FGear Vehicle Physics (v1.4)

Good morning everyone,
So currently I am using FGear Plugin to control my truck and it’s work well with steering system that I am using but here is the issue I don’t know how to create a widget for it so that the user can map the control on its own, its kinda confusing to simplify it, I tried using Simple Controller plugin and the issue is that Simple controller use float values to map things but FGear use Names and float values from standard input and enhance input so can anyone suggest me a better mapping option that I can use to create my widget?
I am using wheel.
