Mercury – Start/Stop Extension Harness | 5-Foot Harness | 84-896380T05

Overview
This 5-foot Start/Stop extension harness gives you a little extra reach when the factory lead won’t comfortably land where you need it. It’s handy on boats where the Start/Stop pad sits farther from the rig center or the wiring path has a tight turn. Instead of stretching the cable or forcing an awkward bend, this harness lets the run fall into a cleaner, more natural route. It works on any DTS engine setup and keeps things simple behind the helm.

Key Features
    • 5-Foot Extension – Adds a bit of slack when the factory harness comes up short.

    • Works With 3-Pin Extensions – Can be paired with 10, 15, or 20-foot sections if more length is needed.
    • OEM Connectors – Factory plugs that lock in tight and stay put.

    • Start/Stop pad harness pathways

Performance & Practical Benefits
That extra five feet gives you enough room to route the harness without stressing it. The Start/Stop pad feels more responsive when the wiring isn’t kinked or stretched. Service work is easier, too—you’re not wrestling with a line that barely reaches. It’s a small add-on that helps the whole control setup feel cleaner and more relaxed.

Why Buy OEM
OEM wiring handles vibration, heat, and spray far better than generic extensions. The connectors match Mercury’s system exactly, so you don’t run into loose plugs or weird intermittent behavior. It’s dependable rigging that lasts.
