Review on ATV Winch Contactor Solenoid: Upgrade for 63070 62135 74900 2875714, Fits Ramsey, Warn, Superwinch Champion 2500 3000 3500 4500 lb by Andrew Arneson

The instructions provided are minimal. It's obviously not hard to figure out what goes to the big terminals (battery +/- and winch +/-). However, the controller cables are not labeled and not described in the instructions. so you have to figure it out through trial and error. I would recommend doing this prior to installing the solenoid on the vehicle as it is constantly being fitted and removed during testing. Overall I would buy it again because it worked great on the track. I soaked it in muddy water and it's still swans. However, I would have liked better instructions.
