Smitty XRC8 drawing power when off

Hi folks,

I have been having some issues with dead batteries in the morning so I thought it was a good time to test for a parasitic leak. I tested all of my accesories and the wiring was OK. I then tested the winch and lo and behold I was getting almost a 2amp parasitic draw. How do I troubleshoot this at this point? The wiring is super simple so I am not sure what I should do. Is there a disconnect/switch that I can put inline to the battery? I am looking for a good/quick fix/

Thanks

 

One if these would solve the issue if you don't want to find where the power is going.
