Mercury – Next-Gen ERC Extension Harness Kit (Dual) | 10-Foot Extension | 98-8M0173879

Overview
This ten-foot harness gives a dual-engine Next-Gen ERC setup some extra breathing room when the factory lead just won’t reach comfortably. Boats with longer runs or tighter rigging spaces often need a little more slack, and this extension keeps you from forcing the wiring into sharp bends. It lets the harness take a smoother path so the controls feel more natural. It’s a simple add-on that makes dual-engine installs a lot less frustrating.

Performance & Practical Benefits
With more length to work with, the harness can run in a cleaner line instead of being forced around bulkheads or cramped corners. That usually means smoother response at the controls because nothing is kinked or under tension. It also makes service easier—you can actually trace the harness without wrestling it out of tight spots. On dual-engine boats, that extra room makes a noticeable difference.

Why Buy OEM
OEM harnesses hold up to vibration, heat, and salt spray, and the connectors fit the system exactly. You avoid the annoying little glitches that show up with off-brand wiring. It’s dependable gear built for real use on the water.
