I have a 3,000 pound warn winch on the front, and a 2500 on the back, and i ran both on the same selenoid and put me a switch on it, flip it up for the front one and flip it down for the rear one. It will work!!

 

How are you interupting with the flip switch? I mean, which circuit is broken on the rear system, when the front is in use? I am trying to understand how one solenoid will operate 2 winches, but with only one at a time! The reason I ask, is because I used a flip switch to interupt the "signal" power that goes to which ever solenoid is selected, but my method requires 2 solenoids. Thanks!
