Slide off the cowling, snap this Mercury Cable Assembly (84-879148T50) into its receptacle, and your Zeus 3000 helm instantly speaks the trim cylinders’ language again. At just 5¼ inches end-to-end, this factory jumper tucks neatly inside the bracket—no coiling, no chafe—yet its job is huge: carrying every micro-signal that keeps your drive angles crisp and your fuel burn low.

Dialed-in details boaters appreciate

• OEM-molded 12-pin Delphi connector seals out spray and corrosion with a single click.

• Tinned-copper conductors housed in a flexible, 0.63-inch abrasion-proof jacket for signal integrity run after run.

• Slim 0.02-lb footprint won’t load the harness tray or crowd service points.

• Color-coded leads match Mercury’s wiring diagram, so troubleshooting stays simple.

Whether you’re chasing an intermittent trim fault or doing preventive winter service, replacing a tired link with this genuine assembly restores the rock-solid data flow your joystick or SmartCraft gauge depends on. No splices, no guesswork—just plug, torque, and head back to the launch knowing every trim tap will land exactly where you want it.
