Hard to say without the wiring diagram and instructions.
Usually winches have black/red for connecting to battery terminals, and two different colors (yellow/blue?) for connecting the contactor to the winch, to avoid confusion.
Then there is usually another couple of thing red/black wires to go to keyed power to operate the switch/solenoid.
Without seeing some diagrams for your winch, it's hard to say.
Can you take a photo of the instructions and any wiring diagrams and upload it?
