All of what he said is mostly true. However...
Hydralic winches opperate from your power steering pump, ideally, assuming you have power steering as all KJ's do.
They need the vehicle to be running too.
They are VERY strong and not suseptable to electric concerns like water and power drain.
Unfortunately most and i do say most of us use the ARB bull bar. and the ARB bull bar does not allow for a hydralic winch to be mounted inside. it is designed for electric and specificly only a couple of WARN models.
Mile Marker hydralic winches are some of the best and toughest winches you can buy.
Just not for the KJ. NOT sure of the KJ's power steering pump can handle the addition of a winch. IF somebody could design an air bag compatible front bumper that would accept a hydralic winch for the KJ, that would be kind of cool.
God knows getting your KJ in a situation where it is TOO wet for an electric winch is scary, but would be nice to have hydralic capabilities.
Speaking of winches...
here is my KJ with the new WARN M8000 and ARB on it.
