My cub has a simple headlight switch, off-dim-bright. I got an oem rear light harness to install and the diagram I have showed the hot lead to the light hooks to a screw on the switch just under the screw holding the resistor. I hooked the pink (ground) leads up with one going to the dash mount bolt and the other to the ground on the light. This ground was a redundant ground since my rear light grounds itself on the light housing. Any suggestions? The hole that housed the fuse has been replaced with a pull switch, so I could use that if the above mentioned has any problems. The only benefit of course would be that I could run the rear light independent of the headlights.
