Futaba 3tpv controller

[garage-boo]

I’m trying to make the dt-3 button control my warn zeon10 winch, but only running into a brick wall. The switch on the handle/grip WILL control it, but I’d rather use the channel 3 button that is positioned in front of the steering wheel. I go into the settings menu and it gives me the choice of assigning the dt-3 button to run channel 3 or adjust dual rate. Even when I select channel 3 all it does is adjust the dual rate. It does this even when I select turning the switch on the grip to off. Like I said the switch will run the winch, but the dt-3 button is in a handier location. I’m using a yeah racing winch controller, but I don’t think anything on it is causing the issue. Any help would be greatly appreciated.
