New to site, new owner 2013 Sportsman 400HO

Hello everyone!
Retired from the USMC and living in Eastern North Carolina. Just purchased a 2013 Sportsman 400 HO. I am installing a new winch and it is asking me to conect wire (red and supplied with winch cable) into a wire on Sportsman that works with the turning on and off of the key….chcked the back of the ignition and there is six (I believe) wires going into the back….which wire should I use?????
Thank-you
Allen
