Mercury – Triple Engine Trim Harness Kit (DTS) | Multi-Engine Trim Wiring | 84-895744A02

Overview
This kit gives a triple-engine DTS setup the wiring it needs so the trim switches and Zero Effort Controls work together the way they’re supposed to. Instead of piecing together adapters or mixing old wiring with new, this kit brings everything into one clean path. It keeps the trim system steady, makes the rigging easier to follow, and takes a lot of the guesswork out of running three engines.

Key Features
• Triple-Engine Trim Harness – Routes trim signals cleanly to all three engines.
• Zero Effort Compatible – Includes what you need to tie ZEC into the trim circuit.
• Organized Layout – Keeps the system from getting cluttered behind the dash.
• OEM Connectors – Factory plugs that lock in tight and stay put.
• Complete Kit – Everything needed for a proper triple-engine trim hookup.

Engine & Boat Compatibility
• Digital Throttle and Shift
• Triple engine
• Zero Effort Controls

Performance & Practical Benefits
With the trim harness set up correctly, each engine responds at the same pace, which makes balancing the boat a lot easier. You’re not dealing with delayed trim on one motor or uneven movement across the set. The wiring behind the dash stays cleaner too, so tracking a trim issue—if one ever shows up—is much simpler. Day-to-day, the whole system just feels more predictable.

Why Buy OEM
OEM harnesses follow Mercury’s wiring logic, fit the connectors correctly, and hold up to vibration, heat, and spray. You don’t end up chasing weird trim glitches or loose connections later.
