adamey, the winch is on a Joyner Trooper T2 OHV, not as hefty or as good as your Warn, and stall current is my main worry, INHO, the current should burn the lead right off the NFET, but the data sheet says it can handle 75A, I plan to carry a bypass for emergency failures. I looked at infra red, but they don't have ready made modules like the RF remotes and the ones I'm looking at have a momentary setting which I will use, may eat batteries because it works only while pushing the button, something like this **broken link removed**, but I will take another look at mechanical relays.
Thanks

another comment, my original set up that failed looks very similar to this one,**broken link removed** , one concern is that the coil draws 2 amps, that's 24 watts of heat and after a while the whole relay is too hot to touch.
