Mercury - Mid Triple Helm Harness Quad Engine Next Gen DTS Helm Harness 98-8M0165541. OverviewThis harness handles the middle helm on a quad-engine, triple-station DTS setup. It gives the mid helm its own clean route into the system so the wiring isn't crammed in with everything else. When all three stations are tied together with the right harnesses, the controls feel smoother and the layout doesn't turn into a jumble. It's a small piece, but it makes a big setup easier to live with.. Key Featu
