I just finished installing winch on rear of my Sportsman. Mounted relay under the seat. Everything works. I hooked up the handle bar mounted switch only, hooked Red into accesory under speedo, then there are a black and green going to relay. I did not wire in the "remote" hookup. There is a white wire on the remote side that goes to the relay. But not on the handle bar mount. It works fine. In and out no problem. Anyone know what the white wire is for? It goes to the relay. I guess I could install, it is just a plug in go, but don’t see I need for the remote and extra cable all over the place. I can get pics if needed. It is a small, 18 gauge wire.

Instructions only show both handle bar mount and remote wired.
