Mercury - Lever 1 Harness Assembly Shift Extension Harness 84-8M0192268. OverviewThis harness gives you seven extra feet of room on the shift side of a Race DTS setup. It's marked Lever 1, so you always know exactly where it goes when you're digging around in the rigging bay. That extra length helps a lot on boats where the control station and rig center don't quite line up. It just makes the whole shift path feel less stretched and easier to work with..
