Hammer I don't know if this will help you but I went outside in this pissing down sydney rain to take some photos for you of how mine's connected. Sorry can't give you more explanation because it was one of my friends who connected it up for me, they had to make another fuse and run another wire into the cabin through a grommet. When it was connected straight up, the switch wouldn't do anything. It was always on with my headlights until we fixed it.
anyway pics are here hope it helps if not hope you work it out.
