installing a rocker switch for winch on 2016 rancher

hello everyone I am knew to the world of 4 wheeling. I just bought a 2016 Honda rancher 420. they installed a badlands remote control winch. I would like to add a rocker switch on handle bars. could someone help me with the wiring of it. the rocker switch I am installing should be standard 3 wire. I just want a backup just in case something goes wrong with remote. and to make it easier to use in plowing snow. thanks.
