Mercury – 4-Position Trim Switch Adapter | Zero Effort Control Link | 84-896394T01

Overview
This adapter ties a dash-mounted triple or quad trim switch into a set of Zero Effort Controls on mid-2000s Gen II DTS boats. It basically lets the older dash trim setup “speak the same language” as the control system without any cutting or homemade wiring. If your boat uses ZEC and you still want to run the multi-engine trim pad at the dash, this little adapter keeps everything working the way it should.

    • 4-Position Adapter – Connects triple/quad dash trim pads to Zero Effort Controls.
    • For Triple and Quad Rigs – Built for larger multi-engine setups.
    • Gen II DTS (2006–2007) – Designed for these specific model-year systems.

Performance & Practical Benefits
With the right adapter in place, the trim pad and the controls stay in sync. You don’t get the odd delays or uneven trim response that happen when the wiring doesn’t match the control system. It also keeps the rigging behind the dash cleaner and easier to follow later on—something that matters a lot on multi-engine boats where space gets tight fast.

Why Buy OEM
OEM adapters match Mercury’s wiring layout perfectly and hold up well to vibration, heat, and spray. The connectors stay tight, and the system reads the trim signals the way it was designed to.
