I could be way off, but I'm pretty sure that the location of the steering wheel's info panels are a part of the steering wheel model.
EDIT: Alright, now, after a quick look, I'm 99% sure that I'm correct.
To find the steering wheel model and it's associated textures, look in the Cars.wad under cars/cockpits and the .gp4 file you want is 'cockpit_wheel.gp4'
