to-helm extension harnesses.

Q3: Does anything need calibration?
A: No—once everything is plugged in, the DTS system handles its own checks.

Q4: How does it handle saltwater?
A: Just rinse occasionally and check the connectors; it holds up fine.

Q5: What are early signs something’s wrong?
A: Laggy controls, intermittent data, or visible wear along the harness jacket.
