I had one small red wire with mine and it is wired from a hot wire when the ignition switch in the on position. It is a small red wire for the provided switch that powers the forward/reverse switch for the winch. It sends the power to the relay that the main power is used to send the large wires to the winch. I wired mine using the wire that supplies the 12v power plug on side of Foreman, which is hot when the ignition switch is in on position.
