UPDATE:
Since nobody helped me anywhere, I managed to find a solution myself
For others that somehow may need the solution
In 5.5 I started a new vehicle template WITH rawinput plugin already included, then it lets you set up your wheel properly, in IMC steering wheel it may not pick up the correct pedal axis, like for me, throttle and brake pedals were switched
I assigned correct ones, and it works
From there I will clone things that I need into my project
Essentially follow Seredias’s tutorial for this one, but know that you need a new vehicle template imported to the project with rawinput already added there, make sure to toggle on the “Use steering wheel input” boolean in VehiclePlayerController
