I bought some mom-off-mom switches off of ebay (they look like the ones that sidekicksrock has) . I have one wired and installed on the backside of the solenoid box on the winch (so I don't have to hook the remote lead up when strapping down on the trailer, or for when the winch bitch needs to loosen the cable to unwind it), I have another wired in on the dash. For the one on the dash, I have it wired through a "hidden" switch under the dash, so I can kill the power to it, for when the kids are playing around in the samurai.
I have them wired through relays as well.
