Adding power steering to cars?

Hello. I am currently messing around with a mod and it has no option for power steering which I am interested in adding. Im trying to make sense of the official BeamNG documentation website but I'm not very well versed in modding in Beam. So I was hoping someone could help me out here? I put the lua file in the specified directory (/lua/vehicle/controller/powerSteering.lua) and I just copy pasted the sample lines on the website. However it does not add the option to select power steering in the game. Any and all help is appreciated.

 

I've added power steering to vanilla cars before just to see what it does, but I've never noticed any difference in steering speed/accuracy/etc. Am I missing something?

 

Its for FFB (Force Feedback) wheel players so they don't have to rotate the entire desk to steer.

 

Oh okay...thanks!
