FGear Vehicle Physics (v1.4)

Okay, that makes sense. Would you be able to provide some information on what I could use to call the targeted spline in the FGear Auto Drive component in a blueprint? I see the option is instance editable, but I can’t seem to figure out what to call from it to assign the spline.
If it’s C++ related could I get some detailed instructions on adjusting it, as I am decent in Blueprints, but terrible in C++ coding.
