I believe that is the answer. I am glad I asked the questions. Now all I have to do is locate a suitable switch and a location to install it. The other issue is the fuse. I hope to find an empty spot in the stock fuse block. That will help with the OE look I am going for.
You'll actually need two fuses, or at least one fuse and a circuit breaker. You need to fuse the lead powering the relay coil (do it before the switch), and a fuse or circuit breaker on the #2 going to the relay. You want that one as close to the battery as you can get it. I like the Bussmann brand of circuit breakers that you can find in most auto parts places.
This is what I used (I used a 150A one) in my truck to protect the wiring for the 3kw inverter I installed in the back. I mounted it under the hood, close to the battery, using self-drilling, self tapping stainless sheet metal screws (and sprayed a little undercoat on the other side of the panel where the screws came through). The cable is also strapped down to the sheet metal just before and after this, so that vibration of the cable can't loosen the terminals.
They're a little pricey, but good protection. Fully waterproof and manually resettable. Manually resettable is important, because a circuit that heavy is going to spark and arc like hell if it shorts, and if the circuit breaker is one of the "self-resetting" kind it's going to cool down, reset, short and spark again. Rinse, lather, repeat until the battery dies, something ignites and incinerates the truck, or you manage to get it disconnected. And it makes it easy to disconnect power from the winch by just tripping the test button.
