Trailer air supply valve

[babo18]

Hello, I am trying to find out how to map the trailer air supply valve, ( the red valve on the dash next to the yellow parking brake valve). I have seen people using it in various videos but i do not see an option for it. I see the trailer brake function, but that is the hand valve on the steering column. Any help would be appreciated.
Thank You,

you can ask the devlopers about that idea

The developers are not gonna answer simple questions like this. Stop saying stuff like that.

To the OP:

As far as I know there is not a specific mapping option for it. However if you wanted to map something like it...you can put it on the secondary option?

The game handles both valves on the same key. The animation for the trailer valve only operates when you have a trailer attached. You can not set the trailer brake manually.

Well, you can. There's a Trailer Brake option in the menu, so if you set that to a switch instead of a key, you can technically have a trailer parking brake, but only in function.

that is true
