What I did for my winch was hook onto the wires coming out the back of my 12v plug in, winch I used a Yamaha wire harness(5KM-86171-00-00) and plug into the plug going to the 12v outlet so I didn't have to do any splicing. It was just plug and play. Please post pictures of your install as I have been thinking about adding heated hand grips to my Kodiak for winter time use.
