We just put lightbars on a 750 and 760. There is already wiring under the mirror arms on both sides......take the top cover off with torx screws and there will be empty plugs on both sides. The 760 has a JD globe so I mounted 2 smaller lightbars on either side of it just screwed into the roof. The 750 has AgLeader and there is a bar that overhangs the front of the roof so we just drilled 2 holes through the bar and hung a 50in curved from it. Very easy installs. Also while you are under those covers there is also an additional wire for a second beacon so I made mounts and bought beacon power posts and mounted a second beacon on both machines.
