Mercury – Triple Mid Helm Harness Triple Engine | Next Gen DTS Helm Harness | 98-8M0165540

Overview
This harness handles the middle helm on a triple-engine, triple-station Next Gen DTS setup. It gives the mid helm its own clean path into the system, so it’s not sharing tight routing with the upper or lower stations. When the full set of harnesses is installed, all three helms stay in sync without the wiring turning into a headache. It’s a straightforward part that helps a big multi-helm setup feel more organized.

Performance & Practical Benefits
With this harness in place, the mid helm responds more consistently because it isn’t relying on cramped or improvised wiring paths. All three helms feel more in sync, especially when shifting or making small throttle moves. Service work later on is easier too, since the signal path through the middle station is clean and easy to follow. It keeps a large setup from feeling tangled or uneven.

Why Buy OEM
OEM harnesses fit the DTS system the way Mercury intended, which helps avoid strange lag or mixed signals between helms. The materials hold up to vibration, heat, and saltwater far better than generic wiring. It’s the kind of component you can trust once it’s in place.
